rivularis Taylor was also taken. The two forms are undoubtedly 
closely related, and many of the actual differences can scarcely 
be described. The differences in color are strongly marked, 
particularly the orange or red bars on the back, and the yeilow 
belly. Tropidophorus rivularis is usually mottled gray and 
brown above with indistinct darker bands, the belly red-orange, 
the throat deep black. The width of the head is greater in this 
new species as are also the width of the chin shields and the dis- 
tance between the angle of the jaws; the count of lamelle under 
the longest toe is greater. There are only four instead of five 
labials in front of the large subocular labial. Tropidophorus 
rivularis was never found save along streams and brooks; on 
the other hand, 7. stejnegeri was found on spurs of mountains 
in dry situations, never near water. 
Stejneger has described Tropidophorus misaminius from 
northern Mindanao. It is, however, more closely related to 
T. rivularis, since it has the five labials preceding the subocular 
labials. He states that the keeled scales form eight straight 
longitudinal rows in his species; in T. stejnegeri there are but 
six. 
The species is named for Dr. Leonhard Stejneger, the emi- 
nent herpetologist of the United States National Museum, Wash- 
ington, D. C.

At the time I was preparing my paper on the genus Brachy- 
meles* I did not have at hand Fischer’s original description, 
but depended on Boulenger’s Catalogue * for my identifications. 
I have since obtained a photographic copy of Fischer’s paper 
and find that the species I described as Brachymeles suluensis is 
B. gracilis (Fischer) but not B. gracilis Boulenger, an entirely 
different species, which I have named B. boulengeri. 
Brachymeles gracilis (Fischer) is characterized by the small 
head, elongate body, and the great distance between the limbs, 
which are much reduced. The similarity between the head 
scales of this and those of various other species of the genus 
is very striking.
