are Coronula diademct and Conchoderma auritum, both belong¬ 
ing to the group Cirripedia, and allied to the barnacles. The 
Coronula occurs often in large masses on the Humpback, 
especially round the snout and on the flippers, the individuals 
being sometimes sunk deep into the dermis, and sometimes 
projecting like large warts. 
The Right Whale of Greenland carries none of these 
Cirripedes, while its near ally the Biscayan Whale is usually 
infested with them; and the western wlialersused to distinguish 
between whales without “ calcareous plates” so called, these 
being the Greenland Whales, and those with “ calcareous 
plates,” the Biscayan Whales, or “ NordKaper ” as called by 
the Dutch and German whalers Sarde” of the Basques). 
The Humpback becomes early infested with these parasites ; 
in fact, some whalers have affirmed that they are born with 
them, but such a case of “ transmission of acquired character” 
is obviously highly improbable. 
The Conchoderma , which somewhat resembles the common 
ship’s barnacle ( Lepas anatifera), is usually found attached to 
the shells of the Coronulae, parasitic upon a parasite; or 
perhaps “ symbiotic ” more properly expresses this form of 
association. Almost every Humpback captured is infested 
with these two animals, sometimes to a marvellous extent. 
The third common parasite is a Cyamus, or “ Whale 
Louse ; ” this enjoys a free moving existence on the whales, 
either upon the surface, or burrowing a short distance below. 
A small Copepod is commonly found upon the baleen plates of 
the Blue Whale, and appears to be restricted to this species, 
unless we except Rudolphi’s Rorqual perhaps. It was 
described by Herr Aurivilius, of Upsala, and named 
Balcenophilus unisetus ( nov . gen . et sp.).* 
Various Entozoa occur, Echinorliynchi being most 
commonly met with, especially in Rudolplii’s Rorqual. 
I have given but a brief sketch of the natural history of 
these whales, as I wish now to turn to the question of their 
capture and conversion into merchandise.
