On the Skeleton of the Apteryx. 

 By Thomas Allis, E.L.S. 



[Bead December 3, 1872.] 



There were exhibited two photographs of the skeleton of an 

 Apteryx, which he had prepared and mounted himself; and Mr. 

 Allis pointed out that it diflfered from the one figured by Pro- 

 fessor Owen (in the second volume of the 'Transactions of the 

 Zoological Society ') in the absence of a nail at the end of the 

 wing, in the greater breadth of the ribs, in the absence of foramina 

 in the sternum and scapulo-coracoid, and in the more complete 

 anchylosis of the sacro-caudal vertebrae — differences most of whicii 

 might be attributed to the more mature condition of the specimen.
