tail, with crescentic marks upon the nape, as in Varanus piloticug, and 
light and dark variegations upon the front and chin, (Smiths. No. 5742^.) 
Specimens (adults, No. 5738) in Mil's. Smithsonian, from Monte Verde, Cuba, 
Mr. 0. Wright discoverer ; also Mus. Acad. Nat. Sciences. This interesting 
species resembles somewhat the form of A. (?) carolinen si 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 in is o lep is, 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. Gunther, viz., that but one egg at a time is impregnated 
and excluded.

The genus first defined by Mr. Gossa, as above, though previously named by 
Fftzinger, 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 Sc.incidae, 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 iodurus, and opalinus most closely. It 
is interesting to observe that both these species, and Euptistis Edwards i i, 
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, in order to 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, prevented 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 lornvia 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 leucophrys , and Anthus 
hdovicianus were very abundant ; and Pinicola Canadensis and Turdus Alicice 
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.]
