33100 a. A slightly smaller and somewhat imperfect axis vertebra, 

 of the same contour as the preceding specimen. 



Walter Mantell Collection. 



33009. An axis vertebra of a shorter type than the preceding 

 specimens, and with a divided neural spine. If the two 

 preceding specimens be referable to A. curta, the present 

 one may well have belonged to A. (?) geranoides. 



Walter Mantell Collection. 



31741. Four specimens of the third cervical vertebra. These are 

 somewhat narrower than the third cervical of A. pa^'va, 

 with a more slender centrum, bearing a thinner haemal 

 spine. 



31741 a. A third cervical vertebra of a shorter type than the pre- 

 ceding, and thereby resembling the axis No. 32009, with 

 which it is probably specifically identical. 



31741 b. The fourth cervical vertebra. 



31741 c. A shorter fourth cervical vertebra. Probably specifically 

 identical with No. 21741 a, 



31741 d. The fifth cervical vertebra. 



31755. A similar specimen. 



31755 a. A rather shorter fifth cervical vertebra. 



31753. Two specimens of the sixth cervical vertebra. 



31733. An imperfect sixth cervical vertebra. 



31740. The imperfect seventh cervical vertebra. 



31755 b. An imperfect seventh cervical vertebra. 



31740 a. A smaller seventh cervical vertebra. 



31740 b. Two specimens of the eighth cervical vertebra. 



31753 a. An imperfect ninth cervical vertebra. This vertebra can 

 be readily distinguished from the eighth by the contour of 

 the channel of the lateral arch. 



31740 c. A smaller imperfocr, ninth cervical vertebra. 



31746. Two specimens of the twelfth (?) cervical vertebra. 



31737. A nearly similar vertebra.
