XLIX. — New Gtnera and Species of Mammals from the 

 Miocene Deposits of Baluchistan. — Preliminary Notice. 

 By C. FoiiSTEK-CoOPER, M.A., SuperiiitenJeiit, University 

 Museum of Zoology, Cambridge. 



The following specimens were obtained from the Dera Bugti 

 province of Baluclii.stan ; tlie types aful other specimens will 

 be placed, together with the rest of the collection, in the 

 British Museum of Natural History, as soou as the whole 

 coUectiou is catalogued. 



Parabrachrjodus ohtusus, gen. nov. 



In a previousissueof this Journal (vol.xii., December 1913, 

 p. 520) I described a third lower molar as that of a new 

 sptcies doubtfully rel'errt-d to the genus Brachyodus. Some 

 tiagments of maxillae seem to agree with this })articular tooth 

 as regards size and general characteristics, and, as they show 

 a pecidiarity which distinguishes thetn from the genus 

 Brachyodus, a new genus is here created for them. 



Tlie type-specimen of the genus is a left maxilla showing 

 the toiirtli premolar and the lull series of three molars (fig. 1). 

 Like the louer molar (fig. 2) already described [loc. cit.), the 

 itetli are brach}odont and bunodont, with a moderately well- 

 niarktd cingulum, and are not easily to be distinguished 

 from those of B. giganteus, the third upper molar being 

 extremely like the cast of the type third molar of the latter 

 species. The fourth premolar, however, shows a distinct 

 difference, in'that the upper cusp is practically aborted and 

 shows as a very thin ridge lying justin.--ide the well-developed 

 inner cingulum. A side-view (hg. 1 A) is here given, showing 

 the difference between the outer cu.sp, which is normal in 

 size and son)ewbat worn, and the inner cusp, which, though 

 quite untouched by wear, is very small. 



That the condition is not an individual variation is shown
