STALK-EYED CRUSTACEA i6i 



spines or teeth on antero-lateral margins are short. There 

 are two or three tubercles on superior margins of orbit, 

 not acute. Lobes of the front prominent, rounded, 

 crranulated ; there is a transverse series of long hairs 

 above the margin. Lower margin of orbit not spinous. 



Walking legs studded above with scattered granules 

 smaller and sharper than those of the hands and carapace. 



Granules and spines bright ruby red ; upper surface of 

 carapace and feet covered with a cream coloured velvet- 

 like pubescence. 



Range. — St. Thomas, Florida ; in deep water.

The body and the legs are covered above with down, 

 except upon the fronto-orbital regions. The carapace 

 is about seven-eighths wider than long, very wide behind 

 and convex ; the regions are slightly marked ; the test 

 is rendered rough by scattered tubercles of variable 

 size, and more numerous upon the gastric and hepatical 

 regions. The frontal region is continued with the orbit, 

 and they are without teeth or spines, so constituting the 

 anterior border of the carapace, which is prominent, wide, 

 naked, and ornamented with very small tubercles ; a 

 depression in the form of a canal separates it from the 

 rest of the carapace ; there is no notch where the front 

 joins the orbits, and the median notch of the frontal 

 contour, which is straight or slightly convex, is very 

 shallow. At the external angle of the orbit the border 

 continues a little backwards upon the antero-lateral edge ; 

 posteriorly, the antero-lateral border is almost parallel 

 with the axis of the body, and is armed with three small
