REPORT ON THE BRACHYURA.

but is without distal spines or teeth. The ehelipedes (in the male) are moderately 
robust, and the palm is slightly turgid (as in Stenorhynchus). The ambulatory legs are 
slender and somewhat elongated ; the dactyli short and retractile. 
M. Milne Edwards has united Coryrhynchus, Kingsley ( — Podonema, Stimpson, nom. 
prseoc.) with Podochela, but it may be convenient to retain this term as a subgeneric 
designation for the species with a distally-rounded and (usually) hood-shaped rostrum. 
The species which have been enumerated by Milne Edwards, with one exception 
( Podochela vestitci, Stimpson, from California, Cape St. Lucas) inhabit the Gulf of Mexico 
and Caribbean Sea, where they are found in shallow water and in depths not exceeding 
60 fathoms (as at present recorded). 
By the Challenger researches, however, the range of Podochela riisei is extended 
southward to the Brazilian coast, and its bathymetrical range to (possibly) 350 fathoms.

Two males and two females were collected at Bermuda in shallow water, and a male in 
mutilated condition south of Pernambuco, Brazil (Station 122, 30 to 350 fathoms). 
These specimens have the tuberculiform prominences of the gastric region of the 
carapace less distinctly defined than in the specimen figured by Milne Edwards. In all 
of them the ridges upon the pterygostomian regions, defining the afferent channels to the 
branchiae are very distinctly developed.

Eyes slender and retractile. Praeocular spine usually wanting, postocular distinct. 
Basal antennal joint usually very slender throughout its length, not narrowing distally. 
In the typical species the margin of the carapace often forms a slight rim over the
