1102 . MR. R. J. ORTLEPP ON THE 



Vulva divides body into ratio of 6:15. Eggs 39 x 26 /x. 



Host : Otis kouhara. Intestine. Koenigsberg. 



Seurat (1914 cZ) has identified this species as a Habroneraa. 



(88) Physaloptera bulbosa v. Linstow, 1906. 



Host : Pavo sjncifer. Stomach . 



I have recently found specimens of this parasite in the proven- 

 triculus of Pavo cristatus from India. From my observations on 

 this material I find that this parasite is not a Physaloptera, but 

 belongs to the genus Cyrnea Seurat, 1914. A detailed description 

 of it will appear in a later publication. 



(89) Physaloptera contorta Leidy, 1856. 



" Body capillary, most narrowed anteriorly with the posterior 

 4/5tli spirally contorted ; white, with the intestine brown. Lips 

 prominent, constricted from the body, trilobate. Tail short 

 conical, acute, in the male with narrow alse each furnished with, 

 five funnel-shaped pores. Length of female from 6 lines to an 

 inch ; breadth to one quarter of a line ; male from one-half to 

 three-quarters of the size." 



Hosts : Emys serrata, Emys reticulata, Cistudo Carolina, and 

 Kinosternura pennsylvanicum. Stomach. [U.S.A.] 



Baylis and Lane (1920) suggest that this species is probably 

 identical with or closely related to Spiroxys contorta (Knd., 1819), 

 Schn., 1866. I have been able to examine some specimens of 

 Spiroxys contorta obtained from Emys orbicularis, and from my 

 observations Baylis and Lane's view appears justifiable. Accord- 

 ing to Leidy's description, these parasites must be excluded from 

 the genus Physaloj>tera because of their trilobed lips. Molin 

 (1860) has already doubted the Physalopteran afiinities of this 

 species. 



(90) Physaloptera constricta Leidy, 1856. 



Length, female 1| inches, male half as long. 



Lips large, lateral, constricted from body, and trilobate. Tail 

 of male with long and narrow turgid alee ; that of the female 

 incurved, conical, and acute. 



Host: Trop)idonotus sipedon. Stomach. [U.S.A.] 



The nature of the lips definitely excludes this parasite from 

 the genus Physaloptera, no members of it having trilobed lips. 

 Baylis and Lane (1920) suggest that this parasite may be 

 a Tanqua. I agree with them in so far that it falls into the 

 family Gnathostomidag as redefined by them, but as to its closer 

 relationship to any of the genera of this family, it does not appear 

 justifiable to draw any conclusions ; Leidy's brief description of 

 the parasite is equally applicable to the genus Spiroxys as to the 

 genus Tanqua. 



Molin (1860) also expressed doubt as to this species belonging 

 to the genus Physaloptera.
