Ncio and Little Known South African Solifuyce. 395 



above, not attenuated distally, where it is as thick as in the middle, 

 the under surface without true spines or scopula. Basal enlarge- 

 ment of flagellum (figs. 13 and 14) protected by a row of stiff bristles, 

 turgid on the median side but flat on the lateral side, by which it is 

 immovably fixed to the inner surface of the base of the terminal 

 fang ; the basal enlargement produced upwards into the shaft (not 

 forwards as in SotytMja). Ocular tubercle with a number of fine 

 bristles, especially in front. Upper lobe of rostrum either evenly 

 pointed at the apex, as in fig. 13r (sclateri, incriuc), or the apex 

 unevenly pointed, the lower side being straight and the upper convex 

 (capcnse, fig. 156). 



CEROMA SCLATERI, n. sp. 

 (Figs. 13-13c.) 



3 Flagellum extremely long, reaching, when straightened out, 

 almost to the bind margin of the head-plate. Basal enlargement 

 pear-shaped, somewhat laterally compressed, deeply sulcate on its 

 anterior side, the sulcus bounded laterally by a high thin keel and 

 on the median side by a lower, thicker ridge ; the basal enlargement 

 situated at the base of the upper fang on its inner side and protected 

 on the median side by a row of long, stiff, feathery hairs which 

 reach to the apex of the fang. Basal portion of flagellum tapering 

 gradually upwards and then backwards into the slender filiform 

 shaft, which passes along the middle of the upper surface of the 

 mandible and on the lateral side of the eye-tubercle, behind which 

 it curves gradually towards the median line. The anterior sulcus is 

 continued backwards along the upper surface for some distance, 

 while the lateral keel bordering this sulcus may be traced almost 

 to the apex of the flagellum. 



Mandibles gibbous above, the upper jaw with the terminal fang 

 rather long, curved downwards at the apex, which is remote from 

 the base of the flagellum. First tooth strong, closely followed by a 

 second equally strong tooth, the basal part of which is prolonged 

 posteriorly in the form of a long low ridge ; this is followed by the 

 small outer teeth of the double series ; the first tooth of the inner 

 series long and slender (inner series not drawn in fig. 13). Hind 

 tooth of lower jaw large and strong, preceded by a smaller tooth ; 

 immediately in front of the latter is a long low keel confluent with 

 the base of the smaller tooth ; on the median side of this tooth and 

 keel is a second keel, running along the inner edge of the upper side
