This large species is generally reddish-brown, dull orange- 

 brown, or terra-cotta color above, more or less mottled with 

 orange, and with the frontal tubercles and edges of the carapace 

 lighter orange-red. First abdominal segment bright orange, often 

 mottled with purplish, and marked by two large, round spots of 

 bright reddish-purple, or lake-red, surrounded by orange, and 

 joined together anteriorly under the edge of the preceding seg- 

 ment. Succeeding segments dull orange or brick-red, mottled with 

 darker tints; telson and caudal fins (uropods) brownish-yellow, 

 spotted beneath with light brown, pale at the tips. Legs orange 

 with faint purple annulations at the joints and covered with small, 

 round, dark purplish-blue spots, with larger blotches of the same

 and more orange. The larger specimens are duller and darker in 

 color. 



The large male, described below, when recently dried and not 

 much changed in color, has the dorsal surface, in general, dull 

 reddish brown and orange-brown, with a large patch of deep red
