1. KACHUGA, 55 
large, axillary smaller. Head moderate; snout obtuse, moderately 
prominent ; jaws with denticulated edge, upper not notched mesially ; 
alveolar surfaces very broad, the median ridge of the upper Jaw 
being somewhat nearer the outer than the inner margin; choanze 
behind the line of the posterior borders of the orbits; the width 
of the lower jaw at the symphysis equals the diameter of the orbit. 
Limbs with transversely enlarged, band-like scales. Brown above, 
yellowish inferiorly ; nape with red longitudinal lines. 
Length of shell 37 centim.

Differs from the preceding in the much narrower alveolar sur- 
face of the jaws, the median ridge of the upper jaw being nearer 
the inner than the outer margin; choane between the orbits ; 
the width of the lower jaw at the symphysis is less than the dia- 
meter of the orbit. Considerable uncertainty prevails in the dis- 
tinction of isolated shells of this species from the preceding. The 
male B. trivittata is characterized by three black longitudinal bands 
on the carapace, which are absent in the female according to 
Theobald, whose opinion I am disposed to endorse rather than that of
