Hector. — Notes on New Zealand Wlmles. 259 



succeeding vertebrae quadrate, but wider than high ; neural arches of the six 

 posterior cervicals are thin with imperfectly developed central and lateral 

 spines ; eighth and ninth vertebrae have feeble neural spines, and the lateral 

 processes expanded at the tip vertically ; the lateral processes of the tenth 

 and succeeding vertebrae are expanded in the horizontal plane, the tenth to 

 twenty-second having articular facets excavated on their lower marginal 

 surface ; the first lumbar is only distinguished by having an articular facet. 



Ribs fifteen, two belonging to the left side being lost; the first rib is 

 broad and short and with a single elongated articular surface ; the second and 

 third have a strong expanded articular angle and a subcylindrical compressed 

 capitulum ; all the rest of the ribs have a blunt subquadrate articular surface ; 

 the seventh rib is longest, being more than twice the length of the first, and 

 one-third longer than the fifteenth ; the thirteenth, fourteenth, and fifteenth 

 ribs are narrow, and irregular in outline and curvature. 



The total number of vertebrae is fifty-seven ; the chevron bones begin on 

 the forty-second, and the neural arch disappears on the fifty-second ; the lateral 

 processes cease to be prominent on the forty-third, and are perforated by a 

 foramen on the forty-fourth and succeeding vertebrae that have a lateral 

 process. 



The scapula is triangular, wider than high ; the posterior edge is set at an 

 angle of forty-five degrees to the plane of the glenoid cavity, and the anterior 

 edge at seventy degrees ; it has a strong curved and compressed acromion 

 twice as long as a moderate pointed coracoid process, which is half the length 

 of the fore and aft diameter of the glenoid cavity, and equal to its transverse 

 diameter ; the external surface of the scapula is rather concave, and both are 

 marked by obscure ridges. 



The humerus is stout and half the length of the fore-arm, which is equal 



h of the manus, which latter has four fii 



The sternum is triangular with four articulations, and is attenuated 



bone 



The total length of the 



skeleton without the skull, which measures 17 feet, is 50 feet 6 inches ; the 

 cervical region occupies 2i inches.
