of anterior feet, one inch and four and a half lines ; length of hand, 

 seven and a half lines ; length of second pair of feet, one inch and 

 eight lines; length of third pair of feet, one inch and two lines; length 

 of posterior feet, one inch. 



The carapax is smooth and naked. The cardiac region is very 

 slightly tumid, and in younger individuals, it has at centre a minute 

 tubercle, which is wanting in the largest, and there is in all a trace of 

 a tubercle between this and the lateral spine. The margin of the 

 pterygostomian region has three or four small teeth. The outer 

 angle of the first joint of outer antennae is subacute. In an under 

 view, the peduncles of the eyes are visible for more than twice the 

 distance they are in an upper view. The palpus of the outer maxil- 

 lipeds has a re-entering angle on outer margin below the apex of the 

 long joint. There are two or three setae to apex of peduncle of eyes.
