A SMALL COLLECTION OF RODENTS FROM SIND. 1001 



These specimens are of course not true rattus and I can find 

 nothing in the Museum Collection with which they exactly agree. 

 Probably in the loose terminology of students of rattus from the 

 plague point of view, alexandrinus would include these specimens. 

 The whole series is extraordinarily constant in coloration. 

 (289 part). Leggada plahjthrix sadhu, sub-sp. n. 

 rf 21. (Presented to the National Collection.) 

 Bennett originally described plakjthrix from specimens collected 

 by Col. Sykes " in Dukhan " and stated its colour to be " fusco- 

 canescens " and again " testaceous brown " with a greater or less 

 admixture of black. The present is a true ' desert ' form, < drab- 

 grey ' darkening in the centre of the back to ' smoke grey. ' 



The skull closely resembles that of a specimen from Ahmed- 

 nagar, which may be taken as typical ; but the bulte are smaller, 

 the palatal foramina shorter, and the brain case shorter and deeper ; 

 the upper incisors are pale and white-tipped. 



Dimensions of the type (measured in the flesh) : head and 

 body 79 ; tail 57 ; hind foot 17 ; ear 12-5. 



Skull :— Greatest length 25; basilar length 21; zygomatic 

 breadth 12 ; nasals 10 ; diastema 7-5 ; anterior palatal foramina 6 ; 

 upper molar series 4-5. 



Hob.— Lower Sind. (Type from Virawah, Thar and Parkar.) 

 Type.— Adult male. B. M. No. 11, 3, 13, 8. Original number 

 21. Collected by Mr. E. Priestley, D. S. P., Thar and Parkar, and 

 presented to the National Collection by the Bombay Natural 

 History Society.

 This interesting animal, owing to its characteristic desert colour- 

 ing superficially, resembles the last so much that at a first glance 

 it might be mistaken for it. Closer examination, however, proves 

 it to be not only specifically but generically distinct. Mr. Thomas 

 is dealing with it in a separate paper. I would suggest that the 

 Society should try and induce Mr. Priestley to obtain more 

 specimens including one or two adult females (with well deve- 

 loped mammae) in alcohol.
