of a left humerns apparently referable to this species ; 

 from the Pleistocene cavern-deposits of Gibraltar. The 

 ■whole of the head and the palmar aspect of the bone are ex- 

 posed, the region below the head being comminuted. The 

 form of the head and of the surface for the insertion of the 

 pectoralis major conclusively prove the Accipitrine nature 

 of the specimen. Allowing for its comminuted condition, 

 the specimen agrees in size with the humeri of recent 

 examples of the present species. In the shortness and 

 thickness of the head, the great length and relative position 

 of the inner border of the surface for the pectoralis major, 

 and the slenderness and rounded form of the shaft below 

 the latter surface, the specimen agrees with Halia'etus and 

 differs from the Vultures. No history.

 of the preceding.

 The tibio-tarsus has its distal extremity mi;ch more compressed 

 from back to front than in the Vultures ; while the tarso-metatarsus is 

 elongated, with an almost completely prismatic section in the middle 

 of the shaft, the coiistriction of the shaft is very gradual, and the 

 troehlete are nearly on the same level.
