tween the sucker and the posterior end of the gut, proceed ante- 

 riorly and after skirting the uteri sweep inward to fuse in the mid 

 line. The canal thus formed immediately plunges through the 

 spherical seminal vesicle and as a slender ejaculatory duct directs 

 its course to the penis. The granular gland is oval, of moderate 

 size, and opens into the ejaculatory duct near the penis. 



The ovaries are dorsal. The uteri extend posteriorly to the same 

 distance as the main gut, behind which they fuse to form a short 

 median branch. Anteriorly they extend between the gut and the 

 vasa deferentia, and converge to open in the mid line a short distance 

 posterior to the seminal vesicle. 



Euryleptodes phyllulus sp. nov. 



This species is represented by several individuals taken on the 

 southern shore of Monterey Bay. The largest specimen is elliptical 

 in outline (PI. XVI, fig. 33) and measures 28 mm. in length by 18 mm. 

 in width. Color notes are wanting. The sucker is slightly anterior 

 to the centre of the body. The mouth is about one-eighth the 

 length of the body from the anterior end near the apex of the pharyn- 

 geal pocket. The penis is directed forward. 

 The tentacles (PI. XVI, fig. 33) are fleshy 

 outgrowths of the anterior margin of the 

 body, extending posteriorly as far as the 

 brain. On and between the tentacles are 

 medium-sized eyes (text fig. 12) which 

 assume no definite arrangement, and they 

 also occur over the brain in a triangular 

 group, of about 150 ocelli, which are faintly 

 divisible into two clusters. 



The mouth (PL XVI, fig. 33) opens into 

 the roughly triangular-shaped pharynx from 

 which the main gut proceeds posteriorly, 

 giving rise to about seven pairs of intestinal 

 branches. These last-named organs are 

 often swollen at their bases, but more distally gradually decrease in 

 caliber and form an elaborately anastomosing system. 



The brain is situated immediately in front of the pharyngeal 

 pocket, but the other details of the nervous system are well-nigh 

 invisible in surface mounts. 



The testes (PI. XVI, fig. 33) are liberally distributed over the 

 ral half of the animal, but no trace has been seen of the con- 

 sperm capillaries. The vasa deferentia extend posteriorly
