triangular in cross section; it has transverse rows of sharp spinelets 

 (figs. 11, 13) that extend across the width of the appendage fig. 12). 



G. solitaria has remained incompletely known and enigmatical so 

 that comparison with other species of the genus was difficult. The type 

 collection on which the original description was based, is not known to 

 exist. The species was originally briefly described as a Goniada; Arwid- 

 sson (1899, p. 49) correctly surmised it to be a Glycinde, but erron- 

 eousely referred Goniadella gracilis (see above) to it. The first 25 seg- 

 ments were described as uniramous (24 segments by my count). The 

 setal lobes were described as "anterior long and narrow, posterior short 

 and broad." The setae were said to be of only one kind; this referred 

 probably to the composite, neuropodial setae; I assume that the acicular 

 notosetae were designated acicula. 



G. solitaria may be characterized thus: The parapodial change 

 occurs at segment 25; the prostomium is 9-annulate and has 2 pairs 

 of eyes; paragnaths consist of a pair of ventral macrognaths and a 

 dorsal arc of about 10 micrognaths; a ventral arc is lacking. Probos- 

 cidial organs of areas IV and V are unique. Anterior parapodia have 

 larger dorsal and ventral cirri and subequal long setal lobes; posterior 

 parapodia have smaller dorsal and ventral cirri and the presetal neuro- 

 podial lobe is much longer than its corresponding postsetal one. Dorsal 

 cirri are incised near the tip. 



Distribution. — G. solitaria (Webster) was originally described from 

 New Jersey, at low water line. The present materials come from 

 Chesapeake Bay, Maryland and Beaufort, North Carolina, from sandy 

 shoals at low tide line. 



Glycinde multidens Miiller 



Muller, 1858, p. 214, figs. 4-6; Augener, 1918, p. 398. 



This species is the type of the genus Glycinde, but it remains very 

 poorly known in several important respects. It originates in Brazil. 

 Augener (1918, pp. 398-399, pi. 7, fig. 196) reexamined the type 

 collection and enhanced its description, but the structure of parapodial 

 lobes and proboscidial parts still remains obscure. 



According to the revision, G. multidens has anterior parapodia in 

 which postsetal lobes are up to twice as long as the presetal ones. In 

 biramous parapodia the postsetal lobe is at first longer than the presetal 

 one, but farther back both lobes are about equally long; here each con- 

 sists of a broad base that terminates in a point. In median, transitional 

 parapodia there is a small notopodial papilla that is said to be ventro- 

 posterior in position.
