Tlii.s species is readily distinguished from the foregoing. The rostrum 

 is narrower and pointed, though hollow underneath. The basal anten- 

 nal Joint has a small acute tooth projecting forward from its antero- 

 externnl angle; the laminiform margins are very i)rominent, esj)ecially 

 the inner one, which is deepest at about the middle of its length, at 

 which point there is a transverse crest on the Joint. The partition 

 between the antennular fossa' is i)rolonged downward at the middle in a 

 sharp tooth. The two small tubercles present in the preceding species 

 at the extremity of the epistome are in /*. JameUigera much enlarged, 

 forming large triangular laminiform i»roJcctions, the anterior oiu' not far 

 behind xhe orbit, the posterioi- one lower down. The hepatic jjrojection 

 forms a slender spine. The angle of the buccal cavity is cristate and 

 the pterygostomian crest beats a large tooth in the middle of its length. 

 At the base of each cheliped there are two thin plates projecting down- 

 ward and inward, and two on the sternum at the extremity of the male 

 abdomen. The sternal plates are broad, thin, bearing spinules, their 

 ])osterior margins turned downward and overlapping the next plate. 

 The coxal Joint of each ambulatory leg is furnished on the lower side 

 with a cup-shaped expansion. 



Measurements. — Length (of male), 18 mm.; width, 12.5; length of 

 cheliped, about 18. Length (of lemale), 20; width, 10; length of 

 cheliped, 23; length of first ambulatory leg, 00; length of merus, 20;
