THE UNIVERSITY OF KANSAS SCIENCE BULLETIN Vol. XLI] December 23, 1960 [No. 8 Lung-Flukes of Snakes, Genera Thamnophis and Coluber, in Kansas BY Peggy Lou Stewart Abstract: Thamnophis sirtalis parietclis Say and Coluber constrictor flavi-ventris Say were trapped and examined for lung-flukes on the University of Kansas Natural History Reservation, in Douglas County, in the months of June through November, 1958. These snakes were released at the points of capture after the flukes were removed. Also, examinations were made of preserved specimens of T". sirtalis parietalis Say, T. radix haydeni Kennicott, T. sauritus proximus Say, and C. constrictor jiaviventris in the Museum of Natural History, the University of Kansas. Crow (1913) reported Natrix rhombifera, Ancistrodon ( Agkistrodon) con-tortrix, A. mokassen (= A. c. mokeson), A. piscivorus, and Sistrurus miliarus as hosts of lung-flukes in Kansas. REVIEW OF THE TAXONOMY OF SOME TREMATODES IN REPTILES Members of the order Digenea von Beneden are characterized by having the mouth opening within the oral sucker and an endo-parasitic Hfe in vertebrates. The members of the suborder Proso-stomata Odhner, characterized primarily by having a subterminal mouth, are the only representatives of the Digenea that are para-sitic in reptiles. Yamaguti ( 1958 ) reviewed 29 families in Prosostomata, of which one, the Plagiorchiidae (Luhe, 1900) Ward (1917), comprises flukes having the distinctive character of tandem, diagonal, or symmetrical testes in the posterior half of the body. Pratt (1902) defined the subfamily Reniferinae, in the family Plagiorchiidae. Pratt assigned to the Reniferinae those genera hav-ing the genital pore lateral to a point midway between the suckers: Styphlodora Looss (1899), Astiotrema Looss (1900), Renifer Pratt (1902), Ochetosoma Braun (1901), and Oistosomum Odhner (1902). Baer (1924) raised the Reniferinae to family level, Reni-feridae. (877)
