nearly adult animals. Cat. No. 142355, U.S.N.M., is the youngest, 

 the last upper molar is just through the alveolus, and is entirely 

 unworn. Cat. No. 142353, U.wS.N.M., is of about the same age. 

 Cat. No. 142350, U.S.N.]\I., the female, is a little older than the two 

 preceding, as the last upper molar is beginning to show wear. The 

 last upper molar in Cat. No. 142354, U.S.N.M., shows more wear than 

 any of the foregoing, but not so much as the remaining two. Cat. Nos. 

 142352 and 142351, U.S.N.M., which are fully adult boars. The 

 teeth of No. 142351, U.S.N.M., show considerable wear. The lower 

 jaw sent in with this specimen evidently came from another indi- 

 vidual, as it does not fit the skull accurately. However, it is the 

 lower jaw of a male of about the same age, or perhaps a trifle older, 

 and from an animal about the same size.

" Palatal length measured from the most anterior portion of the posterior edge of the lateral halves 

 of the palate, and not from the notch between the two halves of the palate. Tlie latter point seems to 

 be variable and becomes pushed farther backward with advancing age. 



[I did not see a single live pig in Borneo. Judging from the tusks, 

 the Dyaks keep the lower jaws only, some of the boars must be 

 enormous. — W. L. Abbott.]
