OSTEOLOGIA AVIUM. 



[Menurin^:. 



Ribs broad at their upper extremities, and gradually becoming smaller towards 

 their lower ; styliform process broad at its attachment to the ribs, narrowed to the 

 point which projects over the rib behind it. 



Furculum arched anteriorly, slightly flattened, the rami widely divaricating without 

 any process at the j unction of the rami, united to point of the sternum by a ligament. 



Coracoids of moderate length and size, somewhat triangular in the centre. 



Scapula short, falciform, slightly expanding near their extremities, which point 

 downwards. 



Wing-bones short, strong, the humerus very slightly longer than the scapula; 

 metacarpus long in proportion to the humerus, radus, and ulna, the two bones forming 

 it only united at their extremities. 



Femur very straight; trochanters small, not projecting much upwards. Tibia 

 slightly bent downwards in the centre, an elongated projection on the inside near the 

 upper extremity, from which a small angular ridge proceeds downwards for about two- 

 thirds of the tibia. Metatarsus with the hinder part strongly edged on its external 

 and posterior margin, and also channelled posteriorly. 



Vertebral column of moderate strength, the penultimate and two following cervical 

 vertebrae with dorsal processes; the terminal caudal vertebrae very large, triangular.

I have only portions of the skeletons of this and the following species. 



Cranium very similar to that of Menura, but not so wide between the eyes ; occipital 

 ridge not so large ; occipital protuberance (which was broken in my skeleton of 

 Menura J large, from which, to the hollow at the base of the nasal bones, there is a 

 slight channel ; foramen magnum rounded. Palatine bones similar to Menura, as are 

 also the interarticular ones..
