the Taiwan Museum is one said to have been collected at 
Horisha, Formosa. ; 
This species combines several of the characters of O. tem- 
pletoni and subgriseus but seems to be distinct from both. 
It resembles O. waandersu and melanocephalus in the pos- 
session of an undivided nasal plate. 
Callophis macclellandii (Reinhardt) ? 
In the Taiwan Library is a peculiar specimen of a Callophis 
which differs so much from the usual C. macclellandii that our 
collector, failing to secure a specimen like it, has sent us a 
photograph and some careful notes concerning it. The speci- 
mien in question was collected at Giran, Formosa. 
The left maxilla has been destroyed. No small teeth could 
be made out on the right maxilla. There are one pre- and 
two postoculars; seven supralabials, the third and fourth enter- 
ing the eye; frontal nearly as long as the parietal; temporals 
1-1; genials nearly equal, anterior in contact with anterior four 
infralabials; scales in thirteen rows; gastrosteges 243; uro- 
steges 29; anal divided; tail ending in a spine-like scale. 
The head is black with a white band across adjoining 
halves of the sixth and seventh labials, the temporals, anterior 
half of parietals and posterior third of frontal. There is a 
black dorsal stripe covering the median scale-row and half 
of the adjoining row on each side. External to this is a 
brown stripe covering two and one-half rows, while the outer 
three rows are occupied by a black lateral stripe. This outer 
black stripe is interrupted by twenty-one white spots, each 
followed by a black blotch which encroaches on the fourth 
scale-row and on a gastrostege. These white spots are farther” 
apart and smaller posteriorly. Gastrosteges with black spots 
and cross bars for about one-third of surface. 
There is some doubt as to whether this specimen represents 
an undescribed species or merely an individual variation from 
the usual coloration of C. macclellandii but it seems best to 
regard it as the latter, at least until a specimen is received. 
We have received C.:maccellandiu from Kosempo and Sui- 
shako, Formosa.
