lamellae, and the latero-dorsal row of scales assumes the form of a fringe, more developed 
in the latter than in the former. In Crossobamon there is practically the same 
structure of digit as in S. petrii, but the fringe becomes so greatly developed as to 
recall the fringe of an Acanthodactylus. It is thus evident that the digits of these 
supposed genera do not differ very materially from one another. 
In Bunopus the nostril is defined by the rostral, first labial, and three nasals, and 
the development of these scales is much the same as in Stenodactylus ; whereas in 
Alsophylax the first labial is very large and defines not only the lower, but the posterior 
border of the nostril as well, thus differing materially from the very limited relation 
of that shield to the nostril in Bunopus. In Alsophylax also there is a well-developed 
upper nasal shield, quite unlike the scaly nasals of the latter genus. Also the tail of 
Alsophylax instead of being in verticils defined by enlarged tubercles is non-verticillate 
and covered with smooth imbricate scales.
