THE HISTORY OF THE MO AS. 



593 



II. 



Captain Hutton prefaces his new memoir' with an excellent 

 resume of the early history of the discovery of their remains. This 

 is followed by a systematic account of the various genera and species ; 

 and then we find the interesting discussion as to the origin and 

 extirpation of the Moas already given above. 



The author divides the Moas into seven genera, viz. : DinorniSj 

 Palaptevyx, Anomalopteryx, Csla, Mesoptevyx, Syornis, and Enryapteryx ; 



Skeleton oi Pachyontis elephantopus (a) and limb of Dinornii viaximns (b). 



the first including the largest, and the fourth the smallest. This 

 classification differs considerably from the arrangement noticed on 

 page 267 of our June issue, although the difference is really less than 

 at first sight appears to be the case. Putting aside the genus 

 Megalapteryx, which Captain Hutton does not appear to regard as a 

 Moa at all — although we have no doubt that it is — the forms 

 included by our author under the second, third, fourth, and fifth genera 

 are comprised in the British Museum Catalogue under the head of
