66 ANNALS OF SCOTTISH NATURAL HISTORY 



By the kindness of Mr. Theodore Salvesen of Leith I 

 am able to give the results of whales killed at Captain Bull's 

 station at Nordfjord, East Iceland, for 1906. This is inter- 

 esting for comparison : 1 2 B. sibbaldii, 23 B. musculus, 25 

 Megaptera, \ B. borealis. Mr. Salvesen also sends me the 

 catch made at the Thorsvig station at Faroe : 3 B. sibbaldii, 

 24 B, musculus, i 8 B. borealis, 3 Bottle-nose. 



Norrona station had Finner cow whales of lengths of 

 70, 70, 70, 71, 72, 70, 72, 70 feet, but the two largest 

 bulls were 68 feet each. 



Shetland station had cows of 72 and 73 feet, but the 

 largest bull was 65 feet. 



Alexandra station had cows of 71, 70, 70 feet, the two 

 longest bulls being 70 and 69 feet. 



Bunaveneader station had cows 73, 71, 71, 70, 70 feet 

 the three largest bulls being 69 feet each. Taking these 

 with what I have recorded in former years, there can be no 

 doubt that cows of B. musailus attain a greater size than 

 the bulls ; and on an average of all the bulls and cows the 

 latter will be found, as a rule, to be about 3 feet longer than 

 the bulls. 



MIGRATION. 



The migration of whales is a difficult subject to handle, 

 for we know really very little about the movements of most 

 whales. All that I attempt to do is to put the little I 

 know before the reader and allow him to draw his own con- 

 clusions. 



In the Antarctic, Megaptera, B. sibbaldii, and B. imisailus 

 are very common. Sperm Whales are scarce, though often 

 seen near the River Plate. Balcena biscayensis is said to be 

 found near the south coast of South America during March, 

 April, and May. Again, on the west coast of Africa, Sperms 

 and Bal&na biscayensis are found. Off the coast of Brazil, 

 Megaptera are numerous. Off Tristan da Cunha, Sperm 

 and Atlantic Right Whales are said to be abundant. In 

 south latitudes Finners, Blue Whales, Megaptera, Bottle- 

 nose, Sperm Whales, and Atlantic Right Whales are all 

 seen. But the Balcenoptera borealis does not seem to be 

 known. It is but right to mention that the Dundee
