with rather strong longitudinal folds; the pylorus (fig. 17) in the 

 neighborhood of the cardia. The intestine advancing from the stom- 

 ach to the fore-end (fig. 176) of the liver, in this part about 10.0 mm. 

 long ; forming a knee and retrograding to the anal nipple in a length 

 of 23.0 mm. The contents of the stomach were indeterminable animal 

 matter, mixed with some diatomacea;. 



The liver 20.0 mm. long by a height of 10.0 mm. and a breadth of 

 about 12.0 mm. ; the posterior end rounded ; a little more than the an- 

 terior half of the under side obliquely flattened (by the anterior genital 

 mass) showing the cardiac end of the a?5ophagus and the root of the 

 hermaphroditic duct. On the anterior part of the upper surface is a 

 cleft for the stomach and for the biliary sac ; the color of the surface 

 and of the substance of the liver is grayish-yellow. The biliary sac 

 (fig. 17c) lying before the stomach, on the right side of the intestine, 

 large fas the stomach), somewhat flattened, grayish, of rounded out- 

 line and about 4.5 mm. largest diameter ; the contents, as in the 

 stomach. 



The heart as usual. The sanguineous gland whitish, entirely cover- 

 ing the nervous system, about G.O mm. long, by a breadth of 4.5 and a 

 height of only 1.0 mm. 



The hermaphroditic gland yolk-yellow, covering the upper side of 

 the liver with a thick layer ; in its lobes large o'jgene cells and masses 

 of zoJsperms. The anterior genital mass large, about 14.0 mm. long 

 by a breadth of 9.0 and a height of 11.0 mm., flattened and a little ex- 

 cavated on the left side, with an excavation on the fore side, the right 

 side very convex. The hermaphroditic duct whitish, rather thin 

 (diameter about 0.75-1.0 mm.), passing straight over the left side of 

 the genital mass to its anterior end, without formation of any (distinct) 

 ampulla. The first part of the spermatoduct whitish, forming several 

 long windings on the upper part of the forepart of the mass and pass- 

 ing into the yellowish (PI. VI, fig. 18a) continuation ; this, with its 

 numerous coils, forms a large flattened layer on the fore-end of the 

 right side of the mass ; it then rather suddenly passes into a much 

 thinner whitish continuation (fig. I8b) about 6 mm. long, that slopes 

 (fig. 18c) into the penis, which (retracted) was lying on the lowest 

 anterior part of the right side of the mass. The penis was cylindrical, 

 of the length of 11.0 mm. by a diameter of 1.5 mm. ; the truncated, 

 cylindrical, yellowish (under a magnifier nodulous) glans forming 

 (PL V, fig. 13, 14) a prominence of the length of nearly 1.0 mm. in 

 the vestibulum. This glans was partly covered on the outer side
