Pedro. It reaches a length of twelve to twenty inches and a weight of 
about five pounds. It has been taken at Monterey, but is common only 
from San Pedro southward to Magdalena Bay. So far as known to us, it 
agrees in habits and value with the preceeding. 
The Spotted Cabrilla, Serrcums maculofasciatus , receives the same 
names, “ Rock Bass ” and “ Cabrilla,” as others. It agrees with the pre¬ 
ceeding in value, distribution, and habits, so far as is known, but is rather 
smaller in size. It is an excellent food-fish, and from its great abundance 
about San Diego it may become of considerable economic importance. 
Its range extends southward to Mazatlan, it being one of the very few 
California fishes which extend their range to the south of the Tropic of 
Cancer.
