60 PROCEEDINGS OF THE CALIFORNIA 



rior tentacles two, above the mouth, dorsal tentacles club-shaped, a white streak 

 extending from the median line between them to the mouth. Length nearly an 

 inch. 



One specimen dredged on a rocky bottom, in a depth of 16 fathoms, a mile 

 from the shore at Santa Barbara. 



Although small, its characters are too different from those of our other spe- 

 cies, when of the same size, to allow us to consider it the young of any of them. 



Flabellina Cuvier, 1830. 

 F. opalescens Cooper. 



Syn. ^Eolis, (Flabellina?) opalescens, Cooper— Proc. Cal. Acad. II, 1862, 

 p. 205. 



9 JFhis species, dredged from the same locality as the last, presented exactly the 

 «ame characters as the original specimens from San Diego. I also found a few 

 of them on the rocky shore of Santa Barbara Island, differing only in having 

 the branchial olive, tipped with white. 



Phidania Gray, 1850. 

 P. iodinea, Cooper— Syn. ^Eolis (Phidania?), iodinea, Cooper, loc. cit. sup. 

 I found one of this species on the beach at Santa Barbara, agreeing exactly 

 with those from San Diego. 



Chior^era Gould, 1855. 

 C. leonina (?) Gould — Molluscs and Shells, U. S. Expl. Exped. 



Wholly translucent, pale yellow, the variations marked only by a darker 

 shade. Form of head nearly conical, the apex anterior, forming an angular 

 roof above the oral opening. Branchial processes five on each side, larger than 

 represented in Gould's figure, imbricated and decumbent. Length 2.75, height 

 1 inch. Otherwise as in the description and figure of Gould's specimen. 



A siugle specimen dredged in 20 fathoms off Santa Barbara, May 15th, dif- 

 fers in the points above mentioned from the northern animal, but being much 

 smaller, the differences may arise from immaturity, and I have therefore pre- 

 ferred to retain the same name for it. 



The single specimen which formed the type of the genus was dredged in 

 Puget Sound, was over five inches long and of various bright colors, the head 

 subglobose, higher than oral opening, branchiae in six pairs, comparatively 

 smaller and erect, all of which differences may have arisen from more perfect 

 development, and from having been observed under more favorable conditions. 



From its rarity on our southern coast we may expect to find it more abund- 

 ant northward. 



Dr. Kellogg read a paper describing a new species of Alsine, 

 collected by Mr. Bolander, in the swamp near Mission and Howard 

 and Seventh and Eighth Streets, San Francisco.
