Remarks.—In a previous publication “ I stated in a footnote: 
“T strongly suspect that N. crebripunctata Wiegmann is indeed 
N. spilogaster. I believe further that Boulenger’s species of 
this name is a distinct species.” After obtaining a copy of 
Wiegmann’s type description, and comparing it with young and 
half-grown specimens of Natriz spilogaster (Boie) from Manila, 
and after obtaining specimens of a Natrix which is undoubtedly 
Boulenger’s Tropidonotus crebripunctatus and comparing these 
with Wiegmann’s type description, I have no hesitancy in placing 
Tropidonotus crebripunctatus of Wiegmann as a synonym of Na- 
trix spilogaster (Boie) and making a new species of the Natrix 
I have found, and which appears to be the same as that which 
Boulenger calls T. crebripunctatus. 
Variation.—There are only two specimens in my collection 
and a very young one in the collection of the College of Agri- 
culture at Los Bajios that I believe belong to this species. 
The cotype is likewise from Balbalan, Kalinga. It differs 
somewhat in scale counts from the type, as follows: Ventrals, 
163; subcaudals (tip of tail missing), 95; preoculars, 3; post- 
oculars, 2 on right, 3 on left side. In other respects the speci- 
men agrees with the type in scalation. 
The scale counts for the College of Agriculture specimen are: 
Ventrals, 160; subcaudals, 100; preoculars, 2; postoculars, 3; 
temporals, 2+2 and 243. It likewise agrees with the type 
save that the head is proportionately larger, as is natural in. 
very young specimens. 
In color the cotype differs from the type in having a very 
narrow yellow line on the median dorsal surface, broken by 
narrow black spots less than half the length of the intervening 
yellow. This continues some distance on the anterior part of 
the body. The entire latter half of the belly is gray, as well as 
“Snakes of the Philippine Islands (1922) 92.
