NOTES ON A COLLECTION OF CALIFORNIAN 

 NUDIBRANCHS. 



By Professor T. D. A, COCKERELL and SIR C. ELIOT, K.C.M.G. 



(Plates vii and viii.) 



The animals described below were collected by Mr. Cockerell at San 

 Pedro and La JoUa in South California (about 33° S). He also supplied 

 the coloured sketches and accounts of the living animals which added much 

 to the value of the present paper, and I have, therefore, coupled his name 

 with mine as one of the authors, since it was not always possible to quote his 

 descriptions as they generally take the form of a few words written at the 

 sides of rough sketches. But he is not responsible for the descriptions of 

 the preserved specimens or for any of the views expressed in the following 

 pages. The new specific names are due to him, the generic names to me. 

 Some of the specimens had been deposited in the British Museum, and I 

 have to thank Mr. E. A. Smith for kindly allowing me to examine them. 

 The collection contains the following species : — 



1 . Tritonia palmeri, Cooper. 



2. Archidoris montereyensis juv. (Cooper). 



3. Cadlina flavo?naculafa, MacFarland. 



4. G. marginata, MacFarland.
