This list, of about 133 species from the northern and 32S from the 

 southern fauna (nearly twice as large as that sent by Dr. Ciould and printed 

 in the first Eeport, and yet not containing several species there quoted), is an 

 instructive instance of what may be accomplished in about three-quarters of 

 a year, simply by picking up shore-shells. It contains about 48 species in 

 the northern and 22 in the soutliern faunas not previously described. 



Besides the recent shells, Col. Jewett brought home a very interesting 

 series of Pliocene fossils from the neighbourhood of Sta. Barbara. Almost all 

 of them are species known to inhabit neighbouring seas, and are chietiy 

 northern forms. Of some no recent specimens have yet been found in such 

 perfect condition. Tlie following is a list of the species, which is of the more 

 value as they have not been intermixed with those of any otlier locality, and 

 the spot does not seem to have been discovered by any succeeding geological 

 explorer. It was two miles from the coast, and 150 feet high.
