Coloration in life of adult female, Cat. No. 4950 Stan. Univ. Mus. 

 Above golden brown, darker on top of head and along base of dorsal 

 crest; limbs above like back. Sides of head brownish; sides of 

 throat and body bright brick red ; a slaty antehumeral spot with black 

 center. Belly and inferior surfaces of limbs cream ; tail yellowish 

 below. Chin greenish; rest of lower jaw, throat and breast buffy. 

 Eyelids dark blue-green. 



The collection contains eleven adult females, all of which exhibit 

 considerable variation. Mandible and throat in some spotted with 

 dusky ; tail dorsally black-barred and dorsum bronze-brown in a few 

 specimens. 



Length of head and body 57 to 6 1 mm. 



This is the smallest and in some respects the best marked species in 

 the archipelago. 



Occurs abundantly near the coast at Wreck Bay. None were seen 

 inland more than a mile from the coast, their absence being due prob- 

 ably to the saturated condition of the soil and great amount of surface 

 water. 



Food consists of insects, spiders, blossoms and seed capsules, the 

 former predominating in the stomachs examined.
