posteriorly ; along the lateral margins and across the posterior 

 border there is a series of small -white blotches, about 2 to 3™"" in 

 diameter, the posterior ones smaller. The legs and chelipeds abova 

 are red, variegated with black and white spots, the black markings 

 being most abundant on the posterior legs ; the anterior ones and 

 the chelipeds being more red ; the first joint of the chelipeds is 

 mostly red, with the black and white marks only at the edges ; the 

 second and third joints on all the legs are red with black edges, 

 without spots. The chelae are mostly yellowish, becoming white at 

 the tips and reddish at the joints ; the last joint of the other legs is 

 yellow. All the legs are white beneath, except on the last three 

 joints. Abdomen dark purplish brown below, whitish above ante- 

 riorly. Eye-stalks colored like carapace above, light red below. —

Most of the specimens are much brighter colored than the above, 

 especially when the adherent dirt is removed. The larger males 

 usually have a large amount of red on the back of the carapace and 

 chelae. 



The variations in this species seem to be less than in many others 

 of this family, 



* The first ten series of measurements were made by Professor S. I. Smith 

 from specimens collected by the " Albatross," in 1884. The others are by the 

 writer.
