2fi0 PROCEEDINGS OF THE ACADEMY OP 



Prof. E. 0. TTovey, from the cabinet of Wal)asli College, Craw- 

 fordsville, Indiana. They were part of a collection obtained by 

 Dr. Lorenzo G. Yates from a quarternary deposit of California. 

 One of the specimens is the riglit ramus of tlie lower jaw of a 

 wolf, probably of the Canis indianensis, previously indicated from 

 a si)ecimen found on the banks of the Ohio, Indiana. 



A second specimen consists of the fore part of a maxillary bone, 

 with the second prenular, and the canine alveolus, of a tiger as 

 large as tlie largest living Bengal tiger. It probably indicates a 

 species different from those previously noticed, and might be 

 named Felis imperialis. 



Several specimens consist of upper molar teeth, which ar esup- 

 posed to pertain to Bison latifrons. 



The remaining and most interesting specimens consist of an 

 upper molar and a complete lower molar series of a lama as large 

 as the existing camel. Remains of a still larger species fnun 

 California have been previously indicated under tiie name of Au- 

 chenia californica. The present specimens were referred to a 

 species with the name Auchenia hesterxa. Prof. Owen has de- 

 scribed some remains of an equally large lama from Mexico, which 

 he refers to an allied genus with the name of Palauchenia magna, 

 and which perhaps may be the same as the Auchenia hesterna. 

 An inspection of Prof. Owen's figures of a series of molar teeth 

 leads to the suspicion that he has inadvertently mistaken the 

 upper series for the lower ones, and has thus been led to refer 

 them to a genus different from Auchenia.

Fungus Farasife on a House Prof. Leidy exhibited a mouse 

 witli several whitish masses adherent to the ears, side of tlie face, 

 and nose. The mouse had been caught in the children's dei)art- 

 ment of Blockley Hospital, and was submitted to his exami- 

 nation by one of the attending physicians, Dr. James B. Walker, 

 who had informed him that he had observed a number of mice in 

 the same condition. Dr. Walker had previously' informed him of 

 the curious affection of the mice, and it was at his suggestion that 

 the present specimen was caught for examination. The white 

 matter examined beneath the microscope proved to be composed
