6 STALK-EYED CRUSTACEA. 



Leptopodia debilis has been found to the northward of Panama as far as 

 the noi-thern extremity of the Gulf of CaUfornia, hat. 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. Z. sagittaria has been recorded 

 from as great a depth as 814 fathoms.t

The carapace is coarsely granulated and furnished with a few scattered 

 setaB ; 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-
