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 ui)|)erjaw 

 being somewhat nearer the outer tliaii tiio inner margin ; choanio 

 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.

Differs from the preceding in the much narrower alveolar sur- 

 face of the jaws, the median ridge of the upper jaAV being nearer 

 the inner than the outer margin ; choanae 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
