388 AituaJx of lln 1 South African Museum. 



carinate, nor angular ; the outer surface convex, sub-angular along 

 its middle, finely caniculate at base just under the upper edge ; the 

 teeth as in lanatus. Lower jaw curved slightly outwards and also 

 upwards, but much less strongly than in lanatus. In both upper and 

 lower jaw the apex is very blunt, but this is probably due to age and 

 wear. 



Spines on legs as in lanatus. 



Measurements. Total length 25 ; length of thoraco-abdomen 18, 

 width 13, height 12 ; median length of head-plate 4^, width 6f ; 

 length of mandibles 5, width 2f . 



Locality. A single ? from Worcester (J~. Lycctt, No. 1033).

diameters of the South African Species. Basal segmentation of 

 legs as in Ceroma and Solpuga, i.e., with two trochanter joints in the 

 II. and three in the III. and IV. legs. Tarsi of II. and III. legs 

 two-jointed, that of IV. leg four-jointed, the subungual appendages 

 small, not diverging. Tarsus of I. leg without claws in either sex. 

 Tarsus of palp very slightly movable in the ? (apparently immovable 

 in the single <? specimen), the metatarsus not scopulate, but pro- 

 vided below with 3 short outer and 1 (in the ? ) or 3 (in the $ ) 

 short inner spines, and generally also some much longer spines or 

 spiniforrn setse in a row with the short spines ; t metatarsus dis- 

 tinctly compressed from above and below, appearing sub-fusiform 

 when viewed from the side, being slightly thicker in the middle than 

 at the ends (fig. 10a). Ocular tubercle with several bristles in front. 

 Flagellum of $ with the basal enlargement flat, not turgid, pro- 

 duced posteriorly into the shaft and fixed to the inner side of the 

 mandibles behind the base of the terminal fang in such a manner as 

 to be partially movable in a vertical plane round the point of attach- 

 ment (as in Hexisopus). Upper lobe of rostrum (fig. 9c) not deflexed 

 at the apex but evenly pointed, as in Solpuga. 



DAESIA LEIPOLDTI, n. sp. 

 (Figs. 9-9c.) 



? . Palps with the metatarsus slightly but distinctly stouter in 

 the middle than at the ends, depressed from above and below ; 



* Prof. Kraepelin informs me that Daesia and Biton are identical. 



t The typical arrangement of these spines is shown in figs. 10a and lla.
