scales under fourth toe twenty-two and twenty-three: frontal 
touching frontonasal; two large preanals; one postmental; 
patch of enlarged scales on back of thigh, as in Ewmeces ele- 
gans. 
Remarks.—Although this is a perfectly distinct: species, 
readily distinguished by the enlarged scales on the back of 
the thigh, the longer snout, the coloration, and the larger 
number of scale rows, its general appearance is so like that of 
S. indicus that it was at first confused with that form. I 
believe that the specimen described by Dr. Stejneger in his 
Herpetology of Japan, p. 216, really is this species, although 
Barbour’s two specimens are undoubtedly S. imdicus formo- 
sensis. Although the proportions of the first and second supra- 
oculars, and the relation of these plates to the frontal, and the 
patch of enlarged scales on the back of the thigh, indicate 
relationship with S. jagorii of the Philippine Islands, the 
present species differs from that species in many respects. 
Thus, in S. jagorii the snout is shorter, the parietals are much 
larger, the scales around the body usually are thirty-six, the 
frontonasal is convex instead of nearly flat, and the coloration 
is quite different. 
The occurrence in Formosa of two similar species of Sphen- 
omorphus is quite as unexpected and remarkable as the pres- 
ence there of Takydromus formosanus and T. stejnegert. 
Distribution.—We have received five specimens from Ko- 
sempo, and seven from Koshun, Formosa, where they were 
secured in March, 1909; also two from Botel Tobago. The 
specimen, in: the British Museum, described by Stejneger, was 
collected by La Touche at Bangkimtsing, Formosa.

Emoia atrocostata (Lesson) 
This genus has not been recorded from either Formosa 
or the Loo Choo Islands. We now have five specimens (Nos. 
21714-21718) from Miyakoshima and ten from Formosa. 
These agree so well with Boulenger’s description of £. atro- 
costata that they must be regarded as representing this species, 
at least until direct comparison shows them’to be distinct. 
Specimens from near the type locality not being at hand, such 
comparison cannot now be made.
