333 Chioaera leonina 
Tryon gives this name as Chiorhaea according to Yates; ap- 
pears in Cooper’s list as Chioraera; Yates spells the name as 
Chioraea leontina, and says Gould’s original description and 
Cooper’s agree. Yates also cites J. W. Fewkes, Essex Inst. bull. 
xxi, 1889. One specimen was dredged in the Santa Barbara chan- 
nel at 20 fathoms by Dr. Cooper. 
Animal wholly translucent, pale yellow, the variations marked 
only by a darker shade; form of head nearly conicle, the apex 
anterior, forming an angular roof above the anal opening; bran- 
chia processes 5 on each side, larger than represented in Gould’s 
figure (Mollusks and shells, U. S. Expl. Exped.), imbricated and 
decumbent; length 2.75, height 1 inch. 
Type locality: Vancouver Island, British Columbia.
