Eumeces 
There are in China two very distinct species of the genus 
Eumeces. The one characterized by the possession of but one 
unpaired postmental is E. elegans. The other, which normally 
has two azygous postmentals, is E. chinensis. Vhe former is 
represented in Japan, the Loo Choo Islands, the Pescadores 
and Formosa by a number of species and subspecies which 
may be spoken of as the Ewmeces elegans group. The latter, 
FE. chinensis, seems to have no representatives in Japan and 
the northern and central islands of the Loo Choo archipelago, 
but has close relatives in the southern islands and in Formosa. 
The Formosan specimens have been regarded as identical with 
the mainland examples of FE. chinensis. The specimens from 
Miyako, Ishigaki and Iriomote have been described as E. 
kishinouyet. 
The members of the E. chinensis group seem everywhere 
to be less numerous than those of the E. elegans group. We 
have received only one specimen from China, four from For- 
mosa, and seven from the southern islands. This material is 
too limited to give really satisfactory results, but it seems to 
indicate that both the Loo Choo and the Formosan lizards 
should be regarded as distinct subspecies. The chief differ- 
ences are indicated in the Key given below.
