the most characteristic differences are in the colour mark- 
ings. Whereas the first is of a simple brown colour 
ornamented with large lighter ocelli, and with but faint 
indications of cross-bands, O. ornatus is closely marbled 
with dark brown ona lighter ground, the marbling forming 
cross-bars at intervals and enclosing imperfect ocelli only. 
The supralabial lobes of O. ornatus are generally fewer in 
number and more robust than those of O. maculatus, being 
from 2 to 4 as against 3 to 6, and the posterior lobes are 
generally simple in the young of the first named species. 
These, however, are very variable, and it may prove 
that the one species is only a well marked colour variation 
of the other. Our sixteen specimens, however, are readily 
divisible into the two species. The specimen recorded from 
Port Moresby, New Guinea, by Macleay,* under the name 
Crossorhinus barbatus, is not this species, but O. ornatus.
