descending from the enamelled surface above the basal 
dentine. The fossil. fragment shows only the upper part 
of this ridge, where it subsides into the general surface, and 
even here it is only to be traced by a faint groove on its 
anterior side. 
Viewed in front, the tusk has an outward curve, as in the 
Babirussa. The inner surface is broad, a little convex fore 
and aft, and obliquely curved longitudinally. There areno 
signs of ridges at the lowerend. Their absence, both from 
the outer and inner sides, indicates that the fossil is the 
subterminal part of the tusk. If so, the abrasion of the 
hinder surface did not extend so low upon the tusk as in 
Dicotyles, in other words, the upper and lower canines did 
not antagonise so completely. 
Assuming that these fossils will be found to typify a new 
genus of the extinct Suillines, I venture to propose for it the 
name Prochcerus, with the specific limitation ce/er, both 
terms in allusion to its occupation of the country before 
the true pigs. The comparative frequency of its teeth 
shows that it was not altogether a rare member of the 
post-pliocene fauna.* 
EXHIBITS. 
The President exhibited on behalf of the Colonial Botanist 
—Fruit of Eleocarpus bancrofti, Baz/. and F. v. M., a tree 
productive of excellent timber and an edible fruit; the 
ribbed fruit of Ficus pleurocarpa, /. v. W%., probably a 
valuable timber tree ; pods, &c., of Cassia brewsteri, F. v. MZ,, 
medicinal; fruit of Tarrietia trifoliolata, Baz/., a large 
timber tree; bark of Daphnandra aromatica, Aaz/., a new 
spice bark ; foliage of Grevillea pinnatifida, Baz/., extremely 
ornamental—the wood, one of the most beautiful of Queens- 
land woods; screw-like pod of Archidendron Vaillantii, 
f.v. M.,atimber tree. Most of the trees of which these 
illustrations were exhibited were stated to be growing at 
the Johnstone River. 
* The ‘‘ quinque-tuberculate tooth of bunodont type”’ was obtained at 
Sharrow, and the remaining fossils at other localities on the Darling 
Downs.—Ep.
