Balaena Hectori and Megaptera novae-zelandige. 57 



a sliort, thick, conical coracoid process near the glenoid cavity, 

 which would lead to the idea that it is a distinct species not 

 hitherto recorded as occurring in New Zealand. I propose to 

 call it Bahena Hectori. 



Bladebone of BaJana Hectori. 



I call this species Balcena because I do not know any of the 

 existing genera to which it can be refeiTcd, and think that 

 when we know more of the skeleton to which it belongs it 

 will most probably be the type of a new genus of Balanidfe. 



This bladebone, from its small size, may be that of Xeo- 

 halama marginata^ the pigmy New-Zealand whale, which was 

 first known from three blades of whalebone, then from its ear- 

 bone, and at last by the discovery of the whole skull ; but the 

 rest of the skeleton is still unknown ; and the possession of an 

 acromion process to the scapula, which is not found in any 

 other true whale, would agree with the anomalous form of the 

 bones of the head of that whale. 



The other drawing represents a scapula about 2| feet high and 

 4 feet wide at its upper edge, which the New-Zealand wlialers 

 said belonged to the black whale ; and Dr. Hector says it 

 agrees with the scapula that Dr. Knox gave to the museum 

 of the New-Zealand Institute just before he died as that of the 

 black whale. It doubtless belonged to the whale which he so 

 called in his papers. 



This figure rc})resents the scapula of a species of Megaptera ; 

 for it agrees with it in its broad oblique outline, and in being 

 destitute of any coracoid or acromion process, or any rudiments 

 of them, like the rudimentary acromion process found in the 

 Poiscopia Lalandii of the Cape seas. It is most probably the 

 scapula of the Megaptera noviR-zelandio'^ C'^i'ay (Cat. Seals and 

 \Viiales,p. 128, fig. 20), which I established on an ear-bone
