Cope, E. D. On the Distribution of Batrachia and Reptilia in North 
America. P. Am. Ass. xxiv. pt. 2, pp. 197 — 201 (abstract). 
The primary divisions of Sclater and Huxley are redefined, and the 
mixture of South American families and genera in the North American 
fauna regarded as sufficient ground for separating it as a primary divi- 
sion from Europe- Asia ; the sub-divisions adopted are six.' The author 
finds that on the whole the North American fauna is peculiar in its 
Salamanders, “Old World” in its Frogs and most of its Turtles, and 
South American in most of its Snakes and Lizards, and some of its 
Turtles.

CouES, E. Synopsis of the Beptiles and Batrachians of Arizona ; with 
critical and field notes, and an extensive synonymy. In Wheeler's 
Bep. Geogr. Explor. W. of 100th mer., v. Zoology (Washington : 
1875, 4to), chap. v. pp. 685-633, pis. xvi.-xxiv. 
83 species (with numerous sub-species) are discussed, the term “ Ari- 
zona” now including the western half of New Mexico and a consider- 
able part of Sonora. 9 other species from Arizona are included in Dr. 
Yarrow’s synopsis {infra). The region, being dry, is poor in Batrachia^ 
but rich in Ophidia and Sauria, the species of the two latter groups (34 
and 36) preponderating in number over those of any other portion of 
the United States. \

Beptiles made in portions of Nevada, Utah, California, Colorado, 
New Mexico, and Arizona, during the years 1871, 1872, 1873 & 1874. 
In Wheeler Bep. 1. c. chap. iv. pp. 509-584, pis. xvi., xviii., xix., 
XX., xxiii.-xxv. 
87 species (17 Batrachia^ 26 Ophidia, 35 Lacertilia, and 3 Testudinata) 
are discussed, including one new genus of Ophidia and 6 new species. 
An extraordinary mimicry of colour of surrounding objects, both by 
serpents and lizards, is noted (p. 512). 
D. Jordan’s “Manual of the Vertebrates of the Northern U. S.” 
(Chicago : 1876, 8vo), contains a systematic index to the Reptilia and 
Batrachia (pp. 157-198).
