BULLETIN OF THE 



first pair. B. hartleiti Smith, from the Atlantic side of the continent, 

 resembles B. tanneri in many respects, but is distinguishable at a glance by 

 the long spine on the dorsum of the fifth abdominal segment. B. moratus 

 Smith, another allied species, differs in haying a distinct hepatic spine, a much 

 broader merus joint to the second maxilliped, in the presence of small exopods 

 at the bases of all the thoracic appendages, etc. 



Color in life, deep red, with a large patch of bright blue on the back of the 

 second, thii-d, and fourth abdominal segments ; eyes black.
