No. 2328. PLEISTOCENE VERTEBRATES IN UNITED STATES— HAY. Ill 



some brown iron oxide. It is pretty certainly a fossil, but was pn^b- 

 ably not found in the loess. 



PLATYGONUS COMPRESSUS? Leidy. 



There is in the collection a fragment of a lower right canine tooth 

 of a peccary (Cat. No. 9001), which is identified provisionally as 

 that named. The fragment is 35 mm. long, 14 mm. from the acute 

 front edge to the slightly concave hinder face, and 11 mm. across 

 this hinder face, the measurements being taken at what was about 

 the middle of the height of the crown. On the outer face there is 

 a median ridge bounded in front and behind by shallow^ grooves.

In the collection made at Alton are two nodules of loess with each 

 a part of the right ramus of the lower jaw and three molars of a 

 large deer. In the better specimen (Cat. No. 9002. PL 5, figs. 5, 6) 

 the first molar is much damaged and the third has lost most of the 

 hinder lobe. The inner faces of the teeth are mostly hidden in the 

 hard nodule. The first molar was close to 15 nmi. in length. The 

 second is 18 mm. long and about 13 mm. wide. The third molar, 

 not including the third lobe, is 18 mm. long; including the third 

 lobe, it w^as about 22 mm. long ; the width, about 13 mm. The crowns 

 are only moderately worn. The other nodule (Cat. No. 9003) pre- 

 sents the same sides of the teeth, the inner faces being more concealed 

 than in the first nodule. The crowns are less w^orn and have a height 

 of about 15 mm. The teeth are apparently larger than in the other 

 specimen, the first and second lobes of the third molar, taken to- 

 gether, measuring 20 mm. ; with the hinder lobe, about 27 mm. At 

 the outer mouth of the median valley of these teeth there is a con- 

 spicuous accessory pillar. The crowns of the lower molars are higher 

 than in Odocoileus. The inner faces of the lobes are flatter than in 

 Odocoileus, and the styles are less cons2:)icuous. 



These teeth are entirely too large to have belonged to any of the 

 existing species of Odocoileus; and they are, relatively to tlie length, 

 much broader. They agree in size so well Avith the upper tooth which 

 forms the type of S. fugitiva, found at Whitesburg, Tennessee, and 

 with the lower tooth found at Cavetown, Maryland, that they are 

 referred to that species. In size they agree well with the lower molar 

 found at Cavetown, Maryland, and referred to S. fugitiva.
