Gexertcallt Undetermined Remains of Dinomithidm. 



a. Rings of the Trachea. 



A. 204. A large scries of tracheal rings of one of the larger forms ; 

 apparently (judging from their mineralogical condition) 

 from Glenmark Swamp, Canterbury, South Island. These 

 specimens form comparatively long cylinders, which are 

 of a less rugged nature than the following ones. If the 

 latter be referable to Pachyornis, the present type may 

 well belong to Dinomis maximus. No history. 



32246 a. Eight specimens of tracheal rings of one of the larger 

 {Fig.) forms; from lluamoa, near Oamaru Point, South Island. 

 These specimens, several of which consist of two rings 

 anchylosed together, are described and figured by Owen 

 in the ' Trans. Zool. Soc' vol. vii. p. 390, pi. xlvii. figs. 

 24-32, and 'Extinct Birds of New Zealand,' p, 330, 

 pi. xciii. figs. 24-31, where they arc provisionally assigned 

 to Binornis robustus. The absence of remains of Dinomis 

 from the Ruamoa deposits, and the abundance of those of 

 Pachyornis, renders it more likely that the present massive 

 type of tracheal rings is referable to that genus. 



Walter Mantell Collection. Purchased, about 1855. 



32246 b. Seven specimens of tracheal rings of the same type as the 

 {Fig.) preceding; from the same locality. Described and figured 

 by Owen in the ' Trans. Zool. Soc' vol. vii. p. 390, pi. xlvii. 

 figs. 17, 19, 20, and in the ' Extinct Birds of JSTew Zea- 

 land,' p. 331, pi. xciii. figs. 17, 19, 20, where they are 

 provisionally referred to Dinomis ingens.

32246. An extensive series of similar tracheal rings ; from the same 

 locality. Walter Mantell Collection. 



A. 202. Five tracheal rings, of the same type as the preceding, but 

 {Fig.) of rather smaller size ; from Ruamoa. Described and 

 figured by Owen in the ' Trans. Zool. Soc' vol. vii. p. 390, 

 pi. xlvii. figs. 13-16, 18, and also in the ' Extinct Birds 

 of New Zealand,' p. 330, pi. xciii. figs. 13-16, 18, where 

 they are referred to Pachyornis {Dinomis) elephantopus.
