296 RATIT^. 



21753 a. A considcrablj' larger fourth dorsal vertebra ; from the 

 same locality. Probably associated with No. 21753. 



Mantell Collection. 



21753 b. An associated fourth and fifth dorsal vertebra3 ; from the 

 same locality as the preceding, with which the fourth 

 dorsal agrees in character. Mantell Collection. 



32076. Three imperfect dorsal vertebras, apparently the third, fourth, 

 and fifth, with their centra completely anchylosed together; 

 from Te Rangatapu. Prom the abnormal shortness of the 

 centra it is probable that the anchylosis is due to mal- 

 formation. The vertebrae agree nearly in size with the 

 preceding. Walter Mantell Collection. 



21749 g. The fifth dorsal vertebra ; from Te Eangatapu. This 

 specimen is not larger than the corresponding vertebra of 

 A. parva, but has shorter transverse processes, and a deep 

 pit on the neural platform behind each prezygapophysis. 



Mantell Collection, 



21749 h. A larger fifth dorsal ; from the same locality. The cen- 

 trum is relatively shorter and wider, and the transverse 

 processes are more inclined upwards. Mantell Collection. 



21749 i. A still larger imperfect fifth dorsal ; from the same 



locality. Mantell Collection. 



32069. The fifth dorsal vertebra of one of the medium-sized species 

 of the family ; probably from Te Rangatapu. 



Walter Mantell Collection. 



32160. The fifth dorsal vertebra of a larger species; from Waiko- 

 uaitu, South Island. The left transverse process is 

 wanting. Walter Mantell Collecti&n. 



21725 c. A small dorsal vertebra presenting characters intermediate 

 between those of typical examjjlcs of fifth and sixth dor- 

 sals ; from Te llaugatapu. Mantell Collection. 



32066 h. A slightly larger vertebra of similar type ; from the same 

 locality. Walter Mantell Collection. 



32133. A very similar imperfect vertebra ; from the same locality. 



Walter Mantell Collection, 



32066 C. A slightly imperfect sixth dorsal vertebra; from Te 

 Eangatapu. Nearly of the size of A. parva.
