collecting on the western and central portions of the island but without 

 finding any traces of Tropidurus. 



Indefatigable Island. An adult male, Cat. No. 4862 Stan. Univ. 

 Mus., from Indefatigable shows the following coloration. Above 

 olive-brown, head lighter brown; back marked anteriorly with trans- 

 verse blackish bars ; whole dorsal surface except the head spotted with

 reddish, finely black-spotted. Breast and lower jaw rosy red, with 

 large black blotches; throat black. Belly light greenish-gray; tail 

 and hind limbs inferiorly light blue-gray. Fore limbs spotted below 

 like breast. 



Thirty-seven adult males are in the collection, nine from the north- 

 ern coast of Indefatigable, twenty from South Seymour and eight from 

 North Seymour Island. The coloration of the breast varies from red 

 through orange to buff, the black blotches in some specimens obscur- 

 ing the ground color; in some others the breast is only sparingly 

 spotted. A few are light errayish above, like T. g. barringtonensis. 



Length of head and body 72 to 80 mm. 



An adult female, Cat. No. 4875 Stan. Univ. Mus., from Indefati- 

 gable, is olive-brown above, becoming lighter qn head and tail. Sides 

 of head and neck from snout to antehumeral fold brick-red. A black 

 ante-humeral spot. Sides of body reddish, unspotted. Mandible 

 and breast posteriorly yellowish ; the chin reddish. Throat light slate, 

 darker spotted ; forebreast lighter grayish, dark-spotted. Belly, hind 

 limbs and tail inferiorly grayish. 



Twenty-seven adult females are in the collection from Indefatigable 

 and the Seymour Islands. These show little variation in coloration. 

 Several are marked on the sides by two dark longitudinal bands, the 

 lower band extending from axilla to thigh, the upper from ear to 

 above thigh. 



Length of head and body 58 to 67 mm. 



In the Indefatigable specimens the male approaches much nearer 

 the size of the female. The females are scarcly distinguishable in 

 coloration from some specimens from James Island, while the males 

 approach closer in size and coloration to Albemarle specimens. 



Generally distributed, most abundant coastwise. The specimens 

 from the Seymour Islands show scarcely any variation from those 

 taken on Indefatigable. They average slightly lighter colored and 

 larger.
