 broadens distally, second and third joints subequal but second much 

 stouter, third joint tapering sHghtly and terminated by several slender 

 spines ; cutting edges denticulated ; molar tubercle prominent ; several 

 spines on spine row. Lower lip with outer plates large and widely 

 separated, inner plates large and oval ; mandibular processes not 

 large. First maxillae with inner plate oval and large, provided with 

 single spine apically ; outer plate moderately slender with distal

 with second joint slender and tapering, with few spines on outer 

 and inner margins and apex. Second maxillae with outer plate 

 bearing single plumose spine apically and several simple ones on 

 inner margin, rather slender and shorter than inner plate which is 

 very broad and of oval form, with a few setae on inner margin. 

 Maxillipeds with inner plates small and bearing 3 odontoid spines 

 on transverse distal margin ; outer plates rather large with outer 

 and inner margins parallel and with apical margin rounded, bearing 

 long setae on inner margin; palp 4-jointed and provided with un- 

 guiform spine apically ; third joint with many setae apically where 

 it is broader than at base ; fourth joint with short setae on inner 

 margin ; second joint provided with flat laminar process along entire 

 inner margin which bears long slender setae. 



First gnathopods with subtriangular epimeron considerably higher 

 than long; second joint moderately long and of uniform thickness, 

 provided with group of spines at antero-distal angle : third joint short ; 

 fourth joint subtriangular with setae along posterior margin ; wrist 

 triangular, broader than long with setae on posterior margin ; hand
