Llama Remains, Colorado and Kansas. — ( vagvn>. 259 



Some cameloid remains obtained by Mr. E. I>. Smith and the 

 writer, from loess-marked volcanic ash-beds southwest of Meade 

 Centre, Kansas, arc also apparently referable to Auchenia hut r- 

 fanensis. Most of these, including a second or third lower molar, 

 vertebral and femoral epiphyses, etc., pertain to a young animal, 

 hut there is a proximal half of a first phalanx which, placed side 

 by side with the lirst phalanx of the type of Auchenia huer/an- 

 ensis, tallies with it perfectly in size and proportions. 



A canine with gently curved, conical, and bicarinate crown, 

 found with this phalanx, and which, therefore, may belong to the 

 same species, or even individual, has the enamel thick and smooth 

 on the outer. longitudinally grooved or striated on the inner face 

 The axis of its crown makes nearly a right angle with that of its 

 root, indicating a long post-canine diastema. The two strongly 

 compressed and elevated earime are formed largely (their crests 

 entirely) of the thick enamel-layer of the outer face, and are in- 

 wardly recurved. 



The length of the rectified canine, as preserved, is about two 

 inches — to w hich perhaps a fourth of an inch should be added for 

 the tip. which is broken off. The length of the root is 1.1 inch. 

 Thi' transverse diameter at hase of crown is .4 inch: the antero- 

 posterior diameter at same, about .">..">. The hight of the poste- 

 rior carina at base of crown is about 1 inch, that of the (broken) 

 anterior carina being apparently a little greater. 



The capacious shovel-shaped crown of a lower incisor found 

 with the preceding, and marked with a semicircular depressed 

 area on the distal half of its upper face, may or may not belong 

 to this or another Auchenia. It is a first or "pincer, " canine, and 

 it> maximum or anterior width is. 7.") inch. The rather thick 

 enamel of the front or lower face of this tooth is marked with 

 tine undulating stria'form grooves as in the incisors of the ox. 



A cameloid metapodium from "old river gravel" at Denver, 

 Colorado, and two first phalanges from the ••Denver loess," col- 

 lected by Prof. Geo. L. Cannon, indicate animals somew hat larger 

 and stouter than those indicated by any of the remains above 

 noticed, hut which, as their teeth are unknown, cannot yet he de- 

 termined. 



The metapodium is 14.11! inches in length and. distally, 3. 8 

 inches in breadth, the articular extremities, as well as the shaft, 

 being stouter, in relation to the metapodium of Auchenia Inter-
