216 DR. H. GADOW ON MEXICAN [June 6, 
Yucatan to the State of Vera Cruz, absolutely confined to the 
Atlantic Tierra Caliente, in forest-land ; arboreal, or rather amongst 
shrub-like trees, the brown bark of which this curious-looking ~ 
gentle lizard looks to for protection. It feeds upon insects. 
Lemanctus.—The two Mexican species are excessively rare, 
perhaps because they live higher up in the trees, where it is then 
next to impossible to discover them. J. serratus is known from 
Campeche and the States of Vera Cruz and Oaxaca without localities. 
L. longipes, hitherto known from Jalapa only; all the more re- 
markable is the solitary specimen which I found amongst a 
collection sent to.the Field Columbian Museum from the State of 
Colima. 
Anolis, with at least a dozen species in the Hastern or Western 
Tierra Caliente. A. nebulosus has the widest range in Mexico, 
from Tehuantepec to Jalapa, and to Ventanas on the west; I 
found it not only on the coast of Guerrero, but also on the 
Nevado de Colima, up to at least 7600 feet, together with A. lio- 
gaster. A. gadovuw at Tierra Colorada, in bush-land. The Anolis 
seem to spend most of their time on the lower branches of shrubs 
and trees or amongst the rank herbaceous vegetation, waiting for 
insects, and trusting to not being seen when basking. Especially 
when they have become excited by being pursued, the males 
stretch out their mostly beautifully-coloured gular sac. None 
of the Mexican species which I have observed displays any marked 
change of colour like the A. carolinensis, the “‘ Chameleon” of the 
Americans. 
TEs1IDz* are clearly a Neotropical family, with several dozen 
genera in South America. Of all these, only Ameiva and the 
closely-allied Cnemidophorus extend through and beyond Central 
America: Amewa into the Eastern and Western hot-lands of 
Mexico and into the Antilles; Cnemidophorus through Mexico 
into the United States, where C. sealineatus has spread over nearly 
the whole Union. This genus is entirely terrestrial, preferring 
sandy districts with bush-land; only C. guttatus is a typical 
inhabitant of the lowland forests of Vera Cruz. The Mexican 
species avoid the high plateau, 5000 feet being about the upper 
limit. The only exception is made by C. guluris, which has 
been credibly recorded from Guanajuato, and of which I have 
examined specimens collected by Dr. Meek close to the town of 
Puebla, which lies at an altitude of more than 7600 feet, higher 
than the Valley of Mexico, where Cnemidophorus does not occur. 
Concerning distribution and variation, ef. my paper, “ Evolution 
of the Colour-pattern and Orthogenetic Variation in certain 
Mexican Species of Lizards, with adaptation to their surroundings,” 
Proc. Roy. Soe. vol. lxxii. p. 109 (1903). 
Ameiva wndulata, the only species in Mexico, is an inhabitant 
* From the Aztec “teco-ixin,” ¢. e. Rock-lizard, the name of Sceloporus torquatus, 
misspelt and misapplied. The Zapotecs and Mazatecs call Cnemidophorus and 
Ameiva Zumbichi and Cachumbo.
