Neio and Little Known South African, Solifuyce. 399 



the posterior tooth large and strong, preceded by a very small tooth 

 (in one jaw there is a minute tooth between these in addition) ; 

 anterior to the small tooth are a pair of thin keels, one on the inner 

 and one on the outer edge of the upper surface ; the inner keel is 

 sub-dentiform and directed upwards and inwards, the outer keel 

 forms a long low ridge directed upwards and in a line with the teeth 

 of the jaw. These two keels are very characteristic. 



Flagellum somewhat resembling that of sclateri but much shorter, 

 the apical part quite straight and terminating on each side of the 

 ocular tubercle almost in a line with its hind margin. At the 

 anterior bend the flagellum is strongly compressed laterally, but at 

 the basal end it is scarcely enlarged, although provided on the 

 median side with a small inflation (apparently corresponding to that 

 on the outer side of the basal enlargement of Solpuga) ; the basal 

 end protected by a row of stiff feathery bristles, which do not, 

 however, reach the apex of the jaw. The anterior half of the 

 flagellurn is minutely sulcate above and in front, the outer keel 

 bounding the sulcus being a continuation of the very high keel at 

 the anterior bend, as in sclateri ; in its posterior half, however, the 

 flagellum is cylindrical without trace of the keel. 



Measurements. Total length 20A- ; length of head-plate 3J, width 

 4 ; length of mandible 5, width 2 ; length of flagellum 3 ; length of 

 palp 15, tibia 4|, metatarsus + tarsus 4i ; length of III. leg 16 ; 

 length of IV. leg 24-|, tibia 6, metatarsus 4-|. 



Locality. Two males (dry, No. 1055) labelled " Walfish Bay," 

 Damaraland (Mr. Clcverlcy).

? . Colouration. Very similar in the markings to sclateri, but 

 much less deeply infuscate. Mandibles pale yellow, with only one 

 longitudinal infuscate stripe (corresponding to the middle one of 

 the three in sclateri), not marbled. Head-plate similar to that of 

 sclateri, differing only in having the marmorate markings much less 

 distinct, the whole central area thus appearing plain yellow to the 

 unaided eye. Terga and sides of abdomen uniformly pale infuscate, 

 the sides not darker than the terga ; the sides are paler and the 

 terga darker than the corresponding surfaces in sclateri, and the 

 three infuscate dorsal stripes are quite absent. Legs marked as in 

 sclateri, but the infuscation is a little paler, and the legs are pale 

 yellow distally. Malleoli not black-edged.
