tions, forming lagoons and creeks. A small group of picturesque rocks 
atfords the only protection to the bay on its western side at a distance 
of 10 tfniles from Ensenada. 
Having a low tide during our stay, the rock pools were thoroughly 
searched with dip-nets, and many heavy stones overturned. 
At Punta Banda, on the southern shore of the bay, lives George Tan- 
nahill, a Scottish fisherman, who has built a small hut of water-worn 
bowlders on the shingle beach, where he spends, with his family, a few 
months of the year “fishing for a pastime,” as he told me. He had on 
hand two species of fishes (T'rochocopus pulcher and Serranus clathratus). 
He formerly dried the ‘‘red-fish” for exportation, but now no regular 
fishing is done anywhere on the bay. He gave me the cortmon names 
of thirteen species, which may be referred to the species in this list 
which are marked with an asterisk, and whjch are accompanied by the 
common names used by Mr. Tannahill.
