IJeterophrt/nus armtger, sp. n. 



Normally coloured and grnnulnr. Ocular tubercle and 

 lateral eyes exceptionally high. 



Chclce shorter and stouter than in any species hitherto 

 described ; trochanter normally spined ; femur covered above 

 with five spines, the fifth standing near the middle of the 

 distal half of the segment ; the lower side armed with five 

 spines, the first and second long, not very unequal, the third 

 small, slender, about half the length of the second, and a 

 little less than its own length from it, and about as long as 

 the fifth, the tourth noticeably shorter than the second, the 

 fifth near the middle of the distal half of the segment ; tibia 

 armed above with six spines, the first standing about midway 

 between the base of the segment and the proximal of the 

 three long spines ; fifth and sixth spines small and slender, 

 pubequal, both of them shorter than the first ; lower side of 

 this segment armed with six spines, of which the first, 

 second, third, fifth, and sixth represent the second to the 

 sixth of longicornis, chiracanthus, and the first to the fifth of 

 cervinus, the fourth from the proximal end being super- 

 numerary and inserted between the normal third and fourth 

 spines; the penultimate spine of this series is as thick and 

 about twice as long as the last, and slightly thicker than and 

 almost as long as the third spine from the distal end, which is 

 the longest of the series. 



Hand spined as in the other species, the distal half of the 

 external surface quite smooth, except the edges, which are 

 very finely denticulated, the proximal half up to the root of 

 the long spines dull and studded with coarse granules. 



Meaburements in luillimetres. — ^. Total length 34 ; width 

 of carapace 16"5, its median length 11"5; Icngtii of femur of
