 " Swarm in desert and semi-desert portions of the country. This animal is 

 by no means nocturnal and all my specimens were obtained in broad day- 

 light. They live in little colonies and are particularly partial to "bands" 

 and railway cuttings ; when disturbed the little fellows scamper away into 

 their burrows, but if you keep still, first one head pops out and then another 

 till one bolder than the rest sits up to get a better view, or stands on his 

 hind legs, when he considers all safe he ventures out to be shortly followed 

 by the rest of his brethren, i nearly always found these colonies in the 

 vicinity of those milky plants {Calotropis (jujantea ox procera), the gerbils 

 feed on the flowers and spend much of their time in carrying the leaves 

 away into their burrows." — S. H. P.

" 1 obtained two specimens at Sukkur and one at Gambat. These 

 animals will only be found where the sand is very fine and soft such as in 

 some of the canal beds." — S. H. P.

The type locality of hactrianus is Kandahar, while gerhillinus and theo- 

 baldi were described from the Salt Range. The descriptions of all three 

 are very meagre but there are some topotypes of hactrianus from Kandahar 

 in the National Collection with which the present series agree very fairly. 

 In my Report on Kumaon I spoke of three distinct types of Indian House 

 mice but further material seems to show that there are really only two, viz., 

 the brown bellied {dubius, manei) found in the plains and the white bellied 

 {homourus, hactrianus, &c.) from the Himalayas and N. W, Frontier. When 

 representative topotypes from the Salt llange are available the whole group 

 will no doubt repay a detailed examination.
