PLATE VII, Figs. 3-4.
Gerrhonotus scincicauda Van Denburgh, Occas. Papers, Cal. Acad. Sci. 5, 1897, p. 106.
I am unable to distinguish six specimens (Cal. Acad. Sci. Nos. 3881-3883 and 3896-3898) collected on Santa Rosa Island from the species now known as G. scincicauda; that is to say, the form with fourteen longitudinal rows of scales, single interoccipital plate, large azygous prefrontal, longitudinal lines along the middle of each row of ventral scales, and smooth temporals. This clearly is the form to which Baird and Girard applied the name G. scincicauda, but that it is the species originally described by Skilton seems far from certain.[5]
The specimens from Santa Rosa Island all have dorsals in fourteen longitudinal series. The number of transverse series between the interoccipital plate and the backs of the thighs is fifty in one specimen, fifty-one in three, fifty-two in one, and fifty-three in one. One has the brachial scales very weakly keeled. They were collected by Dr. Gustav Eisen in June, 1897.
Santa Cruz Island.
A Hyla and two species of lizards have heretofore been recorded as inhabiting Santa Cruz Island. Another lizard is here reported for the first time.
1. Hyla regilla Baird & Girard.
Hyla regilla Yarrow, Bull. U. S. Nat. Mus. no. 24, 1882, p. 171; Cope, Bull. U. S. Nat. Mus. no. 34, 1889, p. 360.
Yarrow and Cope record this species as having been collected on Santa Cruz Island by Mr. H. W. Henshaw in June, 1875, but another portion of the same lot of specimens (U. S. Nat. Mus. No. 8686) is stated to be from Santa Cruz, California. Mr. Henshaw tells me he never has collected in Santa Cruz County, and that these specimens unquestionably came from Santa Cruz Island where he collected in the summer of 1875.
2. Uta stansburiana Baird & Girard.
