This species is most closely related to E. horealis Oersted and E. 

 longisetosa Horst, but is distinguished from both by numerous charac- 

 ters. It was taken from the Gulf of Georgia to Behm canal, in depths 

 ranging from 18 to 134 fathoms. 



Euphrosyne liortensis sp. nov. Plate XXXIV, figs. 13 to 16. 



Length about 22 mm., width 7 mm., numl^er of segments 35 to 38. 

 The general aspect of the dorsum of this species reminds one of a well- 

 kept garden with a central avenue from which diverge parallel rows of 

 plants with aisles between. 



The body has the usual depressed form, flat below, slightly arched 

 above ; in contraction the two ends are rounded nearly equally. Below 

 the segments are strongly marked ; abo^•e they are more ol)scured l:>y 

 the gills and setse except in the median space which ecpials about ^ of the 

 total width and in which each segment is divided into a posterior me- 

 dian and a pair of anterior lateral areas. The caruncle is long and 

 narrow, reaching from II to the posterior margin of \l, with a pair of 

 pronounced lateral longitudinal grooves and a narrow but distinct 

 median ridge or crest, the posterior end of which is free. At the end 

 of the caruncle are the conspicuous, black, dorsal eyes, sometimes two 

 pairs, of which the anterior are the larger, sometimes a single pair of 

 slongated form, or occasionally a single one on one side and two on the 

 other. A median tentacle arises from between the eyes and has a 

 length of barely 1^ times the width of the caruncle; it is 2-jointed, the 

 basal joint stout, the terminal filamentous and somewhat shorter. On 

 the ventral aspect of the prostomial area between the first pair of 

 forwardly directly parapodia is a pair of black ventral eyes, which are 

 frequently coalesced into a single median one flanked by a pair of minute 

 tentacles. The palpi are continuous anteriorly with somites I and II, 

 and extend caudally as a pair of prominent rounded lobes Avhich end 

 freely at IV, covering the small mouth, which is bounded behind by IV 

 and V. A faint neural groove follows the median ventral line to the 

 pygidium, which bears a pair of short, thick, fleshy, grooved, subanal 

 cirri. 



The notopodia are completely coalesced with the dorsal surface and 

 their setigerous areas cover most of the back except the median region. 

 The neuropodia project from the sides of the somites, and between them 

 and the notopodia are narrow oblique smooth areas without seta\, into 

 which the lower end of the series of branchia bend forward. All three 

 cirri are rather stout and conical. The dorsal is situated at the dorsal 

 end of the branchiferous line, the middle anterior to the latter and about
