Autodax lugubris farallonensis, Batrachoseps pacificus, Uta martinensis, Uta stellata, Uta auriculata, Uta clarionensis, Sceloporus becki, Phrynosoma cerroense, Xantusia riversiana, Cnemidophorus multiscutatus, Cnemidophorus labialis, Bascanion anthonyi, Bascanion laterale fuliginosum, Crotalus exsul. Although the evidence is thus too meager to enable one to speak positively, it would seem that the probable faunal relationship is about as follows: TRANSITION ZONE. _Pacific Fauna:_ Farallon Islands. UPPER AUSTRAL ZONE. _Californian Fauna:_ San Miguel, Santa Rosa, Santa Cruz, Ana Capa. _San Diegan Fauna:_ San Nicolas, Santa Barbara, Santa Catalina, San Clemente. Los Coronados, San Martin. Perhaps San Benito, Cerros, Natividad. LOWER AUSTRAL ZONE. Perhaps San Benito, Cerros, Natividad. Magdalena, Santa Margarita. Socorro, Clarion. SOUTH FARALLON ISLAND. No reptiles have been found on the Farallon Islands and it is probable that none occur there. The amphibians are represented on South Farallon Island by a salamander which has been regarded as identical with _Autodax lugubris_ Hallowell. Specimens from this island, however, are much more profusely spotted or blotched with yellow than is the mainland form of this species. In examining series of specimens one finds a few individuals from the mainland as heavily spotted as some of the Farallon specimens, but the average difference seems constant and the extremes are very dissimilar. I therefore propose that the Farallon Island form be called 1. =Autodax lugubris farallonensis= subsp. nov. PLATE II. _Anaides lugubris_ YARROW, Bull. U. S. Nat.
