There are two mental foramina in the specimen, one below the third, 

 the other below the first premolar. The crown of the canine is contracted 

 and cnrved; slightly flattened on the inner side.

Helices are extremely abundant in the matrix, with a few other mol- 

 luscs. They have been identified for me by my friend, Geo. W. Tryon, 

 as follows: — 

 Mesodon dentiferus, Biuney. 

 " major, Binn. 

 " albolabris. Say. 

 Xolotrema appressa. Say. 

 Xolotrema palliata, Say. 

 Stenotrema sp. near hirsuta. 

 Anculotus carinatus. 



Associated were numerous vertebrae of Ci'otalus and perhaps Tropido- 

 notus, fragments of Trionyx ^and Cistudo, and- Menopoma. Also frag- 

 ments of a Unio, and the ungueal phalange of a bird of prey. There 

 were no human remains of any kind discovered in the breccia. 



A collection of fossils of similar character to the preceding, was ob- 

 tained by Dr. Samuel Harrison of Easton, Talbot co., Maryland, and is 

 preserved in the cabinet of the Baltimore Academy of Natural Sciences. 

 The specimens were exhumed in the course of excavating for marl on the 

 farm of Lambert Kirby, in Oxford Neck, Talbot County. They consist 

 of a considerable number of fragments of the Elephas a m e r i c a n u s, 

 Leidy, with two molars, the tusks, and maxillary, premaxillary and parts 

 of frontal bones. Fragments including parts of antlers, not distinguish- 

 able from Cervus canadensis, and Cariacus virginianus; the 

 humerus of a Chelydranot distinguishable from that of C. serpentina 

 and of the largest size the species is known to attain ; and a portion of 

 the margin with posterior costal and vertebral bone of Cistudo eurypygia 

 Cope, sp. nov. A molar tooth accompanied the above, which resembles 

 that of the half grown Elephas p r i m i g e n i u s or E. c o 1 u m b i , but 

 has not the lateral curvature of the latter. 



In the earth on the floors of the caves which abound in the lime-stone 

 region of South Western Virginia, the remains of the existing Mammalia 

 of the country may always be found. I have procured Lynx, Vulpes, 

 Procyon, Cariacus, Didelphys, etc. In one chamber the fresh food, ap- 

 parently of a raccoon, was found, consisting of fresh hazel nuts, wild 

 plum, choke cherry, chicken grapes, acorn, etc. In many, human remains 

 occur, with beads, needles of bone, etc. 



In Erhardt's Cave, Montgomery County, Virginia, the writer found 

 four or five specimens of a new Anophthalmus, the A. pusio of Horn, at a
