 the British seas annually. Coast of Hampshire, 184*2. Plymouth,

 Humber (skeleton of young, 50 feet long, in Mus. Hull). Lon- 

 donderry; Turner. In 1847 1 had the opportunity of examining 

 the skeleton of a large male whale, 78 feet long, which Dr. Knox 

 described as Baltena maxima-borealis, then suspended in the 

 Zoological Gardens, Edinburgh, and pointed out its difference 

 from the skeleton of Physalus Antiquorum, and proposed to call it 

 P. borealis (P. Z. S. 1847, p. 117). Professor Turner, who has 

 lately had the opportunity of examining the skeleton more closely, 

 says it is the same as Cuvierius Sibbaldii.
