This list, of about 13.3 species from the northern and 328 from the 

 Bouthorn fauna (nearly twice as large as that sent by Dr. (loiild and printed 

 in the first Report, and yet not cintaining several species there (juoted), is an 

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

 a year, simply by picking up shore-shells. It contains about 4^ species in 

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



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

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

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

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

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

 value as they have not been intermixed with those of any other localitj', 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.
