Caraquwe HlUjIiihi hnnulcr than long^ (jfcaiest wuUk <it (he antepenult 

 tooth of the lateral mart/in; tultet'eles prominent. 



Thia species is analogous to 0. angusta A. Milne- Edwards of the West 

 Indies in its narrow carapace, but whereas in C. angmta the greatest 

 width of the earai)a(;o is midway of its length, in tiaussurri the greatest 

 width is between the ante[)enult teeth of the lateral margin. Caiapaco 

 slightly broader than long, almost cirenlar, exclusive of the ])ostero- 

 latei'al limb, which has a subrectangular outline; two well-marked 

 grooves form the lateral boundaries of the (lardiac and gastric I'egions. 

 Tubercles of the carapace conical, and disposed as follows: Gastric 

 region with two large median and two smaller lateral in advan(;e of 

 thes(^, ami about (ughteon very small; cardiac with one central larger 

 surrounded by six smaller; branchial region with about fifteen large 

 and more than that number of small; intestinal region with six in two 

 lines diverging ])osteri()rly; hepatic region with live or six v(5ry small 

 depressed tubercles. The surface of the tubercles is densely granu- 

 hited; the space between them is covered with isolated granule*. 

 Margins of the front slightly raised; only a shallow groove separates 

 the snperior border of the antennulary fossie from that of the orbits. 

 The lateral border of the carapace has live or six small tubercles on
