elongate nuchal. The length of the leg is contained in the axilla- 
to-groin distance four and six-tenths times. Scales in twenty- 
four rows around body. 
No. 1520, collected at Abung-abung, differs from the type in 
having the parietal broken into two scales, as have certain speci- 
mens of Brachymeles vermis Taylor and Sphenomorphus bipa- 
rietalis Taylor, both from the Sulu region. The first pair of 
chin shields is separated by a small single shield. Scales in 
twenty-four rows around body. 
This species probably does not attain as large a size as the 
other pentadactyl species of the genus. It is a burrowing form 
and is usually found under logs or stones. The lizards of this 
species move with great rapidity. It is difficult to grasp them 
because of their extremely smooth scales.

Twenty-one specimens of this species were taken at Zambo- 
anga, Basilan, and Jolo. They agree very well in color and 
markings. A single specimen was collected in southern Leyte, 
by Gregorio Lopez. 
The head scales are variable. Thus, of the twenty-two speci- 
mens, twenty-one have the supranasals in contact and one has 
them separated. In seventeen specimens the parietals form no 
suture; in five specimens they do. Seven specimens have the 
fourth labial entering the orbit; fifteen, the fourth and fifth. 
The character of the chin shields is apparently invariable, save 
in one Jolo specimen, which has the second pair wider than the 
first pair.

Eight specimens of this small wormlike form were collected 
on the Government cattle ranch near the central part of Jolo 
Island. They were found under leaves and trash along a small 
stream. 
All the specimens agree in the arrangement of the chin 
shields; that is, having the first pair separated and the second 
pair wider than the first pair, separated by a single scale. All 
have the postmental in contact with a single labial. 
In the conformation of the head scales they agree in general
