6 STALK-EYED CRUSTACEA. 
Leptopodia debilis has been found to the northward of Panama as far as 
the northern extremity of the Gulf of California, lat. 31° 22’ N. A similar 
or possibly identical form, L. modesta A. M. Edw.,* occurs on the coast of 
Chile. 
The bathymetrical range of Leptopodia debilis, so far as known, extends 
from low-water mark down to 29 fathoms. JZ. sagiétaria has been recorded 
from as great a depth as 814 fathoms.

The carapace is coarsely granulated and furnished with a few scattered 
setae; there are two erect blunt spines in the median line of the carapace, 
one of them arising from the gastric region, the other from the cardiac 
region ; in front of the gastric spine is seen a transverse row of four or five 
tubercles, which are somewhat larger and more prominent than the granules 
which cover the general surface of the carapace ; from the middle of each 
branchial area there springs a spine which is longer than those in the median 
line, and curved slightly forward at the tip; there is also a smaller lateral 
spine below and a little in advance of this; the hepatic area bears a short, 
blunt, granulated spine on its most prominent part, and three or four promi- 
nent tubercles on the angle which divides it from the pterygostomian area ; 
the antennal spine is very long, reaching some distance beyond the rostral 
horns, while the interantennular and lateral rostral horns are of about an 
equal length ; the supraocular spines are well developed, and, like the anten- 
nal spine and the three horns of the rostrum, have a distinctly granulated 
surface ; the postocular spines are even more coarsely tuberculated, and 
when viewed from above their margins are laciniated. The lower face of 
the basal segment of the antenna is granulated, and furnished beside with 
two to three spinules; the outer maxillipeds are also granulated. The sur-
