 on the sides. The immature males are unspotted above like the 

 females.

Coloration in life of adult female. Cat. No. 3874, Stan. Univ. Mus., 

 from Hood Island. Body and tail above olive-brown; limbs similar 

 in coloration. Sides of belly and tail reddish ; a black antehumeral 

 spot. Whole head, throat and chest brick red, becoming darker on 

 nape and top of head, fading to dull orange on anterior belly; belly 

 and tail and hind limbs inferiorly cream-yellow; fore limbs below

There are nineteen adult females in the collection from Hood and 

 Gardner Islands. A single specimen has the breast dark-spotted, all 

 the others being immaculate below.

This is the largest species of the archipelago. Some specimens from 

 Narboro nearly equal it in size but differ much in coloration and size 

 of scales. Some forms of T. grayi approach it somewhat in colora- 

 tion but the red on the sides of tail and the unspotted lower parts of 

 the female seem to be distinctive.
