452 On the Skeleton of the New-Zealand Pike Whale. 



notch in the middle, and with rounded ends. The sternum is' 

 6 J inches broad, 5 inches long ; the hinder part thick, cylin- 

 drical, about 2^ inches long, very different from that ot 

 Baloenoptera rostrata figured in the 'Catalogue of Seals and 

 Whales in the British Museum,' p. 110, fig. 12, c, more like the 

 sternum of Baloenoptera musculus. Van Beneden (Osteogr. 

 C^t. t. xii. fig. 14) ; but the upper part is more expanded, the 

 central notch rudimentary, and the stem longer and more 

 slender. 



The OS hyoides is 8^ inches wide and 3 inches long, dilated 

 in the middle, with a notch in the front edge somewhat as in 

 Balmnoptera rostrata (Osteogr. C^t. t. xii. fig. 4), but more 

 dilated in the middle, and with a process on each side of the 

 notch, to which is attached a flattened bone. M. van Beneden 

 does not figure any processes to the os hyoides of any of his 

 species in the * Osteographie ' similar to those found in the 

 skeleton from Otago. 



The scapula broad and low, the upper edge being about 

 one third of a circle, with well developed acromion and coracoid 

 processes. The glenoid cavity large, oblong ; the coracoid 

 blunt ; the acromion process coming from a ridge which 

 extends up the upper margin, elongate and broad. The width 

 15 inches, the height 9 inches ; the glenoid cavity 4^ by 

 2f inches. The scapula is rather broader and lower, and has 

 a smaller acromion process than that of B. rostrata figured by 

 Van Beneden (Osteogr. Get. t. xii. fig. 6). 



The bones of the fore fin are 28 inches long ; the humerus 

 6 inches, the ulna and radius 10 inches, the longest finger 

 10 inches. The first finger with three bony joints and one 

 cartilaginous one, the second with seven, the third (longest) 

 with eight, the fourth with four joints. 



There were sent with the skeleton a pair of ear-bones of 

 another Finner ; but they cannot belong to this skeleton, as 

 the skull has the left one attached, and Professor Hutton in- 

 forms me that one was unfortunately left behind, but it is on 

 its way to the Museum. The pair of ear-bones sent are very 

 like those of Megaptera novce-zelnndice^ 'Catalogue of Seals 

 and Whales,' p. 128, fig. 20.
