^g^'l Chapman, Cainozoic Shark in Victoria. 143 



genera (not species) like Scapanorhynchus (now discovered, 

 however, in Japanese seas in deep water) and Aster acanthus, 

 which are typically Cretaceous elsewhere. On overwhelming 

 molluscan and other evidence the Patagonian series resembles 

 parts of the Oamaru system in New Zealand, and in the main 

 comparable with our Victorian Janjukian.

Holotype. — ^Tooth of slender habit. Root 

 shghtly arched and moderately stout. Crown 

 acutely triangular, flattened on the outer face 

 near the junction with the root, and other- 

 wise depressed convex ; inner face roundly 

 convex ; edge view showing a wide recurva- 

 tion of the lateral line, as in Odontaspis.

Ponds, Vict. ; nat. Measurements. — ^Total length from base 



size. to apex, 20.25 rnm. Extreme width at base 



of root, 12 mm. ; thickness, 4.5 mm. Width of crown at 



junction with root, 7.25 mm. ; thickness, 3.75 mm. Length 



of lateral denticle, 3.75 mm. 



Occurrence. — ^Waurn Ponds quarry, near Geelong. Cainozoic 

 (Janjukian) age. This specimen was found by Mr. J. F. Mulder, 

 to whom the credit is due of discovering many interesting and 

 rare fossils in the Geelong area. 



Carcharoides totuserratus, Ameghino. 

 This form is represented by several specimens from the Waurn 

 Ponds quarries, and they will be described in detail in a sub- 

 sequent paper. 



Black Fox Farming ix Canada. — ^Ten to fifteen years ago 

 Black Fox skins could be bought at about ^ly ; now from £75 to 

 £250 can be obtained. This great advance in the price, caused 

 by the hmitation of the original hunting and trapping grounds 

 by the spread of habitations, has resulted in the estabhshment 

 of numerous ranches or fox farms in Prince Edward Island, 

 New Brunswick, and other parts of Eastern Canada. A large 

 amount of money has been sunk in the industry, as may be 

 seen from the fact that good specimens for breeding purposes 

 fetch £1,000 each, while the progeny of one female has in 

 seven years realized ;f 10,000, and recently six pairs of live black 

 foxes passed to Russian purchasers at £20,000. The success of 

 fox farming has caused attention to be turned to the breeding 

 of other fur-skin animals, such as Skunk, Ermine. Marten, 

 Otter, and Mink. — P. Fairbank, in Country -Side, October, 1912.
