Under this name Garman has described from two specimens a small rattlesnake from Cerros Island. It seems very closely related to C. atrox.
Natividad Island.
I have seen only one lizard from this island.
1. Uta stansburiana Baird & Girard.
A single specimen (Cal. Acad. Sci. No. 4705) of this Uta was secured on Natividad by Mr. R. H. Beck, May 9, 1903.
Magdalena Island.
I have elsewhere recorded six species of lizards from this island. It is necessary only to mention them here. The specimens are in the collection of the Academy.
1. Dipsosaurus dorsalis Baird & Girard.
