1906.] MAMMALS FROM BECHUANALAND. HI 



an instance of its occurrence seems worthy of record. Dr. Forsyth 

 Major has recorded instances in other orders in a paper published 

 in the ' Proceedings ' *. 



" Native name ' Koti.' 



" These mice were caught in the bush not far from the river. 

 The animal has a pouch on each side of its face, which it fills with 

 seeds, giving it a very curious appearance." — H. B. W. 



22. Arvicanthis pumilio gbiqu^ Wrought. 



c? . W. 7, 9 ; D. 10, 11. $ . W. 10, 11, 104 ; D. 9. Kuruman. 



Until the appearance of Mr. R. 0. Wroughton's very carefully 

 thought-out paper on the "Various Forms of Arvicanthis 

 pumilio " t, I had considered this series to be identical with 

 A. p. hechuance Thos. It is noAv, however, abundantly clear that 

 it should be considered a distinct local race. 



"These mice are not uncommon on the bush-veldt near the 

 river. They come out a good deal by day." — K. B. W. 



23. Georychus lugardi de Wint. 



c? . W. 102, 10.3. ? . W. 95. Molopo, west of Morokwen. 



This series exhibits a tendency to prolong the white blaze on 

 the forehead into a dorsal stripe, a characteristic that is wanting 

 in the type of the sjDecies. Specimen no. 102 (B.M. no. 4.10.1.89) 

 is remarkable for the abnormal development of the ascending 

 premaxillary processes, which meet in the middle line behind the 

 nasals, thus entirely isolating the latter bones from the frontals. 



This condition is, so far as I am aware, unique in the British 

 Museum's very large collection of Georychi. 



" These specimens were caught in the dry bed of the Molopo 

 River and the sandy veldt some distance from it. The natives 

 told me that all the Moles on the river-banks were like these." — 

 E. B. W. 



24. Georychus sp. 



5. D. 21. Kuruman. 

 $. W. 71. Morokwen. 



25. Pbocavia capensis Pall. 



One specimen, imnumbered. Kuruman.
