2'! 4 On Mammals from Ceiitral Cordova. 



The species is a most distinct one, its skull being barely 

 half the length of that of the larger form ; its coloration (as 

 may be seen by Burmeister's figure) is widely different, 

 owing to the absence of the contrasted markings on the rumj), 

 while the claws, as pointed out in Weyenburgh's excellent 

 description of his J), centralis, are much narrower and more 

 compressed. The skull is remarkably like that of a half, 

 grown I). vwgellanicuSj but may be readily distinguished by 

 its more deeply notched palate, which is cut out to the level 

 of m^ instead of 7/i\ 



By the kindness of Dr. Berg, of the Buenos Ayres 

 Museum, the original discoverer of the species, the British 

 Museum has been enabled to acquire by exchange one of the 

 co-types. ^Ir. Simons's specimens are not precisely similar 

 in colour to this, but the difference is probably due to its 

 fading. ]n any case the Cruz del Eje specimens, should 

 there be any local variation in the species, will represent 

 Weyenburgh's JD. centralis, described as from Cordova, very 

 shortly after Burmeister's description was published. 



12. Kerodun loliviensis, Waterh. 



S ? . 23rd and 27th November, 1901. 

 These specimens presumably represent Burmeister's Caoia 

 leucoblephara. 



13. Dasypus vellerosus pannosus *, subsp. n. 



3 cr,3 ?. 



Similar to the true veUerosus in all essential respects, but 

 far less thickly haired. Although there are a certain number 

 of long hairs {l\-2 inches) scattered along the sides, the 

 greater part of the fine hairs which spring from the hinder 

 ends of the scales are quite short, about half an inch long, so 

 that there is no general long hairy coat hiding the scales, as 

 is the case in true vellerosus. 



Of vellerosus the Museum contains, besides the type from 

 Santa Cruz de la Sierra {Bridyes), three examjjles from 

 Tucuman {Dinelli) representing both seasons of the year; 

 and these, though varying somewhat in their hairiness, are 

 all consj)icuously more thickly clad than any of the six 

 specimens from Cruz del Eje, where, owing to the different, 

 more desert, character of the country, a different subspecies is 

 likely enough to exist. 



In neither skull nor scaling can I perceive any constant 



* Eagged, half-duthed.
