AETHEOPOD FAUNA OF THE "WEST INDIES. 535 



terga fusco-ochraceous, fuscous for the most part in front, ferru- 

 ginous behind. 



Carapace rather finely granular ; distance between the lateral 

 ej'es a little more than half the median length of the carapace; 

 each tubercle about equidistant from the anterior and the lateral 

 border, this distance being a little less tban half the distance 

 between the eyes ; the frontal area nearly vertical at the sides, 

 in the middle sloped at an angle of from 35 to 40 degrees, the 

 median eyes thus looking forwards and upwards, the tubercle of 

 these eyes normally high and separated from the anterior border 

 by a space which is a little less than its longitudinal diameter; 

 this border lightly emarginate, the teeth much, stronger laterally, 

 slightly upturned, the apex of the inferior median spine turned 

 forwards and just visible when the carapace is viewed from 

 above. 



Terga sparsely granular. 



Mandibles with a few granules above and a large external 

 tubercle. 



CJielce moderately long and robust, the distance between the 

 lateral eyes about two-thirds of the length of the femur and 

 almost as long as the tarsus ; the latter smooth externally, the 

 femur and tibia coarsely, but not closely, granular : spines 

 moderately long, the longest on the tibia greater than the 

 width of the segment, but less than the distance between the 

 lateral eyes ; the longest on the femur equal to the height 

 of the segment, but much less than the distance between the 

 eyes. 



Legs moderate : femur of the 1st a little shorter than twice the 

 width of the carapace, that of the 2nd longer by about a quarter 

 of its length than the width of the carapace ; femur of the 3rd 

 a little longer than that of the 2nd, which equals the femur and 

 patella of the 4th ; tibia of the 2ad about equal to the femur 

 and more than twice the protarsus ; tibia of the 3rd a little 

 longer than the femur and more than twice the protarsus ; 

 the tibia of the 4th noticeably longer than the femur, the 

 second and third segment, taken together, a little more than 

 half the length of the first and almost equal to the protarsal, 

 the second tibial nearly two-thirds the length of the third and 

 a little more than half the distance between the eyes.
