Material examined.

6661, 147 m
, 8 spec. (MZUSP-13868); 37 spec. (MZUSP-13858); st.

Diagnosis.
Shield longer than broad; rostrum short, rounded, not exceeding lateral projections. Ocular peduncles strong; corneae dilated; ocular acicles long, triangular with acuminate tip. Antennular peduncles overreaching ocular peduncles by length of terminal segment. Antennal peduncles overreaching ocular peduncles by approximately half length of terminal segment. Right cheliped with fingers approximately one-third length of palm; dorsal face of palm and carpus with granules. Left cheliped smaller and more slender than right; carpus with dorsal and lateral faces compressed, slightly broader distally; palm with margins parallel and shorter than fingers, dorsal face finely granulated. Male with right sexual tube. Telson with posterior lobes almost symmetrical, separated by shallow median cleft; each margin with 2 strong corneous and articulated spines.
Distribution.
Western Atlantic:
United States
(Virginia, Carolinas, Florida), Antilles and
Brazil
(Rio de Janeiro and São Paulo).
Habitat.
Between 80 and
500 m
; on sand, mud and shell grit.
Remarks.
Forest & Saint Laurent (1968)
compared the material from the “Blake”, “Albatross” and “Calypso” expeditions, which was collected in different regions, and observed some morphological differences among specimens from those regions. The
56 specimens
of
C. sharreri
that we examined are morphologically closest to material from the “Calypso” (based on the illustration by
Forest & Saint Laurent 1968
: 152, fig. 124) due to similarities in form and proportions of the ocular acicles and the antennal and ocular peduncles.
