130 BULLETIN OF THE BUREAU OF FISHERIES. 



Sir Charles Eliot (Cockerell and Eliot, Notes on a Collection of Californian Nudibranchs, Journal 

 of Malacology, xii, 1905, p. 37), comes to the well-founded conclusion that Ch. unirersUalis Cockcrcll 

 is identical with the previously-described Ch. californiemtis Bergh. The latter species is stated by Oall 

 to have been taken at Monterey. It must be of extremely rare occurrence, as 1 have never fouml it 

 in twelve years' collecting at varying times of the year.

Family H. 1)0R1()PSI1)II).€. 



Body nearly always soft, its form almost exactly as in true Dorididee. Oral a].eitiiri' pore like,

 fleck. General color of animal a rich yellow (pi. xxii, fig. 3), the foot and under side of mantle margin 

 slightly lighter in color, the rhinophores darker, the branchial plumes yellowish white. In alcohol
