  • A new digenetic trematode, Musculovesicula magna n. sp. from a marine fish, Gymnothorax kidako caught on Pacific, Japan (Hemiuridae, Lecithochiriinae).
    A. Ichihara ----- pp. 1-3
    
    Musculovesicula magna n. sp. (Digenetic trematode: Hemiuridae, Lecithochiriinae) is described from the stomach of Gymnothorax kidako from the coast of Miyake Isl., Pacific, Japan, May 23, 1972. It differs from the most closely related species M. congeri Yamaguti, 1970 in sucker ratio, body size and entire pars prostatica is enclosed in the hermaphroditic pouch.
    
    
  • Two new digenetic trematodes, Paramonorcheides brotulidorum n. sp. (Monorchiidae) and Dinosoma lophioimi n. sp. (Hemiuridae), from deep sea fishes from Japan.
    G. Toman ----- pp. 4-7
    
    A new monorchiid trematode, Paramonorcheides brotulidorum n. sp. was collected from the intestine of Neobythites fasciatus. It differs from the closest related species P. sirembonis Yamaguti, 1938, in larger body size, larger sucker ratio, shorter esphagus, more anterior location of acetabulum, more posterior location of genital pore, and smaller eggs, surraounded by a thick coating. A new hemiurid, Dinosoma lophioimi n. sp. was obtained from the stomach of Lophiomus setigerus. The largeseminal vesicle and a tubular sheath enclosing hermaphroditic duct distinguishes it from all other species of the genus.
    
    
  • Status of the genus Glossimetra Mehra, 1937 (Family-Plagiorchidae (Lühe, 1901) Ward, 1917) in Styphlotrematinae Baer, 1924, Astiomatinae Baer, 1924 and Styphlodorinae Dollfus, 1937 complex.
    A. N. Gupta & P. N. Sharma ----- pp. 8-11
    
    Yamaguti and Skrjabin differ vitally regarding the assignment of Glossimetra Mehra, 1937 along with other common and uncommon genara under the subfamilies Astiomatinae Baer, 1924; Styphlotrematinae Baer, 1924 and Styphlodorinae Dollfus, 1937. Recognition of Astiomatinae by Yamaguti and not by Skrjabin, recognition of Styphlotrematinae by Skrjabin and not by Yamaguti on one hand and recognition of Styphlodorinae by both lends complication in the taxonomy. Exclusion of Neomicroderma Park, 1940 and Parallopharynx Caballero, 1946 from Astiomatinae along with a suggestion that Astiomatinae, Styphlodorinae and Plagiorchinae of the family Plagiorchidae Lühe, 1901 do not differ much in their diagnostic characters.
    
    
  • Studies on "Crowding effect" on Gastrothylax crumenifer and Fischoederius elongatus, the common amphistome parasites of ruminants, observed under natural conditions.
    R. S. Tandon ----- pp. 12-14
    
    It has been found in the case of Gastrothylax crumenifer and Fischoederius elongatus, the two common amphistome parasites (Trematodes) from the rumen of buffalo, that crowding has a definite effect on their size, and the development of reproductive organs. When he intensity of infection, either by its own species or other parasites also, is low they attain a very large size and remain immature. On the other hand in a heavily crowded state verysmall worms become fully mature and gravid. The reproductive organs and the eggs, however, are normal in the dwarfs.
    
    
  • Taxonomic position of Allopharynx Stroma, 1928, Microderma Mehra, 1931 and Glossimetra Mehra, 1937.
    A. N. Gupta & P. N. Sharma ----- pp. 17-18
    
    Taxonomic allocation of the genus Glossimetra Mehra, 1937 along with Allopharynx Stroma, 1928 and Microderma Mehra, 1931 are discussed. Based on phylogenetic sequential arguments it is proposed that the genera Allopharynx and Microderma be down graded to subgeneric rank under the genus Glossimetra.
    
    
  • Zoogonid trematodes from marine fishes near the Tsushima Island in the Sea of Japan.
    Sh. Kamegai ----- pp. 19-23
    
    Zoogonid trematodes collected in 1968 and 1969 are reported from marine fishes obtained near the Tsushima Islands in the Sea of Japan. Zoogonoides yamagutii n. sp. from the intestine of Plotosus anguillaris differs from the closely related species Z. acanthogobii Yamaguti, 1938 in having a larger sucker ratio and smaller eggs. Proctophantastes infundibulum n. sp. from the small intestine of Priacanthus boops is characterized by the funnel-shaped oral sucker and the esophagus being divided into two portions (esophagus proper and pseudoesophagus). Besides these two new species, Zoogonus sp. from Chrysophrys major and Deretrema nahaense Yamaguti, 1942 from Sebastodes inermis and Scorpaenopsis cirrhosa are reported.
    
    
  • Siphonaptera from small mammals in northern Honshu, Japan.
    Z. Ono & N. Takada ----- pp. 28-31
    
    Having examined 610 specimens of fleas collected at 39 localities in northern Honshu the writers have found 9 species and 3 subspecies, of which three, Hystrichopsylla ozeana, Rhadinopsylla ohnoi and Monopsylla indages lis, are new to northern Honshu.
    
    
  • A Check list of the helminths from Japan and adjacent areas. Part II. Parasites of amphibia, reptiles, birds and mammals reported by S. Yamaguti.
    Sh. Kamegai & A. Ichihara ----- pp. 33-64
    
    Preface: The present list is the second part of the series of check list of helminths from Japan and adjacent areas. It includes helminths of amphibia, reptiles, birds and mammals reported by S. Yamaguti (1933-1961). In the first part of the check list published in 1972, fish parasites alone reported bby the same author have been dealt with. In these two parts, all the helminths reported by Yamaguti from Japan and adjacent areas have been thoroughly listed up from his entire original papers. It is believed that the availability of such a list will aid future workers in identyfying parasites collected from hosts included in the list, particularly from the geographic areas covered by Yamaguti's surveys.
    Supplemental check list series on helminths of fishes from Japan including all the up to date literratures besides Yamaguti will be published in the future.
    We are indebted to Dr. Y. Imaizumi, Nat. Sci. Mus. Ueno, Tokyo and to Dr. Y. Hasuo, Yamashina Inst. Ornith., Tokyo, for information on host animals.
