In describing this species Cope failed to state where his specimens were collected. Rivers later assigned them to San Nicolas Island, but the matter has remained open to question. I am, therefore, very glad to be able to record the fact that Mr. Joseph Grinnell has sent me three specimens of this _Xantusia_ taken by himself on San Nicolas Island, May 22-23, 1897. One of these specimens is uniform drab, with a few dark spots. The others are of the handsome striped style of coloration (see plate). SANTA BARBARA ISLAND. I believe no reptiles or amphibians have been recorded from this island. I have seen only the following species: =1. Xantusia riversiana= _Cope_. Mr. Joseph Grinnell has sent me four Xantusias from Santa Barbara Island. They are smaller than the specimens I have seen from the other islands, but seem to differ in no other respect. The largest is 64 mm. from snout to vent. All are dark drab above with small, discrete black spots. One shows traces of longitudinal dorsal bands near the tail. SANTA CATALINA ISLAND. One salamander, two lizards, and a rattlesnake have been taken on Santa Catalina. =1. Batrachoseps attenuatus= (_Eschscholtz_). A single specimen collected at Avalon, Santa Catalina Island, by Mr. A. M. Drake (Cal. Acad. Sci. No. 3726) seems indistinguishable from the mainland species. It has nineteen costal grooves, slender limbs, and narrow head. The coloration is uniform slaty brown above, paler below. Three specimens secured on this island by Mr. Fuchs differ from this one only in the slightly paler coloration. =2. Uta stansburiana= _Baird & Girard_. _Uta stansburiana_ COPE, Report, U. S. Nat. Mus. 1898 (1900), p. 311. This lizard has been recorded from Santa Catalina by Professor Cope. Two specimens collected at Avalon by Mr. J. I. Carlson are in the collection of the Academy (Nos. 4754 and 4755). They seem to be fairly typical _U. stansburiana_ with moderately imbricate dorsals. The femoral pores are thirteen or fourteen. =3. Xantusia riversiana= _Cope_. _Xantusia riversiana_ RIVERS, Am. Nat. v. 23, 1889, p. 1100; VAN DENBURGH, Proc. Cal. Acad. Sci. 2d ser. v. 5, 1895, p. 534; VAN DENBURGH, Occas. Papers, Cal. Acad. Sci. 5, 1897, p. 132. I have seen no specimens of this lizard from Santa Catalina, but Mr. J. J. Rivers states that he has received several from this island. =4. Crotalus oregonus= _Holbrook_. _Crotalus lucifer_ YARROW, Bull. U. S. Nat. Mus. no. 24, 1882, p. 76; STEJNEGER, Report, U. S. Nat. Mus. 1893 (1895), p. 447. Yarrow records a rattlesnake as having been taken by Mr. P. Schumacher on Santa Catalina Island in 1876. Stejneger also refers to its presence there. I have seen no snakes from any of the Californian islands. SAN CLEMENTE ISLAND. Two species of lizards are known from this island.
