and Santa Cruz (115 fathoms), but these by no means indicate the extreme limit of its 
bathymetrical range ; specimens having been recently received by the British Museum 
from Captain E. Cole, taken off Jamaica in 600 fathoms, and in the Mona Channel, 
West Indies, in 814 fathoms.

Fully grown specimens were obtained at Madeira, and St. Vincent, Cape Verde Islands, 
also smaller examples at Bahia in shallow water, 7 to 20 fathoms. Another young female 
was dredged at Barra Grande, south of Pernambuco, in 30 to 350 fathoms (Station 122), 
in lat. 9° 5' to 9° 10' S., long. 34° 49' to 34° 53' W.

This genus, which is nearly allied to Leptopodia , is distinguished by its uneven and 
tuberculated carapace, the exposed flagella of the antennae which are visible at the sides 
of the rostrum in a dorsal view, and by the very considerable development of the median 
distal spine of the merus of the ambulatory legs. 
In Metoporaphis forjiculatus, which is the only species I have examined, the chelipede 
differs markedly from that of Leptopodia, the palm (in the adult) being much shorter 
than the dactyle and pollex, which are slender, gaping, incurved, and meet only at 
the tips. 
The ascertained range of this genus is from Charleston Harbour (whence the type was 
obtained) southward to Barra Grande on the Brazilian coast ; the species are apparently 
of very rare and local occurrence. But two have been described, which must be regarded 
as doubtfully distinct one from the other; Metoporaphis calcarata (Say), and Metopo- 
raphis forjiculatus, A. Milne Edwards.
