straight sternal articulation, the inner lip of which is but littlo 

 developed, and large suhclavicular process and perforation. 



The -wing-bones are elongated, the ulna being longer than the 

 humerus. The latter is elongated and curved, with a small proxi- 

 mal and a large distal extremity ; its long delto-pectoral crest 

 forms a regular curve, with the surface for the pectoralis major 

 indicated by a nearly straight line extending from the upper to the 

 lower extremity ; the border of the subtrochanteric fossa is very 

 thick, and nearly the whole of the fossa is occupied by the pneumatic 

 foramen. The long surface for the brachialis anticus occupies 

 nearly the middle of the bone, and there is a small ectepicoudylar 

 tuberosity. 



Family STRIGTD^. 



All the genera are included in this family. 



Genus STRIX, Linn.' 



The tarso-metatarsu3 is long and slender, with a deep excavation 

 for the extensor hallucis, no bony bridge over the hollow for the 

 extensor communis digitorum, and short trochlea}. Tlie femur is of 

 moderate length, with the intermuscular ridge joiniug only the 

 inner trochlear ridge. 



The species are of comparatively small size. 



Strix melitensis, Lydekker, n. sp. 



Founded upon the femur, which is slightly longer and more 

 slender than that of S. Jlammea. The corresponding bone of 

 Sijrnium alaco is stouter and much more curved, with the great 

 trochanter inclined more inwardly, and the intermuscular ridge 

 less developed.
