ANOLIS FRASERI, Giinther, P. Z.S, 1859, p. 407. 
Coban ; several specimens. All the examples of both these species 
of Anolis are immature. 
TROPIDOLEPIS TORQUATUS, Gray. 
Agama torquata, Wiegm. Herpet. Mex. p. 49. pl. 7. 
By far the commonest Lizard in the country, and very generally 
distributed. The colouring appears to vary considerably in different 
individuals, as has been stated by Wiegmann. In some the blue of 
the under parts is barely traceable, nor is the black collar round the 
neck shown. In others these are very decidedly defined, while some 
have in addition a reddish-yellow crescent-shaped mark on the lower 
part of the chin. They are found usually about walls and hedge- 
rows. 
CNEMIDOPHORUS UNDULATUS, Wiegm. Herpet. Mex. p. 27. 
This is also a common species, but not so abundant as 7’. torquatus. 
I found it at Duefias, Coban, and Lanquin. This Lizard also ex- 
hibits a great diversity of colouring on the flanks. The shields of 
the head become very irregular in some of the older examples, and 
assume a tubercular appearance. 
GERRHONOTUS WIEGMANNI, Gray, Cat. of Lizards, p. 54. 
Not at all common. A single specimen obtained at Lanquin was 
the only one that came under my notice : this I caught on the con- 
vent wall. It was shown me by the priest, who said that he had 
noticed it on the same spot several nights in succession. 
TYPHLOPS TENUIS. 
Eyes imperceptible ; tail exceedingly short, obtusely conical, 
scarcely bent downwards. Middle of the trunk surrounded by seven- 
teen series of scales. Nasal shields reaching as far backwards as the 
rostral shield; two more shields behind the nasal. The length of 
the body 64 times the diameter of the girth. Each scale on the 
back brown, with lighter margin; belly dirty whitish. 
Length 12 inches; length of the tail 1? line. 
Hab. Coban in Guatemala. 
One specimen of this apparently new Typhlops was brought to 
me at Coban by an Indian boy. 
STREPTOPHORUS SEB#, Dum. et Bibr. 
Very abundant at Coban, being found in the grass growing on 
each side of the streets. 
One specimen is variegated, black and dirty white beneath. 
HoMALOCRANION ATROCINCTUM, Dum. et Bibr. 
Calamaria atrocincta, Schleg. 
One specimen was killed at Duefas among some logs of wood.
