PHALACROCORACID^. 51 



Tho humerus is long and slender, with the head elongated trans- 

 versely, no pneumatic foramen ; the surface for the origin of the 

 hrachialis anticus very long, with its outer portion produced into a 

 point superiorly, and its boundary running parallel to the outer 

 border of the bone (fig. 12) ; the condyles project far in advance of 

 the palmar surface of the bone, the radial one being large and 

 terminating in a crotchet, and the ulnar round. 



The ulna is characterized by the projecting and descending crochet 

 into which the radial proximal articular cavity is produced, and also 

 by the distinct ridge on tho opposite side of the shaft bounding the 

 long surface of tho hrachialis anticus : there is no foramen on the 

 palmar aspect of the proximal extremity. 



Phalacrocorax, sp. a. 



A large species probably identical \vith one of those now living in 

 New Zealand. The skuU resembles that of P. hicristatus.
