The tliiu'elluiii consists of fourteen urticulutions, chcIi of wliich 

 carrit's three or four setoe on tlie upper distal margin. 



The second antennse have the first joint stout, and about twice 

 as long as broad ; second and third narrower, but equal in length 

 to the first; fourth joint nearly equal in length to the two pre- 

 ceding combined. Flagelluni with nineteen articulations ; the 

 third joint is much shorter than those preceding or following, 

 excepting the last two at the tip. 



Mandibles short, stout, the upper third strongly bent inward, 

 cutting margin with four or five denticles, which are subtended 

 below by a series of flat, broad based spines, they taper gradually 

 to acute points. Molar tubercle close to the denticles well 

 defined, especially below. Palp about equal in length to the 

 mandible, with three subequal joints. 



First maxillae with inner lobe rather stout and tipped with four 

 long pectinated spines, the outer lobe carries twelve or more 

 rather slender simple spines, which taper rapidly to acute points. 

 Second maxilliie with the inner lobe twice as long as broad ; the 

 upper inner margin and the distal extremity are armed with 

 pectinate spines ; the outer lobes are tipped with long unbranched 

 setse. 



Upper portion of the second joint of the maxillipedes shorter 

 and broader than the lower, the outer margin is strongly convex, 

 the inner straight with a 

 short filament about the 

 middle ; the apical margin 

 and the external distal sur- 

 face carry numerous short 

 pectinate spines; the joints 

 of the palp are peculiar in 

 shape, as will be seen in the 

 accompanying figure. 



The first three pairs of 

 pleopods have the peduncle 

 armed on the interno-distal 

 angle with three or four 

 spines. The inner ramus 

 of the first is conical in 

 outline and shorter than 

 the outer ; the latter is 

 oblong with almost straight 

 sides, pointed proximally 

 and slightly convex dis- 

 tally. Outer ramus of second pair oval ; inner similar in shape 

 to that of the first, but longer and broader. The stylet is a little 

 longer than the ramus ; it is comparatively broad and of equal 



Right Maxilltpbde.
