on the edges of the ventrals; the yellow spots in the black cross- 
bands are strongly pronounced, continuing some distance on the 
tail, less distinct on the neck. No spots on the parietals and 
no nuchal spot; black marks on lower labials at the sutures; 
spots on the first three upper labials and on the sixth. 
Scalation.—Nine upper labials, ten lower labials; one pre- 
ocular on left, two on right; three postoculars; temporals two, 
followed by three, the lower anterior very large; scales in 
seventeen rows; tip of tail missing; anal, double; ventrals, 168. 
This is the first record of the snake from Basilan. 
This species differs from Natrix barbouwri sp. nov. in the 
larger eye and the dentition.

I collected three specimens of this snake in 1920; two near 
Zamboanga, and one on Basilan Island. Gregorio Lopez col- 
lected a specimen at Cabalian, Leyte. The specimens from Zam- 
boanga and Basilan have rather shorter, wider heads than the 
Leyte specimen has, and a higher average of ventrals, the counts 
for the two Zamboanga specimens being much higher than any 
recorded counts. The known range is: Ventrals, 162 to 189; 
subcaudals, 49 to 66. The chin shields of the Leyte specimen 
are longer and narrower than those of the other specimens. 
The Zamboanga specimens were found in a rotted tree stump. 
The Basilan specimen collected at Abung-abung was found at the 
base of a small palm tree.
