NO. 1 HARTMAN : GONIADIDAE, GLYCERIDAE, NEPHTYIDAE 111 



Interramal cirri are first present from segment 4. This species is 

 chiefly characterized for the strongly imbricated superior lamellae of 

 notopodia. In this respect it resembles N. imbricata Grube (1856, p. 

 168) from Valparaiso, Chile, but the latter is too incompletely known 

 for certain identification. 



Three small, presumably juvenile individuals earlier reported as 

 AT", assimilis (Hartman, 1940, p. 239) from stations 495-36 and 770-38, 

 are referred to N. squamosa, although the parapodial lobes are not 

 imbricated as is typical for adult or larger specimens. Other characters, 

 notably the early origin and large size of interramal cirri and the setal 

 structures are those of N. squamosa. 



Distribution. — This occurs on both sides of tropical America and 

 tropical west Africa; it is subintertidal to 120 fms.

Collection. — Gullmar Fjord, Sweden, dredged (1). 



Interramal cirri are first present from segment 8 to 10; they are 

 minute at first but gradually increase in size and come to be large and 

 foliaceous; on the last 25 to 30 segments they are again small or nearly 

 absent. Postacicular setae are more distinctly toothed at the cutting edge 

 than are similar ones in N. phyllobranchia (below) with which this is 

 nearly allied, if not actually identical. Furcate setae are believed to be 

 absent. 



The single specimen in the collections was a gift from Dr. Gunnar 

 Gustafson, to whom thanks are extended. 



Distribution. — North Atlantic Ocean in moderate to shallow depths. 



Nephtys phyllobranchia Mcintosh

Collection. — Off Delaware in 1105 fms (1). 



The prostomium lacks eyespots. Nuchal organs are moderately con- 

 spicuous. The proboscis has 22 rows of papillae distally and as many 

 subterminally ; there is none distinctly middorsal. The proximal sur- 

 face is smooth. Interramal cirri are first present though very small, from 

 about segment 13; they increase in size gradually and are large, strongly 

 foliaceous by segment 35. They decrease in size thereafter so that by 

 segment 40 or somewhat later they are absent. Postacicular setae are 

 faintly serrated at the cutting edge. Furcate setae have not been iden- 

 tified.
