This species is abundant in the bay of San Diego and in the harbor 
of San Pedro. At San Diego we obtained in the winter, a very large 
number of immature individuals. At Wilmington we secured one speci- 
men nearly adult, and saw numerous others swimming about near the 
surface in the muddy waters of the harbor. 
We have named this species for Miss Rosa Smith, of San Diego, who 
has given much attention to ichthyology, and to whom the National 
Museum is indebted for many specimens of San Diego fishes.
