72 Mr. C. Spence Bate on a new Genus of Macrura. 
hairs stand at the dactyloid articulation and reach beyond the 
extremity of the dactylos, which is formed like the pollex and 
tipped with three straight, stiff, and ciliated hairs. 
The second, third, and fourth pairs resemble the. first, 
being perhaps rather more slender; and the fifth pair (0) are still 
shorter and differ from the preceding chiefly in terminating 
in a non-chelate extremity free from hairs, excepting a simple 
one on the dactylos, a ciliated one on the carpus, and another 
on the meros. 
The pleopoda are short and feeble and have not been 
properly examined. 
The branchial plumes are numerous, but in consequence 
of having been preserved in a desiccated condition they 
are not capable of being carefully noted; but there appears 
to be a series of arthrobranchie and pleurobranchie, which 
probably may be arranged as follows :—

The general aspect of the animal to casual observation is 
more that of a Crustacean belonging to the Brachyura than 
to one of the Macrurous division. 
The broad and quadrate character of the carapace and the 
narrow and folded condition of the pleon are features of the 
Brachyura type; but, on the other hand, the long and 
sweeping branches (ecphyses) attached to the ambulatory legs, 
which are themselves apparently too short and feeble to be of 
much use, and theimpertect conditionof the chelate appendages,
