right varies from 475 to 520 //. long by 55 /x thick, and the left 



from 740 to 870 fi long, with the same thickness as the right.

My observations on this species are practically identical with 

 those of Henry and Blanc; the only differences are in the size 

 of the egg, which appears slightly smaller in my material, and in 

 the size of the spicules, mine being slightly larger. 



Ph. tumefaciens, Fh. morclens. Ph. mi^nidica, and Ph. magni- 

 papilla are the only 4-uterine forms described from mammals. 

 Ph. 'inordens and Ph. numidica have teeth as in Ph. paradoxa, 

 whereas Ph. magnipa'pilla and Ph. tumefaciens have each only 

 two teeth to each lip. Ph. tumefaciens is distinguished from the 

 other three species by the mode of origin of its uteri, by the 

 absence of a common trunk portion in the female genitalia, and 

 by the reduplication of the cuticle over the caudal extremity in 

 most individuals of both sexes. 



(21) PHYSALOPXERAMAGNIPAPILLAMolin, 1860. (Text-fig. 31.) 



Some of the excellently preserved type material in the collec- 

 tion of the Vienna Museum was examined. 



The body appears smooth, but under high magnification the 

 cuticle is seen to be provided with very delicate transverse 

 sfcriations. It is slightly reflected over the base of the lips, and 

 in some females it was I'etlected over the whole of the tail in a 

 manner similar to that seen in Ph. prceputialis. 



The cervical papillae are small and spike-like, and pierce the 

 cuticle about 150 jti behind the level of the hind end of the mus- 

 cular oesophagus ; from 75 to 100 /a further back on the ventral 

 surface the opening of the excretory duct is found. 



The lips are somewhat quadrangular, with large subdorsal and 

 subventral external papillae, and each is provided with two teeth 

 of the same height; the outer tooth has a widened tip, whereas 

 the median inner tooth- is tripartite. 



The oesophagus immediately follows the lips. It is straight, 

 and forms in the female l/5'5 and in the male l/6'6 of the 

 total body-length. Its anterior muscular part is nearly 1/lOth of 

 the whole organ, is slightly thinner, and is encircled in its 

 posterior third by the nerve ring. 



Female. 



The females vary from 30 to 38 mm. long by '9 to I'l mm. 

 broad ; they are attenuated in their anterior fourth and posterior 

 fifth, and the body is terminated by a, bluntly conical tail 

 l/52nd of the body-length and having its caudal pores in its 

 posterior half. 



The vulva opens level with the surface, and its position divides 

 the body in the ratio of 1 : 2'3 ; it leads into a straight muscular 

 vagina nearly 2 mm. long by 80 /u. thick. The egg-chamber is
