simple, cxtciulint; to near jxisterior ctul of body. Genital aperture 

 sinistral, cephalad of intestinal bifurcation, and about midway be- 

 tween margin of body and esophagus. Cirrus ])oucb about 400 //

Podocofylr laiicroluUi ditfers from all species of the genus except 

 P.- levinsciii Isaitschikov. P. odhncri Isaitschikov, P. syyiiafhi NicoU, 

 and P. pennelU Leiper and Atkinson in that the cirrus pouch does not 

 extend .posterior to the acetabulum. Of the species mentioned above. 

 P. laiiccolata resembles P. odhncri perhaps more closely than it does 

 any of the other species, but it may be distinguished from that form 

 in having distinctly lobed testes, a relatively larger ovary, and more 

 profusely developed vitellaria. P. lanccolafa has a smaller ovary and 

 a more laterally placed genital aperture, which serve to distinguish 

 it from P. levinscni. It may be differentiated from P. sygnathi by 

 the position and character of the testes and the extent of the vitellaria 

 anteriorlv. the testes being smooth and well separated, and the vitel- 

 laria not extending to the acetabulum in P. syynathi, while the testes 

 are lobed and close together, and the vitellaria extend anterior to 

 the acetabulum in P. lanceolata. This species may be distinguished 

 from P. pcnncUi in the position of the genital aperture and in the 

 length of the intestinal ceca, the genital aperture being situated at the 

 level of the pharynx and the intestinal ceca extending only as far 

 as the level of the posterior margin of the posterior testis, while 

 the genital aperture is situated some distance posterior to the pharynx 

 and the intestinal ceca extend to near the posterior end of the body in 

 r\ lanccolafa.
