Squalodon, from Dinan, Brittany,* but as these generic names and also Zenglodon, appear 

 each to have been applied to several very distinct animals, I deem it advisable to retain the 

 name Kekenodon for the New Zealand fossil. 



On Plate XVIII., I figure the best preserved portions of this interesting fossil, of the 

 natural size. It will be seen that the molar teeth have not the widely divergent and 

 separately implanted fangs of the Zenglodon of Owen, while the enormous development of 

 the fangs in proportion to the crowns of the teeth, at once distinguish them from the 

 genus Plwcodon of Agassiz, established on the Maltese fossil described by Scilla, in 1652, 

 but which partly on account of this short-fanged character of the teeth, was referred by 

 Owen to Hippopotamus.! 



EXPLANATION OF PLATE XVm. 



Fig. 1. Canine tooth (?) lower of right side, showing the roughly fluted inner surface 

 of the conical apex, bounded by the cutting ridges, and the large bulbous 

 solid fang. V is a section of the crown of the tooth, showing the enamel 

 coating the dentine. 1" is a longitudinal, and V" is a transverse section of 

 a segment of the fang showing the massive cement layer coating the solid 

 ivory of the tooth. 



Fig. 2. The upper canine (?) of the left side, showing the comparatively smooth exterior 

 surface of the crown. 



Fig. 3. First (?) molar, exterior aspect, showing at the extremity of the fang a trilobate 

 character, illustrated by the transverse section. 



Fig. 4. Second (?) molar, exterior aspect, and 4' a lateral view of the same. 



Fig. 5. Third (?) molar, which has the fangs most widely separated of all the teeth. 



Fig. 6. and 6'. Two views of the fourth (?) molar. 



Fig. 7. and 7'. Two views, interior and posterior, of the fifth (?) molar, showing the 

 strong unequal fangs, and the obliquely triangular crown. 



Fig. 9. Interior aspect of the tympanic Bulla, 9.' exterior surface. 



Fig. 10. Interior or opposing surface of the Periotic.

Some time since, among the sand-hills at the southern end of the isthmus which con- 

 nects Miramar peninsula with the main land, accompanied by Mr. Page, I found a toler- 

 ably complete skeleton of a man, and portions of several others of much slighter build, 

 probably belonging to women, together with a quantity of chert and obsidian flakes, etc. 



Amongst the chert flakes I was struck with the unmistakeable arrow-head-like form 

 of two pieces, that of No. 1, a flint, being most marked; No. 2, a chert, is broken, and 

 may or may not have been a similar weapon. 



I believe there are, both in the Ghristchurch and Auckland Museums, implements 

 supposed to have been used as arrow-heads, but in no case do they possess so decidedly 

 the characteristic features of such implements as in this instance.
