This list, of about 133 species from the northern and 328 from the 
southern fauna (nearly twice as large as that sent by Dr. Gould and printed 
in the first Report, 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 southern 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 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 locality, and 
the spot does not seem to have been discovered by any succeeding geological 
explorer.
