pair of legs ; also, one or two spines on the antero-lateral region, ante- 

 riorly. The outer maxillipeds are hairy throughout. The inter-an- 

 tennary septum is produced into a long spine, and the margin behind 

 the fossettes, next to the base of outer antennae, is reflexed as in the 

 E. septentrionalis.

EURYPODIUS AUDOUINII (Edwards and Lucas). 



We refer here, with hesitation, a specimen (male), which is in an im- 

 perfect condition in our collections, owing to its having been taken while 

 the shell was in the soft state. It has the fifth joint of the eight pos- 

 terior legs about as long as the fourth, or a little shorter in the two 

 posterior pairs. The hand is stout and tumid, and the finger has a 

 rounded prominence on the inner margin, inside of middle, which is 

 thin and denticulate like the rest of the edge, and not a rounded 

 tubercle like that of the septentrionalis. The surface below is covered 

 with an exceedingly short but rough down; the legs are nearly bare. 

 It is probably from Nassau Bay, Fuegia.

This species differs from the preceding in having the fingers of the 

 hand without any appearance of a tooth-like prominence on the inner 

 edge, the edges being simply and evenly denticulate. Moreover, the 

 margin of the antennary fossettes behind, is not reflexed adjoining the 

 immoveable basal joint of the outer antennae. 



A specimen an inch in length has the following characters. The 

 beak is about one-fourth the whole length of the carapax; it is flat- 

 tened above, but the flat surface is placed a little obliquely. The
