Total length 81, carapace 15, tail 50 ; width of haud 12 ; length of movable digit 13, of hand-back 8. Loc. Jifa Uri inland from Zeyla (R. 31. Hawker). In British Museum. Differing from P. colei and P. peeli in the characters pointed out below (p. 62). PANDINUS PUGILATOR POC. Cf. supra, p. 52. PANDINUS MILITARIS, sp. n. Scorpio bellicosus, L.

Terga finely granular laterally. Tail a little more than two and a half times as long as the carapace, the inferior keels on segments 1-3 quite smooth, those on 4th at most slightly rugose; superior and superior-lateral keels of all the segments granular or weakly denticulated ; superior surface of 1st granular, of 2nd less so; width of 1st exceeding length of 3rd, almost equal to that of 4th ; 5th about twice as long as wide. Chelce: humerus granular above at least on its basal half, smooth below; brachium almost entirely smooth, its anterior side weakly granular above, more coarsely below ; hand wide, its width in adult exceeding length of 3rd and 4th caudal segments, inner edge smooth, upper surface smooth, finely reticulated, a few low tubercles just above the keel of the underhand aud at the base of the immovable digit; external portion of upper surface rising vertically above keel of underhand ; thickness of hand at the front equal to length of 4th caudal segment. Lower side of hand granular distally, scarcely crested. Pectinal teeth 12-15. Measurements in millimetres (of type). Total length 112, carapace 19, tail 51 ; width of hand 16-8, underhand 10-5. Loc.
