pair of legs ; also, one or two spines on the anterolateral .region ante- 

 Sy Ine outer maxillipeds are hairy throughout. The .nter-an- 

 tennary septnm is produced into a long spme, and the m arg,n behind 



the fossettes, next to the base of onter antenna, is reflexed as u. the 

 K septentrionalis.

Eurypodius Audouinii {Edwards and Luccui). 



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 septentrional Is. The surface below is covered 

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

 It is probably from Nassau Bay, Euegia.

This species differs from the preceding in having the lingers 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 antenna?. 



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 pTaced a little obliquely. The
