Flagollum with from nine (female) to twelve (male) ait iciilalioiis, 

 the tliird being much the longest. 



All the joints of tlu^ peduncle and the pi'oximal half of the 

 tlagellum are densely ciliated, and also exhibit numerous long 

 scattered setie. 



The cephalon is furnished with a spatuliform process ; this is 

 widely bifurcated at its base, and embraces the anterior portion 

 of the epistomial plate ; from the lower third its width gradually 

 increases to near the rounded summit. The process is equal in 

 length to the cephalon, and its projection anteriorly equals that 

 of the basal joint of the first antenme. 



Mandibles straight, moderate in size, the cutting edge bi- or 

 tridentate, with two or three stout denticles and several strongly 



curved spines at its inner 

 base. Molar tubercle dis- 

 tinct, attaining to the same 

 level as the apical denticles ; 

 the margin is encircled with 

 spinules. Palp three-jointed, 

 the second much the longest. 

 First maxillse subequal in 

 width; the outer lobe with 

 about ten slightly -curved 

 spines, some of which exhibit 

 Mandible. . from three to five minute

 maxillse hnve the lobes subequal in width, and attain to the same 

 leveh The inner lobe is 

 rounded at the apex, and 

 bears twenty or more pecti- 

 nated setge; the apices of the 

 outer lobes are obliquely trun- 

 cated, and tipped with numer- 

 ous stout set*. 



The maxilipedes have the 

 second joint tipped with 

 numerous pectinated spines, 

 and the inner border bears 

 a short filament, with a 

 dilated apex. Palpi five- 

 jointed ; the third shorter 

 than the one preceding or 

 following ; the last joint is 

 the longest ; the superior seti- 

 ferous lobes are rather low.
