Eostrum flattened and of moderate breadth, with the margins usually spinose. 

 Carapace with pubescent transverse strise ; the surface usually unarmed, with the 

 exception of the anterior gastric area ; the cardiac area not prominent. Abdominal 

 segments unarmed. 



The members of this genus occur chiefly in shallow water, but certain species are 

 found at considerable depths ; they live commonly on rocky ground, or among Corals 

 and Sponges, and swim backwards in the water by a rapid jerking movement of the tail. 

 The distinctive characters are in many cases so slightly marked that it is extremely difficult 

 to decide whether the specimen in question is entitled to rank as a species or merely as a 

 variety. The fact that in some species the merus of the external maxillipedes is shorter 

 than the ischium, while in others it is longer, serves to show that generic characters based 

 on the form of this joint must, in the Galathodea at least, be regarded with suspicion. 

 The supraorbital spines so prominent in the genus Munida are visible at the base of the 

 rostrum in most of the Galathese, but they are of small size, and in most cases are 

 associated with other lateral rostral spines.

Habitat.— Station 212, in the Celebes Sea; depth, 10 to 20 fathoms; bottom, sand. 

 Two males, and a female with ova. 



This species is characterised by the length of its rostrum and the brilliancy of 

 its colour markings, which are arranged in the form of purplish longitudinal bands on 

 the trunk and chelipedes. The rostrum is more than half the length of the remaining
