566 Selected Specimens of [Oct. 



The accompanying plates contain drawings £th the natural size 

 of a few of the Sub-Himalayan fossils in the Dadupur collection, 

 viz. selected specimens of the remains of the horse, the hog, rumi- 

 nants and carnivora. 



To save a lengthened description, and the use of technical terms, 

 with which I am not familiar, as well as for the sake of ready com- 

 parison, I have accompanied my drawings of several fossils by those 

 of the corresponding bones of their existing analogues. 



I may here remark, that the greater part of the fossil, as well as of 

 the recent bone?, were sketched with the assistance of the Camera 

 Lucida, and allowing for the slight errors incidental to that instru- 

 ment, I believe them to be correct " plans and elevations," if I may 

 use the term, of what they are intended to represent. 

 The fossil horse— PL XLV.figs. 1 to 19. 



The remains of this animal, now in our collection, are amongst the 

 latest of our acquisitions ; and as many of them present a marked 

 difference from the fossil horse, described by Cuvier, which appears 

 not to have been distinguishable from the existing species, I have 

 been induced to figure nearly all our recognized bones of this 

 genus. 



Fig. 1 represents a fragment of a left molar of the upper jaw ; 

 though a mutilated specimen, it clearly shews the same complicated 

 flexures of the crown, compared with fig. 2, which is the fourth left 

 upper molar of the existing horse. Fig. 3, shews the fourth and fifth 

 molars of the left lower jaw of the fossil, and fig. 4, the same teeth of 



the volume now in the press, along with the highly interesting description of 

 the Sivatherium, by Messrs. Falconer and Cautley. 



The shells of the red marl, alluded to above, are perfectly identical, both 

 in form and state of preservation, with those we received with the collection of 

 Ava fossils from Colonel Burney. No drawing is given of these shells in 

 Professor Buckland's account of the Burmese Mastodon, and he remarks, that 

 V neither the insulated concretions from Ava, nor those adhering to the bones, 

 contain traces of any kind of shells ;" but on noticing the peculiarities of the 

 tertiary strata in the neighbourhood, he says, " among the most remarkable of 

 these strata is a fresh-water deposit of blue and marly clay, containing abun- 

 dantly shells that belong exclusively to a large and thick species of Cyrena." 

 This doubtless coincides with figs. 45, 46, of our plate :— and further, " also a 

 dark-coloured slaty lime-stone, containing shells which Mr. Sowerby has iden- 

 tified with some that occur in our London clay. There is also, from the hills 

 opposite Prome, granular yellow sandy lime-stone, containing fragments of 

 marine shells, and much resembling the calcaire grossier of the environs of 

 Paris." This I presume alludes to the spiral univalve, fig. 44, which I find pre- 

 cisely among Colonel Burney's specimens, and which much resembles the princi- 

 pal shell of the calcaire grossier. — Ed.
