Cynthia villosa, Stimp.* PI. XII., figs. 7 — 11. 



This species was very briefly described in 1864 by 

 Stimpson from specimens obtained off Lummi Island and 

 also at Port Townsend in Puget Sound, the exact locality 

 where I dredged the present specimens. Although 

 Stimpson does not sufficiently describe the species, still 

 his account of the appearance agrees so well w 7 ith my 

 specimens, that I have no hesitation in referring them to 

 his species villosa, which I take this opportunity of re- 

 describing. Stimpson' s description was as follows : — 



" Of similar size, and allied to the Cynthia echinata of the 

 North Atlantic, of which this is the analogue or repre- 

 sentative species on the west coast. It is, however, 

 easily to be distinguished from that species by the 

 character of the villosity or short hair-like processes with 

 which the test is covered. These are shorter, more 

 numerous than in C. echinata, and not provided with 

 radiating hairs at the summit, being simply tapering to a 

 fine extremity, and sparsely pubescent on their sides. 



" The base of attachment in this species is very small, and 

 the test at that point is produced into a peduncle, w T hich 

 is sometimes as long as the body is thick. This peduncle 

 is, however, entirely similar to the test in character, and 

 not at all like that of Boltenia. Our largest specimen 

 is about 0'6 inch in diameter. 



" Port Townsend, . . and N.W. end of Lummi Island, 

 &c." 



The species has apparently not been found since 

 Stimpson's time, unless the spiny form which Traustedt 

 described from the Kara Sea in 1886, under the name of 

 Cynthia echinata, can be referred to the present species. 

 They certainly agree in many points, and Traustedt's 

 species is nearer to C. villosa than to the true C. echinata
