Ophisaurus harti Boulenger? 
The presence in Formosa of a species of Ophisaurus 
is attested by a specimen now in the Taiwan Medical School. 
This specimen was collected, by the late Rev. Mr. MacKay, at 
Tamsue. Another specimen, collected at Shinchiku, was for- 
merly in this museum, but has been lost. We have not as yet 
secured a specimen, but our collector states that individuals 
-have been seen at Takao sunning themselves on a stone wall 
that borders a grove of screw pines. 
The general relationship of the fauna would lead one to 
suspect that the Ophisaurus of Formosa is probably identical 
with Boulenger’s O. harti from Fokien, China; but the notes 
which I have received concerning the specimen in the Medical 
School indicate that the Formosan lizard is distinct. The 
matter must remain undecided until a specimen is received for 
examination.
