NATURAL SCIENCES OF PHILADELPHIA. 215 tail, with crescentic marks upon the nape, as in Varanus n i 1 o t i c u s, and light and dark variegations upon the front and chin, (Smiths. No. 5742^.) Specimens (adults, No. 5738) in Mus. Smithsonian, from Monte Verde, Cuba, Mr. C. Wright discoverer; also Mus. Acad. Nat. Sciences. This interesting-species resembles somewhat the form of A. (?) c a r o 1 i n e n s i s, from Cuba. In specimens of that species of very small size the facial rugae are promi-nent, the frontal scales much more numerous, and those of the back and belly keeled. The breadth between the orbits greater inisolepis, and the au-ricular aperture smaller. In the oviduct of the female was found a single large egg. Observations upon numerous species of Anolis, incline me to adopt the suggestion of Dr. Giinther, viz., that but one egg at a time is impregnated and excluded. Xiphocercus Valencienii Fitz., Syst. Rept. 1843. Anolis Valenciennii Dum. Bibr., Erp. Gen. iv. 131, 1837. Plncopsis ocellata Gosse, Ann. Mag. N. H. 185D, p. 346. Anolis leucocephalus Hall., Proc. A. N. Sci. Phil. 1856, p. 228. The genus first defined by Mr. Gosse, as above, though previously named by Fitzinger, is to be separated, in our opinion, not so much on account of the size of the plates of the front, but by reason of their curious homology with those of the plate headed Lacertidse and Scincidae, which is readily traced. In the tail, and nature of the dermal covering, it resembles Eupristis ; in the form of the head it imitates Anolis i o d u r u s, and o p a 1 i n u s most closely. It is interesting to observe that both these species, and Eupristis Edwardsii, Cope, inhabit with it the island of Jamaica. Notes on the Ornithology of Labrador. BY ELLIOTT COUES. During the summer of 1860 I accompanied an expedition in charge of J. W. Dodge, Esq., which visited the coast of Labrador, inorderto procure for the Smith-sonian Institution specimens of the birds to be found there, together with their nests and eggs, and to study their habits during the breeding season. The late period of arrival upon the coast, which was not until the first week in July, { revented any very extensive operations in the department of Oology, while the nature of the localities visited, joined with some circumstances of a private character, rendered the formation of a large collection of birds imprac-ticable. In the following pages, however, are embodied the results of my in-vestigations ; and though the list of the species noticed is, from my limited opportunities for observation, necessarily incomplete, it is hoped that it will not be found entirely wanting in points of interest with regard to the habits of the birds which pass the breeding season in Labrador. A brief notice of the different localities which were visited may not be con-sidered unnecessary. The first point reached was Sloop Harbor, a few miles south of Little Mecattina, where were collected most of the eggs procured dur-ing the voyage. Here the Somateria mollissima and the Utamania torda were the most abundant and characteristic birds, while the Larus argentatus, Uria grylle, and Mergus serrator were also very numerous, all breeding on the islands in the vicinity. On the 6th of July, the vessel left Sloop Harbor, and, pass-ing the Murre Rocks, where the Uria lomvia was breeding in immense num-bers, proceeded directly to Esquimaux Bay, where the greater part of the summer was spent. Here were collected most of the land birds procured, among them the new Aegiothus fuscescens. Zonotrichia leucophri/s, and Anthus ludovicianus were very abundant ; and Pinicola Canadensis and Turdus Alicia-not rare. Grouse and Ptarmigan were also met with ; and I was fortunately enabled to examine an extensive breeding place of the Mormon arcticus (?). A few days were spent at Rigolet, a station of the Hudson Bay Company, in 1861.]
