xiir, D, 5 Taylor': Reptiles of Sulu Archipelago 251 



tance ; thirty-two scale rows around body, those on belly largest, 

 lateral rows in straight longitudinal lines; preanal scales not 

 enlarged ; third and fourth toes almost of equal length, ten smooth 

 lamellae under each ; scales on underside of tail not enlarged ; ear 

 much nearer the foreleg than end of snout. 



Color in life. — Above brownish, many of the scales flecked 

 with whitish; a more or less distinct light-dotted line from 

 behind eye along side; below this a stripe of slightly darker 

 brown flecked with white; belly cream, underside of tail flecked 

 with brown ; upper and lower labials with light spots.

Variations. — Eleven other specimens are at hand for com- 

 parison. They are from various localities in the Archipelago, 

 distributed as follows: Basilan, 1; Jolo, 4; Lapac, 2; Tawitawi, 

 1; Sangasanga, 1; Papahag, 2; Bongao, 1. The Basilan speci- 

 men is darker and is more heavily built; the head slightly 

 broader, and scales in thirty-six rows about body ; the prefrontals 

 are broadly in contact; throat with black spots; two frenals 

 present on right side. Specimens from Jolo are lighter, the 

 two lateral light lines being more or less distinct. The type 

 is from Lapac. Specimens from the more southern part of 

 the Archipelago vary from thirty to thirty-four scale rows about 

 the body. The labials vary between five and six. 



Remarks. — This species seems to be very clearly differen- 

 tiated by the arrangement of the parietals, which is different 

 from that of any other species in the Islands. The only lizard 

 in which this condition is approached is Brachymeles vermis 

 Taylor, found on Papahag, near Tawitawi.
