Show 60 MR. C. V. A. PEEL AND OTHERS ON [Jan. 23, smooth. Again, the 2nd and 4th abdominal sterna are finely granular in the middle; and, lastly, the vesicle is more strongly inflated, its width considerably exceeding its height and being equal to that of the 4th caudal segment. In the female the width of the vesicle is scarcely greater than its height and less than the width of the 5th segment. Pectinal teeth 11-13 ( d 2 )• Total length ( d ) 82 mm., carapace 13-5, tail 38, underhand 8-5, width of hand 12. PANDINUS PEELI Pocock. Cf. supra, p. 53. PANDINUS HAWKERI, sp. n. Colour of carapace and palpi yellowish brown ; tergal plates and tail reddish brown ; vesicle brow7n with yellow lines ; legs entirely pale yellow, abdominal sterna testaceous. Carapace smooth, polished; terga also smooth, punctured along the posterior margin, the last very weakly granular laterally, the crests obsolete. Sterna, with exception of the last, smooth ; the last obsoletely crested, but mesially closely granular. Tail short, only a little more than tw o and a half times the length of the carapace, which is almost as long as its first three segments; the inferior median keels absent on segments 1-5, the inferior laterals present, smooth on segments 1 and 2, granular on 3 to 5, the area of the lower surface of the tail between them granular as in P. colei; superior and superior-lateral keels of tail weak, punctured, but not granular ; sides of tail smooth ; upper surface at most very sparsely granular, except along the posterior edge of segments 1-4, where there is a series of denticulit'orm granules ; vesicle strongly punctured and setose beneath, but scarcely granular, its width exceeding its height. Chelce: humerus smooth below and behind, the crests on its upper and anterior surfaces coarsely granular, its upperside sparsely granular in the basal half ; brachium smooth, except for some minute granules in front and some coarser ones along the anterior inferior crest: hand moderately wide, its width equal to three-fourths the length of the carapace ; upper surface granular on the external slope above the strong keel of the underhand; the rest of the upper surface nearly smooth and polished, beset with a fine reticulation of ridges which are almost obsolete in adult, coarser in young ; inner edge almost smooth, punctured, lower surface sparsely and weakly granular towards the base of immovable digit; immovable digit with its basal width less than half the length of its biting-ed^e; movable digit shorter than carapace, exceeding width of hand, equal to length of 3rd and 4th caudal segments. Legs smooth ; protarsi of 1st and 2nd with one posterior apical spine; tarsal lobes with two spines ; lower surface of tarsi with one anterior and three posterior spines; anterior claw much |
