In this species the carina on the fifth and sixth abdominal segments 

 terminates posteriorly in a small acute tooth, whereas in the preceding 

 species, B, allusy these segments are destitute of teeth, the posterior margin

 convex infero-lateral borders, the third, fourth, and fifth abdominal segments 

 toothed, the sixth toothless, and in the lack of the tooth or tubercle on the 

 sternum between the first pair of abdominal appendages. B. hartlcUi Smith,
