The above species is named in honor of the late Mr. Oscar 

 Harger, whose work in connection with the early Yale Expe- 

 ditions is so well and favorably known. The locality of the 

 type and cotype is Henry's Fork, Bridger Basin, Wyoming, and 

 the specimens were found by Messrs. Oscar Harger and F. S. 

 Weeks of the Expedition of 1873. Two other fragmentary 

 examples are from Point Gulch, near Henry's Fork. 



Neovulpavus washakius, gen. et sp. nov. 



Vulpavus palustris Wortman and Matthew, Bull. Amer. Mus. Nat. Hist., June, 

 1899, p. 118. 



It is now evident that the species published by Dr. Matthew 

 and myself, under the name Vulpavus palustris, is distinct 

 from the typical representative of the genus above described. 

 The difference consists in the loss of the third superior molar, 

 and as this is in direct line of progressive modification towards 

 Cynodictis and represents an intermediate step between Pro- 

 cynodictis and Vulpavus, it may be regarded as a distinct genus, 

 for which the above name is proposed. With the exception of 

 the loss of the third molar, it agrees closely with Vulpavus. 

 The type is from the Washakie Basin, and is preserved in the 

 American Museum Collection ; its catalogue number is 2305. 

 It was fully described and figured in the Bulletin of the Ameri- 

 can Museum, 1899, p. 118.

Typically small or medium sized imperfectly known Canids, 

 with dentition I ? , C T , Pm r , M3, having an inferior sectorial with 

 a disproportionally large trigon and small, low, cutting, or slightly 

 basin-shaped heel ; cusps of succeeding molars, low and blunt. 

 First superior molar, in type species, with anterior border much 

 elongated, the two external cusps unequal in size, and the inter- 

 nal cusp without posterior transverse lunate ridge. Jaw, either 

 short and deep, or elongated and shallow. Premolars unreduced. 



Uintacyon edax Leidy. 



This species was established by Leidy upon an imperfect 

 and anomalous lower jaw, in which there are five premolars 

 instead of four. The sectorial is damaged in such a way as 

 not to display satisfactorily the characters of the heel, but it 

 seems highly probable that it was made up of a cutting ridge,
