Asa comparison of numbers of species, I may refer to the “Shells 
of Antioch and vicinity,’ found by Mr. Carlton and others in the 
east end of Contra Costa County, twenty-five species and varieties. 
_ In Clear Lake I only found eleven; in Sierra Nevada, near latitude 
39°, thirteen are known; and Mr. Raymond found eleven near lati- 
tude 38°, besides eight in San Jose reservoir, the same number 
known from Santa Cruz County. 
{ Nore.—I have ascertained that the name CALYCULINA has been 
given to the same group to which in Proc. Cal. Acad. ser. 2, iii, 82, 
I applied the name PRIMELLA. The latter is therefore a synonym, 
unless Sphzrium, for which, however, there seem to be other 
available synonyms, should be dropped.—J. G. C.]
