BARBOUR. AND NOBLE: LIZARDS OF THE GENUS AMEIVA. ATI 
The specimen described is one of the types received in exchange 
from the Philadelphia Academy. Ruthven (Occ. papers, Mus. zodl. 
University Mich., December 27, 1913, no. 2), has discussed the 
locality data of the types and concludes, “It is highly probable that 
Amewa bifrontata does not occur on St. Thomas but is a Venezuelan 
form that is represented in Colombia by Ameiva divisa (Fischer).”’ 
We may emphasize what Ruthven has said viz., that this lizard cer- 
tainly does not occur upon St. Thomas, this is proved by the recent 
carefully made collections. There is no reason to believe that it ever 
did. It is found in Venezuela, and is probably confined to that state. 
Habitat:— Venezuela. 
AMEIVA BIFRONTATA DIVISA (Fischer). 
- Deseription:— Adult male; M. C. Z. 10573; near La Tigrera, Santa 
Marta Mts., Colombia; 1913; A.°G. Ruthven. 
This race differs from typical bifrontata only slightly in scutation 
but decidedly in coloration. As Ruthven (Occ. papers, Mus. zodl. 
University Mich., December 27, 1913, no. 2), has pointed out the 
Colombian race differs from the Venezuelan form in having the series 
of granules on the inner margin of the supraoculars ending on the 
posterior corner of the second instead of having the “three posterior 
supraoculars surrounded with granular scales.’’ This seems to be 
the only real difference in their scutation. 
Coloration: — Dorsal surface olive-gray tinged with bluish; on each 
side a broad stripe of dark olive-gray bordered above and below by 
narrow, pale bluish lines; several dark olive-gray spots on the back; 
head, thighs, and tail tinged with brown dorsally; the head varying 
to a fleshy color on the sides; dorsal surface of thighs and tail faintly 
reticulated with black, and spotted with pale olive-gray; ventral 
surface milky varying to pale blue on the sides; the outer ventrals 
spotted with pale turquoise-blue. 
Remarks:— The description was made of an adult male that meas- 
ured one hundred and twenty-eight millimeters from snout to vent. 
Habitat:— Three adult males from the Santa Marta Mts. were 
examined, but this race is probable widely spread over the north of 
Colombia. 
AMEIVA RUTHVENI, sp. nov. 
Description:— Adult male; Tyre M. C. Z. 9931. Panama (near 
city); 1904; W. W. Brown, Jr.
