670 A. M Verrill — Turhellarla^ Wemertina, and 



acute, hooks, arranged closely side by side in each row ; these are 

 followed by close circular rows of minute rounded granules, which 

 increase in size proximally. 



The integument is firm, but somewhat translucent, and. contains 

 about 30 principal muscular bands, with irregular smaller ones 

 between them. 



This species appears to be the same as Sipunculus granulatus 

 Pourt., 1851, from Florida, but it is probably distinct from the 

 European Physcosoma granidatimi (Leuck.). 



It is evidently very closely related to, and perhaps identical with, 

 P. Puntarenm (CErst & Gr,, 1858), described from St. Croix. 



Fhascolosoma cylindratum Kef. 



The second species is about 40™'" long and 3-4™°^ in diameter, 

 translucent whitish, tapering posteriorly, and almost perfectly 

 smooth, but with microscopic pale granules posteriorly and with 

 rows of minute, obtuse hooks on the anterior part of the proboscis ; 

 tentacles small, papilliform. This was more abundant in shell-sand at 

 low-tide and under stones. The original type was from Bermuda. 



Aspidosiphon spinulosiun, sp. no v. 



A third species, belonging to Aspidosiphon, was found in dead 

 corals. The body is about 20™" long; the probosis 24'"™, as pre- 

 served, and slender. The posterior shield is round, convex, light 

 brown, with many radii; the siphonal shield is round, dark brown, 

 covered with angular chitinous grains. The body is granulated with 

 minute chitinous points close to the posterior end ; the proboscis is 

 covered above with minute black, sharp, recurved spinules, becoming 

 fewer and smaller beneath. The large retractor muscles are attached 

 far back. 



Grolfingia elongata, sp. nov. 



The fourth species is, perhaps, a Golfingia. Its body is slender, 

 about 20"^"" long, 2'""^ in diameter ; the extended probosis is 15-20'"™ 

 long and about 1'"™ in diameter. Color, yellowish brown. The horny 

 ring at the base of the proboscis is dark brown, wide, and gibbous 

 dorsally, much narrower beneath, tapered anteriorly, covered with 

 strong longitudinal and divergent ridges. The posterior shield is 

 round, conical, with fine radial lines. The proboscis is rugulose, 

 wrinkled, covered with minute, sharp, erect spinules, arranged with- 

 out order. It is darker brown than the body, which is Avhite poste- 

 riorly and smooth for about ^ of its length.
