I40 DISCOVERY REPORTS 



digitiform process, a laciniated posterior ventral lamella with the edge cut into about 

 five processes and a small pointed anterior ventral lamella. There is also a scale-like 

 process behind the ventral cirrus. 



Nephthys macrura, Schmarda. 



Fauvel, 1916, p. 436, pi. viii, figs. 1-3, with synonymy. 

 Monro, 1930, p. m. 

 Occurrence. St. 123 (4); 144(4); 164(6 juv.); 190(1); 366(i2);368(i);4s6(io);458(numerous); 

 474 (3); 599 (i); WS 212 (5); WS 228 (i); WS 236 (i); WS 244 (i); WS 772 (i); WS 773 (5); 

 WS774(i);WS783(2). 



Specific characters. Up to about 200 mm. in length. There are two groups of 

 minute eye-spots at the base of the prostomium. The proboscis has 22 terminal 

 papillae and 14 rows of papillae, each of which forks at the base into two or more 

 divergent rows of minute papillae. The feet are very variable. There is always a rounded 

 upper dorsal lamella, a lower dorsal lamella gathered to a point at its apex, and a lan- 

 ceolate ventral lamella. There are no "lyre" bristles. 



St. 458 yielded a superb specimen measuring 230 mm. in length from the tip of its 

 extruded proboscis by 15 mm. in breadth without the feet, and with a thickness of 

 II mm. The body-colour is a fine iridescent purple. 



Nephthys squamosa, Ehlers ? 



Ehlers, 1887, p. 128, pi. xxxvii, figs. 7-10. 

 Occurrence. St. WS 808 (12). 



Specific characters. About a dozen specimens, mostly small fragments. Among 

 them are two or three fully grown examples, the largest of which measures 180 mm. by 

 7 mm. without the feet. None has the proboscis everted, and by dissection I can only 

 discover that there are about 20 rows of papillae on the proboscis. Ehlers gives 22 rows 

 of papillae and a single, large anterior papilla both dorsally and ventrally. The feet seem 

 to correspond to Ehlers' account. There are in the dorsal ramus a rounded, scale-like, 

 upper posterior lamella, a long, pointed, lanceolate, lower posterior lamella, and a small 

 leaf-like branchial cirrus; the ventral ramus has a small tongue-shaped process lying 

 above the bristles and a long, leaf-shaped, pointed, ventral posterior lamella. 



Remarks. This species is known from the tropical belt on both sides of the Atlantic, 

 but I am somewhat sceptical of its occurrence as far south as the present locality. 

 Unfortunately, I have no material other than two small anterior fragments from 

 Gorgona Island in the Pacific, which I myself rather doubtfully assigned to squamosa, 

 with which to compare the present specimens. Their feet agree well enough with 

 Ehlers' account, but I have not been able to discover the exact arrangement of the 

 papillae on the proboscis. Their precise attribution must for the present remain 

 doubtful.
