"=Tropidolepis scincicauda=, n. s. Slender, tail much longer than body, cylindrical. Dermal plates of the body and tail, carinate above, smooth beneath, verticillate. The carinate plates in nine rows. Color, dusky green above, light ash color below. A row of small dark spots on each flank. Another row of smaller ones along the vertebral line. Some of the dark colored scales on the flanks tipped with a whitish color. Length five to five and a half inches." The plate accompanying Skilton's article is so poor as to throw no light on this question, and it seems best to make no change in the nomenclature until some one has examined Skilton's specimens, one of which, according to Yarrow's Catalogue, is No. 3089 of the National Museum collection.] 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_. _Uta stansburiana_ YARROW, Bull. U. S. Nat. Mus. no. 24, 1882, p. 56; TOWNSEND, Proc. U. S. Nat. Mus. v. 13, 1890, p. 144; VAN DENBURGH, Occas. Papers, Cal. Acad. Sci. 5, 1897, p. 68; COPE, Report, U. S. Nat. Mus. 1898 (1900), p. 310. The register of the United States National Museum states that two specimens of this lizard (No. 8619) were collected by Dr. O. Loew, on Santa Cruz Island in June, 1875. These lizards are still in the National collection and are of considerable interest since they, and two from Ana Capa Island, are the only ones I have seen which approach the San Benito Island _Uta_ (described below) in the character of their dorsal lepidosis. That these specimens actually were collected by Dr. Loew on Santa Cruz Island is, I think, open to little doubt, since he, with Mr. H. W. Henshaw and Dr. J. T. Rothrock, visited this island in June, 1875.[6] [Footnote 6: See Report, Chief of Engineers, U. S. A. 1876, pt. 3, pp. 435, 445, etc.]
