the keels obliquely turned towards the vertebral line; laterals a

Apparently very closely related to LZ. vittatus. Scales of the back 
large, the keels unusually strong. Crest highest on the tail. 
General colour light green, principally appearing above in two 
dorsal bands and in the interspaces of a series of about ten trans-

less confluent in old males, as do also sometimes the vertical bars on 
the sides, which are often present; posteriorly beneath spotted with 
greenish white; gular region coarsely reticulated with black.
