924 CRUSTACEA. 



in the Gammarinae, much more finely denticulated; and below this, to 

 one side, there are a few spines, and an oblong cluster or line of setae. 

 The usual prominence exists on the outer side ; but the palpus is 

 wanting. The inner maxillae have a two-jointed palpus. The 

 first and second caudal stylets have the branches slender acuminated, 

 and end in an acute point without a distinct spine for the termination. 

 The third pair has but a single branch, and this is without hairs, 

 rather short, subconical, a little reflexed at apex, and ending in two 

 very short spines, only seen under a high magnifier. 



This genus is near Leucothoe in its outer maxillipeds, the very 

 short third joint of the superior antennae, and many other characters; 

 and the absence of mandibular palpi seems not in this case, to be a 

 characteristic of so high importance, but that the genera may be 

 placed in the same subfamily.
