The three specimens of _Gerrhonotus_ from San Martin Island are very similar to the species now known as _G. scincicauda_, but are much rougher than specimens from central and northern California. Reëxamination of the Californian material at hand shows that the San Martin Island form is found throughout the San Diegan Fauna and the western slope of the southern Sierra Nevada below the range of _G. palmeri_. It may be distinguished from its more northern relative by the following synopsis of characters:-- a.--Temporals smooth; scales on arm smooth; scales on forearm smooth or weakly keeled; lateral caudals five scales behind anus smooth 6-9 rows from inferior mid-caudal line. =G. scincicauda.= a.^{2}--Temporals keeled; scales on arm keeled; scales on forearm keeled; lateral caudals 5 scales behind anus smooth only 4-5 rows from inferior mid-caudal line. =G. s. ignavus.= =3.

A young gopher snake taken on San Martin Island by Dr. Streets is still in the National Museum. The Academy has an adult specimen (No. 4702) collected there by Mr. Beck, May 3, 1903. SAN BENITO ISLAND. I know of no records of reptiles from San Benito. The Academy has received specimens of but one kind of lizard, which is here described as new. =1. Uta stellata= sp. nov. PLATE VIII. _Diagnosis._--Similar to _U. stansburiana_, but with dorsal scales not imbricate, not mucronate, often separated by minute granules, a few of the dorsal rows weakly keeled; caudals weakly keeled and very shortly mucronate, not imbricate; fifth toe not reaching end of second. _Type._--Adult male, Cal. Acad. Sci. No. 4704, San Benito Island, Lower California, Mexico, R. H. Beck, May 6, 1903.
