moulted, and which carries on its dorsum a small anemone, with a 

 bivalve shell interposed (vide Alcock, t. c. p. 279). The right 

 hand is much swollen in the two males. Mr. Alcock describes 

 both edges of the merus of 1st aud 2nd legs as being densely 

 pubescent in the male ; in these only the posterior edge is so, as 

 with the pro- and carpopodite. 



The base of the anemone rests directly on the shell; but, the 

 latter being only half the size of the anemone's base, it follows 

 that the outer edge of the base projects beyond the shell on every 

 side. Between this part of the base and the dorsum of the 

 Dorippe is found a circular flattened ring, with a wrinkled surface ; 

 with the appearance and consistency of mud supported by a few 

 scattered fibres. 



There is also another female from Malacca, which carries an 

 anemone. There is no shell interposed between the base of the 

 anemone and the crab, but only what appears to be the operculum 

 of a large Gastropod. The circular flattened ring mentioned above 

 is evidently the remains of a similar structure.
