DINORNITHrD.E. 347 



A. 202 b. A smaller series of tracheal rings of the same general 

 type as the preceding, but smoother ; locality unknown. 



JVo history . 



A. 203. A series of tracheal rings generically distinct from the 

 {Fij.) preceding ; from Ruamoa. Described and figured by 

 Owen in the ' Trans. Zool. See' vol. vii. p. 387, pi. xlvii. 

 figs. 1-9, and also in his 'Extinct Birds of New Zealand,' 

 p. 331, pi. xciii. figs. 1-9, where they are referred to 

 Emeus (Dinornis) crassus. These specimens consist of 

 thin, hoop-like rings, and are thus very difierent from the 

 preceding specimens, which are tube-like. From their 

 resemblance to the smaller rings of Anomalopteryx parva 

 (p. 280), it is probable that they belong to one of the 

 larger species of Emeus or Anomalojiteryx. The specimen 

 represented in fig. 8 of the plates appears to be a portion 

 of the larynx. Walter Mantell Collection. 



A. 203 a. Four similar tracheal rings, in matrix ; from the same 



{Fig.) locality. Described and figured by Owen in the ' Trans. 



Zool. Soc' vol. vii. p. 389, pi. xlvii. fig. 12, and in the 



' Extinct Birds of New Zealand,' p. 331, pi. xciii. fig. 12, 



as Dinornis rheides. Walter 3Iantell Collection. 



A. 204 a. An associated series of similar tracheal rings, in matrix ; 

 from the same locality. Walter Mantell Collection. 



A. 205. A larger series of similar tracheal rings ; from the same 

 locality. Walter Mantell Collection. 



A. 205 a. A series of specimens, some of which are similar to the 

 preceding, while others are smaller ; from the same locality. 

 The smaller specimens are only slightly larger than the 

 tracheal rings oi Anomalopteryx joarva. 



Walter Mantell Collection. 



A. 205 b, c, d, e, f. Other scries of similar specimens ; from the 

 same locality. Walter Mantell Collection. 



A. 205 g. A small series of similar specimens ; locality unknown. 

 These specimens differ from the preceding by being of a 

 buff, instead of a nearly black colour. No history. 



A. 206. A small series of specimens of the same general type as 

 the preceding ; probably from Glenmark Swamp. These 

 specimens are of large size. No histoi-y.
