438 CRUSTACEA. 



Eostrum very short. Carapax mostly rough hairy. Eyes slender, 

 not shorter than anterior margin of carapax, much longer than base 

 or acicle of outer antennae, but shorter than base of inner; basal scale 

 much elongated and narrow, the outer margin arcuate and edged 

 with minute, slender teeth. Flagellum of outer antennae long 

 ciliate below. Feet of second and third pairs rough hairy in tufts, 

 rather stout. Anterior feet equal, hand short spinous and tufted 

 hirsute, subelliptical in outline, superior margin nearly straight, 

 inferior much arcuate and set with conical spines.

Chili. 



Length, two inches. The basal scale of the eyes is very peculiar 

 in its very elongate narrow form, and denticulate outer margin. The 

 male abdomen has four appendages on the left side, the first obso- 

 lescent, the rest with a small basal joint and a long narrow ciliate 

 termination. The ciliation of the outer antennae is long. 



The species resemble the Bernliardus cequimanus, as observed under 

 that species. 



GENUS DIOGENES, Dana. 



Annulum aphihalmicum rostriferum. Pedes ti subcheliformes. Manus 

 sinistra major ; digiti acuminati, apicibus calcarei. 



Ophthalmic ring bearing a rostrum. Fourth pair of feet subcheliform. 

 Left hand the larger ; fingers acuminate, calcareous at tips. 



The pointed fingers with calcareous tips ally the species to those of 

 Bernhardus ; but the left hand is much the larger, and the rostriform 

 appendage to the ophthalmic ring is peculiar. The acicle of the 

 outer antennae is broad, and often deeply furcate, the two processes 

 extending either side of the next joint.
