Out of eleven specimens of img collected on the Trag- 
bal pass by Dr. G. Giles four belong to Alcock’s variety trag- 
bulense, while the rem eine represent the typical L. himalayanum. 
Some of the latter are very much smaller than those of tragbulense, 
which, as well as the types, are fairly wellgrown. The coloration, 
therefore, cannot be due to youth ; and though variety in colora- 
ee if combined with differences in scaling. The greater 
mber of subdigital ad on Moe ourth toe which Alcock 
eee in his specimens, is constant, re also the characteristic 
dorsal and lateral stripes, wins the atid scales have not the 
obscure dark edging common in JL. himalayanum but are 0 
an opaque white. There may be two scales under the eye; but 
this character is not constant. 
Lyaosoma BEDDOMI, Blgr. 
The only specimen in our collection which can be ass igned 
to this species differs from the descriptions in that the limbs do 
not meet when adpressed. Otherwise it conforms to Boulenger’s 
diagnosis .
