//. saxatilis and H. woodmasoni ; but differs entirely from the 

 latter in possessing the large expansion at the distal end of the 

 tibial apophysis. Total length 23 mm. 



Loc. Burma: Zigon and Minhla in the Tharrawaddy district 

 (Oates). 



98. Hypoctonus rangunensis, Oates, J. A. S. B. lviii, p. 18, 1889 

 (Thelvphonus) ; Kraep. Abh. Ver. Hamb. xv, p. 46, 1897 ; id. 

 Tierr., Scorp. etc. p. 232, 1809 (Hypoctonus). 



<3 . Colour as in H. sylvaticus, but in other respects more nearly 

 approaching H. saxatilis, the femur of the chela being granular 

 above and below, practically as in that species. Tibial apophysis 

 long as in the two species named, but different in shape, the posterior 

 border almost entirely straight, only very slightly sinuous and 

 unarmed ; anterior border also very nearly straight, only very 

 slightly sinuous, but armed with about half a dozen small denticles, 

 the apex obliquely truncate, tridentate, a slight swelling on the 

 anterior edge of the apophysis just before the apex. Inner edge 

 of hand widely but not strongly convex, forming almost a straight 

 line with the outer side of the immovable finger, which is itself 

 almost straight, with scarcely a trace of the sigmoid curvature 

 observable in H. saxat'lis and H. sylvaticus. 



2 . Very like that of H. saxatilis, but differing in the colour of 

 legs; first abdominal sternum with very nearly the same shaped 

 semilunar impressions. 



Total length up to 28 mm. 



Loc. Burma : Kangoon and the neighbourhood (Oates). 



9. Hypoctonus formosus, Butler, A. M. N. H. (A) x, p. 203, 

 ' pi. xiii, fig. 4, 1872; Stoliczka, J. A. S. B. xlii, p. 137, pi. xii, 

 fio-. 4, 1873 ; Oates, op. cit. lviii, p. 14, 1889 (Thelvplionus) ; Kraep. 

 Abh. Ver. Hamb. xv, p. 48, 1897; id. Tierr., Scorp. etc. p. 231, 

 1899 (Hypoctonus) : angustus, Stoliczka, J. A. S. B. xlii, pt. 2, 

 p. 134, 1873 (in part) (Thelvphonus). 



<S . Colour of legs as in 11. saxatilis, except that those of the first 

 pair, instead of having 1he femur, patella, and tibia black, have 

 the patella and tibia a dark brownish red and only slightly darker 

 than the rest of the segments. Chela' most resembling those of 

 //. rangunensis, but the femur very much more thickly and coarsely 

 granular below, even more so than in H. saxatilis; spine on lower 

 side of femur noticeably stronger than in 11. rangunensis, very much 

 stronger than in //. saxatilis. Tibial apophysis long and slender, 

 straight and parallel-sided, without trace of apical enlargement, 

 \\\\\\ three apical teeth. Inner edge of hand much more prom- 

 inent than in //. ranr/unevsis, more like that of 11. saxatilis, hut the 

 prominence more distinctly angular, and not so rounded ; im- 

 movable finger much broader at the base, almost as broad as long. 



2 . First abdominal sternum very different from that of 11. wond- 

 masoni, rangunensis, and saxatilis, without any large circular or 

 crescentic pits, but furnished in its anterior half with a pair of 

 small round holes, sometimes sunk in a common depression,
