98 BARBOUR — SOME NEW REPTILES 
instead of six scales; in having a greater number of transverse series of 
ventral plates, 24 as against 18; and in having a different coloration. 
In the several specimens the number of ventral transverse series varies. 
from 24 to 28. The keels of the dorsal scales are also apparently less well 
developed on the average than in the one figured by Boulenger. The color 
is characterized by the absence in all the specimens of ‘the small dark 
brown spotson the back’’ and by the presence of a well-marked dark verte- 
bral streak. Above and below the broad dark lateral bands, which are 
present as in Boulenger’s species, there are white bounding lines extending 
practically from head to tail. 
It gives me pleasure to name this species for Dr. Allen in recog- 
nition of his skilful collecting in many parts of the world.
