Tursio metis, Gray. 



The specimen here described was presented to the Otago 

 Museum by Captain Fairchild, of the Colonial steamer ' Luna,' 

 and is one of two captured in Useless Bay, Dusky Sound, on 

 the 10th of May, 1875. The other specimen was also a female, 

 and measured 9| feet in length ; on being captured it emitted 

 large quantities of milk. 



The following are the dimensions of the skull : —

The skull agrees very well with the figure of that of T. metis 

 in the ' Zoology of the Voyage of the Erebus and Terror ;' but 

 the teeth are rather closer together.
