The only important difference distinguishing this species from the 
preceding is the greater width of the band-like supraoculars, which 
cover nearly entirely the supraocular region, being separated from 
the supraorbitals by one and from the supraciliaries by one or two 
series of very small scales. The scales on the body a trifle larger 
than in 7’, torquatus.
