Two individuals of this species were taken near Honfleur, 

 in France, in 1788. Two more have been stranded near 

 Caen, one of them in 1842, the skeletons of which are in 

 the Paris and Caen museums. One was taken on the 

 Dutch coast in July 1846. The Bottle-head has been 

 taken a few times on the east coast of England, and more 

 frequently on the north-east coast of Ireland. In the 

 'Illustrated London News' of February 17, 1855, is an 

 account of an individual taken a short time previously in 

 Solway Frith, which measured 25 feet in length, with a 

 girth of 16 feet.
