! 2V2^e.— Adult female. B.M. No. 12.7.8.1. Original No. 893. 

 Oollected by Mr. C. A. Crump, 10th Februarj-, 1912, and pre- 

 sented to the National Collection by the Bombaj- Natural Histoiy 

 Society. 



(^ , Mr. Crump obtained six specimens from various places round 

 Pachmarhi. This is no doubt the representative of simcoxi in the 

 altered conditions of hilly country, heavy rainfall, and thick forest 

 found in the Mahadeo Hills. The dark and rich colouring and 

 the absence of the pale grey rump distinguish it at once from 

 simcoxi. 



D. — The Genera leggada and mus. 



. In a recent issue of this Journal (Vol. XXI, p. 772) Wroughton 

 described, on a single specimen, taken by Mr. Crump at Asirgarh 

 in the Nimar District, a new species, Mus ]:>hilliim. A careful 

 revision of the Nimar Collection (No. 4) has resulted in the dis- 

 covery of two more specimens ( 5 180...Chikalda and $ 205...PiIi 

 Sipna Valley^, from an examination of which we are now in a 

 position to record that the mammary formula of i:)hilli'psi is 

 3—2 = 10. 



In the Bellary Collection there is a series of eight specimens, 

 taken by Mr. Shortridge at Vijayanagar, which though closely 

 allied to _pA'iZKj9si represent a distinct species. Before describing 

 this new form, however, we have felt compelled to enquire into the 

 whole question of the status of the two Genera Mus and Leggada. 



Leggada was separated from Mus hj Gray, in 1837 (A.M.N.H. 

 I^ p. 586) when he included in it two species, viz., hooduga and 

 Ijlatythrix. Hitherto hooduga has been accepted as best represent- 

 ing the genus, and the presence of " an additional lunate lobe at 

 the base of the front edge" of the upper anterior molar, cited by 

 Gray, has been regarded as the primary generic character. This 

 position is no longer tenable, for recently a number of species, 

 allied to hooduga, have been discovered in Africa, in many of 

 Y/hich this character is but imperfectlj'' developed, and in some is 

 entirely absent. 



Mr. Thomas has pointed out to us that the name Leggada is 

 based on " leggyade," the Kanarese name of platythrix (teste Elliot, 

 Madr. Journ. L. & Sc. X, p. 215) and that, consequently^, by the 

 rule of tautonomy, 'platythrix, and not hooduga, is the tj^pe species 

 of the Genus Leggada, and has advised us to adopt the presence or 

 absence of frontal ridges* on the skull as the primary generic 

 character, in the place of the one mentioned above. 



The adoption of this position necessitates a complete redistri- 

 bution of the known species between the two Genera Mus and 



* (Note. — These are well shown in the text block published on page 773 of a 

 recent issue (Vol. xxi, 1912, of this Journal.)
