The eyes with black pigment ; the otocysts with not very many and 

 not much calcified otokonia. No distal olfactory ganglion, as far as 

 could be seen ; no spicula in the leaves of the rhinophoria. The skin 

 as in other species ; the spicula projecting on the surface of the granu- 

 lations of the back. 



The bulbus pharyngeus about 1-1.5 mm. in length ; the sheath ot 

 the radula projecting 0.75-1.0 mm., bent upwards; the sucking-crop a 

 little larger than the bulbus itself, short-stalked ; the lip-disk as usual. 

 The tongue compressed, rather prominent, with six, eight, and nine 

 rows of teeth, also further back twenty-four, thirty-two and thirty-three 

 developed and three younger rows ; the total number of rows thus 

 being thirty-five, forty-one, forty-five. The median plates, the large 

 lateral and the (fifteen) external ones scarcely different from those of 

 the last species. 



The salivary glands rather strong, with two or three short coils fill- 

 ing the space at the sides of the oesophagus (fig. 4), white. The 

 (esophagus (fig. 4a) wide in its upper part, the rest narrow. The an- 

 teriorly proceeding part of the intestine 2.0 mm. long, the other retro- 

 ceding part <^.0 mm. long ; no biliary sac could be found either at the 

 pylorus or higher up. The liver about 9 mm. long by a breadth of 

 4.2 and a height of 4.0 mm. ; of brownish-gray color ; the anterior end 

 truncate, inclined downwards and backwards ; the anterior one-third of 

 the right side flattened for the anterior genital mass ; the posterior end 

 somewhat pointed, rounded at the point. 



The sanguineous gland whitish, covering the anterior end of the 

 bulbus pharyngeus and the foremost part of the central nervous system 

 or this last and the hinder part of the bulbus. 



The anterior genital mass about 3.5 mm. long by a breadth of 0.75 

 and a height of 1.5 mm., a very large part of it formed by the thick 

 part of the spermatoduct. The ampulla of the hermaphroditic duct 

 about 2.0 mm. long, rathf r thin, whitish. The spermatoduct long ; 

 the first part thinner, about 8.0 mm. long ; the rest making a large 

 curve, about 5.5 mm. long, about three times as thick as the first, with 

 a diameter of 0.6 mm. ; the spermatoduct proper making many coils in 

 its interior course downwards to the penis, which shows a little un- 

 armed glans in the bottom of its orifice ; in one individual the penis 

 was exserted as a conical prominence of the height of 1.0 mm. The 

 spermatotheca pyriform, about 1,0 mm. long, of grayish color; the 

 spermatocysta a little less large, spherical ; the vagina rather short. 

 The mucous gland rather small.
