masquerading under a trinomial, but which is so dis- 

 tinctly different from C. ventralis that there could 

 have been no intergradation for maity ages past. Uta 

 thalassina Cope, another record from the Cape Re- 

 gion, is interesting because of possible differences of 

 opinion regarding its generic rank (Petrosaurus, new 

 genus suggested by Boulenger, 1885). The discov- 

 ery in 1914 of Uta mearnsi Stejneger, from the sum- 

 mit of the Coast Range of the Mexican border, really 

 settled the question, as stated by Stejneger at that 

 time (Proc. U. S. Nat. Mus., 1894, p. 369). When 

 we compare this species with the large Cape Region 

 form on the one hand, and with the small typical Uta 

 on the other, we find it a close link in size, in scutel- 

 lation (except for the tail), and even in color pat- 

 tern. Therefore, Uta thalassina must be retained 

 among the Utas despite the fact that the scutellation 

 of its tail is unlike that of any other Uta known, and 

 more like that of a Crotaphytus.

ANOTHER LONG ISLAND RECORD FOR 



AMBYSTOMA JEFFERSONIANUM 



(GREEN). 



Three specimens of this salamander were found 

 on August 26, 1917, under old boards along the mar- 

 gin of a small, round pond about Va mile north of the 

 Hither Plain Life Saving Station at Montauk. All 

 are young, two measuring 224 " and one 3^" in length. 

 Undoubtedly they have developed from larvae of the 

 same season. The largest specimen is heavily marked 

 with bright blue spots of varying size on tail, legs 

 and along the sides of body and head. On the back 

 and underside the spots are more faint and sparse. 

 The ground color is blackish brown. The tail is oval, 

 flattened toward the point. On the smaller specimens 

 the spots are faint and the tail is flatter throughout 

 its length.
