182 Mr. R. I. Pocock on 



Legs smoother, the granules on the femora scarcely percep- 

 tible ; tarsi spined as in Sc. Gregorii, but one of the setfe 

 on the apex of the lobe, especially noticeable on the third 

 and fourth, thickened and spiniform, though with a filiform 

 tip; it thus approaches the completely spiniform condition 

 that is met with in Sc. exitialis, Poc, and Sc. arabicus, 

 Kraep. 



Pectinal teeth 15-16. 



Measurements in millimetres. — Total length 100; length of 

 carapace 15*3, of tail 50"5 ; length of segment 1 + 2 18; 

 length of hand-back 10'5, of movable digit 16; width of 

 hand 14-8, height of hand Q'b. 



A smaller male example taken with the above, and measur- 

 ing 96 milliin. in length, with the carapace 14 and the tail 

 49 — that is, just o^ times the length of the carapace — has 

 16-17 pectinal teeth, but the digits are normally constructed. 

 This example has evidently not attained its full complement 

 of sexual characters. Mr. Lort Phillips, however, picked up 

 the isolated pincers of a large male, which show that these 

 appendages are modified in this sex in the same way that 

 they are in exitialis and Gregorii — that is to say, the movable 

 digit is furnished with one long triangularly tuberculiform 

 tooth, which closes behind a smaller though somewhat 

 similar tooth on the immovable digit. These fortunately 

 recovered fragments show, moreover, that the species evidently 

 reaches a larger size than one would suppose to be the case 

 from examining only the two entire specimens; thus the 

 hand-back is 11'5 millim. long, the movable digit just 19, 

 and the width of the hand 16"3. Thus a simple calculation 

 from the measurements of the carapace, abdomen, and tail of 

 the smaller male, as compared with the measurements of its 

 hand, shows that the male to which these pincers belonged 

 probably exceeded 120 millim. in length.

A large number of specimens of this handsome species, 

 which has a wide range in East Africa, and occurs also in 

 Socotra (7. B. Balfour ^ Mus. Brit.), were obtained.
