44 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 15 



In so far as I know, this remains the only species in the family 

 that can be referred to the genus. 



Distribution. — Goniadella gracilis is known from Gays Head, Mass- 

 achusetts in 19 fms, off Cape Cod, Massachusetts, in intertidal zones, 

 and off Rhode Island, in 1 1 % fms. 



Genus Glycinde Miiller, 1858 

 Type G. multidens Miiller 



Includes Eone Malmgren, 1866 and Epicaste Kinberg, 1866. 



The prostomium is long, conical and more or less strongly annu- 

 lated ; it terminates in front in 4 small, biarticulated antennae. There 

 are usually eyes in the basal ring or also in the distal one. The pro- 

 boscis is long and cylindrical ; distally it is provided with a row of soft, 

 terminal papillae within which are the paragnaths. The latter include 

 a pair of large, dentate macrognaths ventrally or ventrolaterally, with 

 the largest teeth on the dorsal end, and smaller micrognaths. In most 

 known species of the genus, the micrognaths are limited to a dorsal arc, 

 but there may be also a short, ventral arc. The proximal portion of the 

 proboscis is more or less completely covered with longitudinal series of 

 horny yellow, spinous processes or proboscidial organs. They are ar- 

 ranged in patterns so that individual ones may be recognized when 

 detached (see terminology below). There are no chevrons; the pieces 

 numbered IV (textfig. 2) are believed to be homologous. 



Anterior parapodia are uniramous and provided with only composite 

 spinigerous setae in addition to single acicula. The middle body region 

 is transitional, with notopodia weakly developed. A long, posterior 

 region has well developed biramous parapodia in which both notopodia 

 and neuropodia are noticeably larger than those in front. Notopodia 

 are provided with single acicula and few simple setae; they are usually 

 hooked at the tip and have a long, pointed hood. Neuropodial setae 

 resemble those in front; they are much like those in species of Goniada 

 (see above). 



The organs of the proboscis in Glycinde are of special interest be- 

 cause of their remarkable diversity and striking patterns. The only ex- 

 tensive account of these parts, of which I am aware, that explains and 

 illustrates the details and distribution of these processes, is that by Levin- 

 sen (1893, p. 332, pi. 1, figs. 1-6) based on Glycinde nordmanni (Malm- 

 gren). The complexity of their arrangement and the regularity of their 

 occurrence is clearly indicated. However, there is an unfortunate con- 

 fusion of terms and errors in orientation of dorsal for ventral parts 

 throughout Levinsen's description and figures. Also, the distal para-
