486 PROCEEDINGS OF THE NATIONAL, MUSEUM vol.89 



Reproductive system. — As only the type specimen is available, I 

 have forborne to section it. Without sections it is impossible to fur- 

 nish any details of the reproductive system beyond those given by 

 Pearse. His figure 31B of the male copulatory apparatus appears 

 to be correct, but as regards the female apparatus I was unable to 

 see on the whole mount the two uterine glands which he figures. 



Distribution. — Crooked Island Sound, Farmdale, Fla, 



Family EURYLEPTIDAE Lang, 1884 



Definition. — Cotylea with pointed marginal tentacles, or tentacles 

 reduced or lacking ; pharynx tubular, anteriorly located, directed for- 

 ward; male apparatus single, immediately behind or beneath the 

 pharyngeal pocket ; penis with stylet ; uteri form a pair of large un- 

 branched canals along the main gut; uterine glands few, often but 

 two, or lacking. 



Genus EURYLEPTA Ehrenberg, 1831 (emend. Lang) 



Def/niti^n. — Main gut with a few (mostly three to five) branches 

 on each side, usually not anastomosing; tentacles well developed; 

 uterine glands usually one pair; mouth behind brain. 



EURYLEPTA MACULOSA Verrill, 1893 



Eurylepta maculosa Vekriul 1893, p. 495, pi. 41, figs. 2, 3. — Pearse, 1938, p. 87. — 

 Hyman, 1939a, p. 150, figs. 17, 18. 



Material. — Three whole mounts made by Pearse from specimens 

 collected by Verrill ; one marked type is intact, others labeled cotypes 

 are fragmentary. 



Form. — Elliptical or oblong, thin, changeable, with thin undulated 

 margin, 10-12 mm. long; tentacles long, bluntly pointed. 



Eyes. — For figure see Hyman, 1939a, fig. 17, p. 149. Cerebral eyes 

 in paired elongated clusters continuing as scattered eyes to anterior 

 margin; tentacular eyes borne on lower halves of anterior faces of 

 tentacles. 



Color. — Mottled brown or purplish brown on a pale yellowish or 

 flesh ground. 



Digestive tract. — Pharynx short, tubular; main gut with about 

 three pairs of lateral branches. 



Reproductive system-. — In the absence of a good specimen for 

 serial sections, I have nothing to add to my previous account and 

 figure (Hyman, 1939a, fig. 18, p. 149). 



Distribution. — Vicinity of Woods Hole, Mass., rare. 



Habits. — On piles, in mud, and among algae. 



Remarks. — This species must remain imperfectly known until well- 

 preserved material suitable foi" sectioning shall be forthcoming.
