Plate xl, figure 1. 



The only specimen that I have seen was small and immature. 

 The reproductive organs were not developed. The body of this 

 was very thin, obovate, with a broadly rounded anterior and a nar- 

 rowed posterior end, when creeping. The tentacles were distant 

 from the front margin, clavate, each with a very distinct ocellus 

 in the rounded tip. The ocelli formed two linear divergent groups 

 of about ten each, commencing between or a little behind the ten- 

 tacles and extending much beyond them anteriorly. The pharynx 

 and stomach were not well defined, but the stomach appeared to 

 have rather numerous (at least seven or eight) main lateral branches, 

 which were much divided distally, and appeared to branch dichoto- 

 mously. 



The color, to the naked eye, appears bright red with pale margins; 

 when much enlarged the bright carmine red is seen to form irreg- 

 ular radiating and branched lines, corresponding to the branches of 

 the stomach, while the narrow intervening spaces, the gastric region, 

 the cerebral area, the tentacles, and the margins are translucent 

 whitish. The margin is, however, covered with small pale yellow 

 spots. 



Length of the young specimen described and figured, in life, 

 4*5"'™; greatest breadth r5"'"\ According to Girard, this species 

 becomes l"o inches long; -5 wide.

 bottom, Sept. 4, 1882. Charleston, S. C. (Girard). 



Family, Leptoplanid.e Stimp., 1857. 



Body bi'oad, flat, usually thin or foliaceous. Tentacles none. 

 Mouth ventral, near the center of the body. Pharynx large, lobed 

 or plicated. The main lateral branches of the stomach vary in 

 number ; the distal branches often anastomose freely. Ocelli nu-
