The skull of this specimen is nearly complete (pis. 35, 36). A 

 portion across the middle of the face is missing, and this has carried 

 with it the right premolars. The molars of this side are present, as 

 are the molars and the premolars of the left side. >The first incisor of 

 the right side is missing, the others are present. The lower jaw is 

 present, but lacks the premolars of the left side and two of those of 

 the right side. Attached to the skull was the atlas. Of the anterior 

 limbs both radii are preserved, with little injury. Of the right hind 

 leg there are present the patella, the tibia (lacking about the upper 

 fourth), the astragalus, the calcaneum, the cuboid, and the third 

 metatarsal, except some portions thereof. Of the left hind leg there 

 are present a small part of the distal end of the tibia ; all the bones 

 of the ankle ; the third metatarsal, excepting a part of the shaft ; the 

 proximal halves of the second and fourth metatarsal; and the first 

 and second phalanges of the third digit. The hoof phalange is 

 missing. 



Besides these parts there is a considerable amount of fragments of 

 limb bones, vertebrae, and the like, some of which will receive con- 

 sideration. 



All the bones are thoroughly fossilized. They were imbedded in a 

 layer of sand and small gravel; and these materials were cemented 

 together by calcium carbonate, thus forming a matrix which in places 

 is hard and rather difficult to remove. 



From a report published recently by Dr. Alexander Deussen of the 

 United States Geological Survey, 1 it is learned that the deposits in 

 question belong to the Lissie formation, named from the town above 

 mentioned. This formation occupies a strip which runs across the 

 State of Texas, parallel with the Gulf coast line, and having its 

 southern border about 55 miles at the east from the coast. The strip 

 has a width of about 25 miles wide in its western half. The forma- 

 tion consists mostly of gravels and conglomerates, in some places 

 containing considerable limy materials. In the eastern part of the 

 State there are red clays and ferruginous sands. It is believed that 

 to this formation corresponds the middle of three terraces which are 

 found along many of the large rivers of that State. It is supposed 

 by Deussen that the materials of the Lissie formation were spread 

 out at the mouths of the valleys of the streams which discharged into 

 the sea during some parts of the Pleistocene, probably the early and 

 middle parts. 



The present writer is inclined to believe that the Lissie belongs to 

 the early Pleistocene, corresponding, in part at least, to the Aftonian. 

 From Hardin County was obtained Equus complicatus, associated 

 with the saber-tooth tiger Smilodon fatalis and two extinct species 

 of fresh-water tortoises. The great ground sloth Megatherium has
