Iksides the dilTerences noti d above, stronj^ly grooved upper 

 incisors separate this species ivowx/tiUax, Thos. & Schw. 



I have much pleasure in naming this fine well-marked 

 species after Mr. (3. D. lludd, to whose generosity we owe 

 the fine collections made by Mr. Grant in S. Africa, which 

 alone have made possible any useful investigation of this 

 and other S. -African groups. 



(2) Tutera draco, sp. n. 



4. 9. 1. .'39-42. Wakkerstroom, Transvaal. (Rudd Explora- 

 tion.) Alt. 6000'. 



A form very near Brantsi, but consistently larger all 

 round. The dark upperside of the tail dies out distally and 

 leaves a white tip, but not to the same extent as in Brantsi. 

 There is a much greater admixture of black on the back and 

 the white underside is strongly tinged with rufous on the 

 median line, across tlie chest, and on the lower surface of the 

 tail ; in this last it resembles RuddL The normal measure- 

 ments are : — 



Head and body 160 mm. ; tail 175 ; hind foot 36; ear 22. 



Skull : greatest length 42 ; basilar length 34; zygomatic 

 breadth 23 ; length of upper molar series 6*5 ; length of 

 buUce 11. 



Its greater size and the rufous tinge of the under surface 

 distinguish this species from Brantsi, while its shorter 

 liind foot and tail differentiate it from Ruddi, its near 

 neighbour on the other side. 



I have named it draco from its habitat on the Drakensberg.
