the antero-extornal crest of the shaft is less sharp and does uot 

 extend so low down : the trochleae arc longer, the second being less 

 extended laterally, and the fourth shorter in proportion to the third. 

 The femur has a larger surface for the attachment of the ligamentum 

 teres ; and the anterior intercondylar groove of the tibio-tarsus is 

 somewhat wider. 



The cervical vertebrse differ from those of Vidtur by the greater 

 lateral constriction of the inferior surface of the centrum ; this 

 surface in some of the hinder cervicals being convex, with a sudden 

 descent to the very deep pit behind the anterior articular surface, 

 and with either one median pneumatic foramen or a pair of foramina 

 below the root of the lower transverse process. The anterior arti- 

 cular faces of the centrum are also wider, with sharper edges. 



Gyps melitensis, Lydekkeri. 



The largest known species referable to any existing genus in the 

 suborder, its size being about one fifth greater than in the existing 

 Vultur monaclms. The later cervical vertebrte have the anterior 

 tubercle on the inferior surface of the centrum more developed than 

 in the living Gyps fulvus. 



Hah. Malta. 



The following specimem, which are the types, were obtained from the 

 Pleistocene deposits of Zebhug Gave, and luere presented by 

 Admiral Spratt, O.B., 1874. 



49355. The imperfect head of the right femur. This specimen 

 shows the large surface for the attachment of the liga- 

 mentum teres characteristic of the genus. The diameter 

 is 0,018, against 0,015 in V. monachus. This specimen 

 is noticed in the paper cited below. 



49355 a. The distal extremity of the right femur. This specimen, 

 {Fig.) which is probably the distal part of the bone to which the 

 preceding belonged, is figured by the writer in the ' Proc. 

 Zool. Soc' 1890, pi. XXV. figs. 4, 4 a. Its contour agrees 

 in all respects with that of the corresponding bone of 

 v. monachus, the respective transverse diameters in the 

 two bones being 0,044 and 0,037.
