is not very different, but the terminal fang is a trifle shorter, the distance 
from its tip to that of the first tooth being considerably less than the distance 
between the first and fourth teeth. 
The male from Douglas is markedly different from the above, the terminal 
fang of the upper jaw being longer and more slender: the distance between 
the tip of the fang and the apex of the first tooth is equal to, or very slightly 
greater than, the distance between the apices of the first and fourth teeth. This 
variety may be termed var. dolichognathus (Text fig. io b). 
The distal dorsal bristle in all these specimens reaches to a point about 
midway between the first tooth and the tip of the fang, or a trifle nearer to the 
first tooth: its surface is minutely prickled almost up to the pointed apex, 
which tapers gradually. On the outer side of the upper jaw there is an oblique 
row of simple bristles, the bases of which are in a line more or less parallel 
with the dental series. These bristles vary much in length and size, some 
being quite short, others long : the most distal one, arising from a point opposite 
to the base of the lamina, is markedly stouter than the rest, and its surface is 
minutely prickled. In the allied species B. filicornis mihi, this row of bristles

is much more uniform, the distal one being scarcely stouter than the second, 
and the first three have prickled surfaces. In both species, the slender apex 
of the flagellum is upcurled.

The locality of the type is simply “ Deutsch-Siidwestafrika.” It seems to 
be very distinct from any other species known from S. Africa.
