"The specimen from which this description was taken was obtained in Ad- 

 miralty Inlet, Washington Territory, October, 1870. It was a female, and con- 

 tained a foetus five feet long; thus correcting the error of the whalers, who com- 

 monly regard this small species as the young of the 'finback' of the coast. The 

 skull has been deposited in the National Museum at Washington." (81, 269-270.)
