Heterophrynus cervinus, sp. n. (PL VIII. fig. 1.) 



Colour nearly black, legs and lower surface ferruginous. 

 Carapace of normal form, the cephalic region coarsely 

 granular, the posterior portion with about three radiating 

 rows of granules, the rest smooth ; the anterior border straight, 

 finely denticulate, the median tubercle, which is high and 

 bears two tubercles on its summit, separated from the anterior 

 border by a space which equals half a diameter ; distance 

 between the lateral eyes considerably less than half the 

 median length of the carapace. 



Mandibles finely granular, a small terminal tubercle. 

 Chelce. — Coxae finely granular internally, more coarsely 

 granular behind, the rest smooth ; trochanter smoothish in 

 front, with a row of fine denticles above and four spines 

 below, three on the inferior edge, of which the median is 

 very long, and one at its distal angle ; femur less than twice 

 the width of the carapace, thickly and coarsely granular, 

 armed with five spines above, the first two rising from the 

 same base, the third the longest, the fourth and fifth decreasing 

 in length, the lower edge armed with four spines, which 

 gradually decrease in length from the first to the fourth ; 

 tibia coarsely granular, longer than the femur, with only one 

 spine behind the three principal ones on the upper edge, the 

 last spine much longer and stouter than the penultimate, 

 lower edge armed with 5 spines, of which the third from the 

 end is the longest, although the last is longer and stouter than 

 the one that precedes it ; tarsus granular outside and inside, 

 the first spine long, considerably more than half the length 

 of the second. 



Legs long ; femur of first three and a half times the width 

 of the carapace, that of the second about twice its width, that 

 of the third a shade longer than that of the second, which is 

 longer than that of the fourth (for the rest see measurements). 

 Abdomen. — Terga with a row of granules along posterior 

 border ; for the rest the terga are nearly smooth, there being 

 only two or three granules on each side of the middle. 

 Sterna sparsely granular. Genital operculum coarsely 

 granular. 



Measurements in millimetres. — Total length 31 j width of 

 carapace 17, median length 11, distance between eyes 4. 

 Chela : length of femur 30, width 2'5 ; length of tibia 34*5, 

 of tarsus 9*5, of digit 6. Legs : femur of first 59, of second 

 33'5, of fourth 32 ; tibia of second 35*5, of third 39, of fourth
