 tubercle on theintestinal region; frontal margin concave. Pterygostoinian 

 regions with a longitudinal, tuberculated prominence. Antero-lateral 

 angles of the buccal area with three prominent lobes which project in 

 front of the maxillipeds. Sternum and abdomen tnberculated. Maxilli- 

 peds with prominent tubercles. Merus of the chelipeds cylindrical, tuber- 

 culated like the carapace; carpus and hand granulated. Ambulatory legs

 off San Diego, 30 fathoms! 



Easily distinguished from ornata by the numerous 

 bead-like tubercles on the carapace and the lobes at the 

 anterior end of the buccal area. 



Tribe MACROURA. 



Body generally elongated, though sometimes broad. Abdomen gener- 

 ally large and exceeding the carapace in length, the sixth segment usually 

 bearing well developed pleopods which, with the telson, form a strong 

 tail-fin. Eye-peduncles not lodged in well defined orbits. Antennules 

 generally elongated and not lodged in fossettes. Antennae usually furnished 

 with a scale (exopod) attached to the second joint. The external maxilli- 

 peds are typically pediform. Any or none of the pereopods may be chelate.
