39361. The conjoint cervical vertebrae in a slightly imperfect con- 

 dition ; from the bed of the Thames at Wapping. This 

 specimen differs from the corresponding vertebral mass of

 the same part in the present species given by Van Bene- 

 den and Gervais in their ' Osteographie des Cetaces,' pi. vii.

 of the condylar cups of the atlas, the narrow interval 

 between them, the small nutrient foramen, and the nearly 

 horizontal direction of the inferior border of the lateral 

 arch in the second and third vertebrae. Par-chased, 1801,
