large to be put into my bottle, I hung it up and left it till the follow- 
ing morning, intending to skin it. When I went to look for it at 
daylight, it was nowhere to be seen. The Indians said a dog had 
probably eaten it. 
The principal places in the neighbourhood of which I collected 
during my stay in Guatemala last year and the early part of the pre- 
sent were Duetias, Coban, and Lanquin. The former village is situ- 
ated between the volcanos of Agua and Fuego, on an offshoot of the 
table lands. It is elevated about 4700 feet above the level of the 
sea. Coban, in Vera Paz, stands at an elevation of 4500 feet, on 
some broken and undulating ground, shut in on three sides by moun- 
tains. Its position is somewhat peculiar, being isolated in its tem- 
perate climate from the table lands by having on all sides a “tierra 
caliente,” its only connexion with the back bone of the Cordillera 
being a tortuous and narrow ridge of mountains. Lanquin, though 
only about thirty-five miles to the eastward of Coban, is quite in the 
hot district. It lies in a hollow surrounded by high mountains. 
Here it was that most of the Tropical species were collected. 
In collecting I received great assistance from Mr. Robert Owen of 
San Gerénimo, who secured for me many specimens at Coban while 
i was absent in the mountains, and also made several additions at 
San Gerdnimo before forwarding my last collection to England. 
The synonymy of each species I take from Dr. Gray’s and Dr. A. 
- Ginther’s Catalogues of the Reptiles in the Collection of the British 
Museum. I must add, that I have had the full benefit of Dr. Giin- 
ther’s great knowledge of this subject. Both in determining the 
species and in the remarks upon them, I have largely availed myself 
of his suggestions. 
BAsILISCUS AMERICANUS, Laur. 
This Basilisk is very common at Lanquin, where I had no diffi- 
culty in obtaining plenty of specimens of both sexes and all ages, by 
offering the Indians a small reward for all they brought. They may 
frequently be seen on the low branches of a bush, and are particu- 
larly fond of basking on the boughs ofa felled tree in a clearing near 
a stream. When running fast, they carry the tail slightly elevated. 
At Duejias this species is more rare; I saw but three or four spe- 
cimens, and only succeeded in securing one. In some specimens of 
the males, the tail is much more compressed than in others. In the 
series of young the crest is shown in all stages of development. 
CoryYTHOPHANES CRISTATA, Boie. 
Agama cristata, Merrem. 
Is not nearly so numerous as the Basilisk. I obtained but one 
specimen, which was brought to me at Lanquin. 
ANOLIS SALLI, Giinther, P. Z.S. 1859, p. 421. 
I obtained two specimens of this Anolis at Duenas.
