450 ON THE AUSTRALIAN BRACHYURA OXYRHYNCHA. 



Adams and White's figure was obviously from a young specimen. 

 The specimen from Darnley Island in the Hon. William Macleay's 

 collection, has the carapace half an inch in length ; it differs from 

 the figure in the voyage of the " Samarang" in the rather greater 

 relative length of the anterior limbs, and the less relative breadth 

 of the front, and is probably an adult specimen of the same 

 species.

This species is liable to considerable variation ; there are two 

 extreme varieties connected by intermediate forms from the same 

 localities. Variety a. has the characters of Adams and White's 

 description and figure ; variety b. has end of the ridges above the 

 eyes produced into an elongated spine directed forwards and 

 upwards ; a third spine directed upwards and backwards from 

 the point of bifurcation of the dorsal carina, and a fourth on the 

 cardiac regions placed nearly vertically ; the outer border of the 

 hand is produced at its proximal end into a prominent rounded 

 lamella.

Adult specimens which I refer to this species have the intra- 

 ocular space relatively much smaller than in Adams and White's 

 figure, the front more prominent, and the spines on the outer 

 surface of the hand longer and more acute ; but young specimens
