DIAGNOSES OF NEW SPECIES OF MOLLUSKS FROM 

 THE SANTA BARBARA CHANNEL, CALIFORNIA, 



BY WILLIAM HEALEY.DALK 



Daring the past summer Mr. Herbert N. Lowe and Mr. John 

 H. Paine, with the aid of a gasoline launch, did some dredging 

 in the Santa Barbara Channel near . Avalon, Catalina Island, 

 The depth of water was from 40 to 60 fathoms. 



The result of this work, by two enthusiastic young -collectors* 

 has been very interesting, two genera not before known to in 

 habit the coast having been discovered, represented by two 

 species, both new, one of which, Metzyeria californica, has al 

 ready been described elsewhere by the writer. 



The following species, from among those sent to the writer 

 for identification, appear to be new, and diagnoses of them are 

 now provided. The presence of so many novelties gives some 

 idea of the richness of the molluscan fauna of this region, and 

 indicates that many more forms probably remain to be discov 

 ered in the same vicinity. When not otherwise stated the 

 locality is as above mentioned, and all except Mitra dolor osa^ 

 are represented in the collection of the gentlemen named. 



Mrs. Lydia Emerson Fancher and Mrs. Lillie J. Sawin as 

 sisted in the search for mollusks and at the request of Mr. Paine 

 two of the species have been named in honor of these ladies.
