supports very deeply forked, the two slender 

 prongs being almost separate. Parapodia with 

 two presetal lobes with the superior one slightly 

 smaller. Either a single emarginate posterior 

 lip or two low, rounded lobes. No branchiae. 



R(C(ii-(_ls. — Seven specimens from 6.5-120 m 

 off Beaufort (20, *) This is a new record for 

 the Atlantic coast of the United States. 



Distribution. — Cosmopolitan in temperate 

 and trojiical seas; 5 to over 500 m. 



Glycera asynimetrica New Species 



FijJ'ui'e Gd-K' 



Holotype. — USNM 4.3148; three paratypes, 

 USNM 43149. 



Description. — Body rounded in section, ta- 

 pered at extremities and up to 50 mm long. 

 Prostomium elongate and tapered with about 

 15 indistinct rings but no visible eyes. Pro- 

 boscis covered with numerous long smooth 

 papillae and a few ovoid ones (Figure 6e). Jaw 

 supports (Figure 6d) formed of two unequal 

 rami quite separate except at point of contact 

 with jaw. Shorter ramus expanded basally, 

 longer ramus more slender. Parapodia without 

 gills. All feet with two digitiform presetal lobes, 

 the inferior one slightly longer. Postsetal lobes 



changing along the body; first 20 feet with a 

 single truncate postsetal lobe (Figure 6f), pos- 

 terior feet with a small posterodorsal digitiform 

 lobe above a low rounded postsetal lobe (Figure 

 6g); middle feet changing from anterior to 

 posterior form. 



Rrnnn'ks. — The posterodorsal digitiform lobe 

 of the posterior feet is in the same position as 

 the gill of Gh/cera coiiroliita. but it is definitely 

 not a gill and is never as long as the presetal 

 lobes. Apart from this queer asymmetrical lobe 

 and rather shorter proboscideal papillae, this 

 species resembles G. tesselatn. In particular the 

 form of the jaw supports is very similar. I am 

 indebted to Dr. Pettibone for informing me that 

 this species resembles G. spin/ rabi'a iiclia 

 Schmarda from Jamaica the type of which was 

 redescribed by Augener, (1925: 29, Fig. 1). The 

 jaw supports, proboscideal pai)illae and gen- 

 eral appearance of the feet is similar. However 

 Augener describes a nonretractile gill arising 

 from the dorsal edge of the 30th and later feet 

 which becomes much longer and stouter than 

 the presetal lobes. It is possible, but unlikely, 

 that this is the same as the "small posterodor- 

 sal digitiform lobe" described above, which as 

 stated, is definitely not a gill. 



Records. — Four specimens off Beaufort in 

 20 m (*).
