situated post-laterally. First pair of anteniu\? extend to the posterior 

 margin of the first thoracic segment; first joint of peduncle, oblong; 

 second joint, short. Second pair of antenna? extend to the posterior 

 margin of the third thoracic segment. 



The first thoracic segment is longer than any of the following seg- 

 ments. The epinicra are twice as })road as long. 



The first abdominal segment is short and bears indications of three 



coalesced segments. There are three 

 transverse elevations on this segment 

 which are densel}' covered with granules. 

 The terminal segment bears three trans- 

 verse elevations at the base, the median 

 one terminating in a spine. On, its pos- 

 terior margin is a quadrangular excava- 

 tion, with a long median tooth, bearing a 

 spine at its extremity. At the base of 

 the tooth is a small elevation. On either 

 side of the terminal excavation, a short 

 distance up the lateral margin, is a small 

 spine. The fixed inner branch of the uropoda is small and short; the 

 outer branch is lono-, blunt at the extremity, somewhat incurved, and 

 reaches, when open, much beyond the terminal segment. The margins 

 of the terminal segment, and the edges of the outer branch of the 

 uropoda, are pubescent. 



The legs are all sim])le, ambulatory. 



One specimen from Cerros Island, Lower California, was collected 

 by Mr. A. W. Anthony at a depth of 20 fathoms.
