is short and of little value. Though one of the most common Whales 

 on the Greenland coast, yet, on this account and being difficult to 

 capture, it is rarely troubled. 



6. Catodon macrocephalus, Lace'p. 



Physeter macrocephalus, Linn. Syst. N. i. p. 10/ ; O. Fab. Fauna 

 G-rcenl. p. 41. 



Popular names. — Sperm-Whale (English) ; Kegutilik (Green - 

 landers). It is probably also the Potvisch (Norse), and Tweld-Hval 

 (Icelandic). 



Though currently reported in all compilations as one of the most 

 common animals of the Arctic seas, and especially of Davis Strait 

 and Baffin's Bay, it can only be ranked as a very rare, and possibly 

 accidental, straggler. Whatever it was formerly, it is now only 

 known to Davis-Strait whalers by name ; many will even ridicule 

 the notion of its being an inhabitant of those seas. I found very 

 few Eskimo who knew it even by tradition ; and I could only hear 

 of one recent instance of its being killed on the coast of Greenland, 

 viz. near Proven (72° N. lat.) in 1857. 



7. Delphinus EUPHROSYNE, Gray. 



DelpJdnus holboHii, Eschricht, Skand. Naturf. Mode i Kjobenhavn, 

 1847, p. 611. 



This species is only known as a member of the Greenland fauna 

 by a skeleton from South Greenland. It is apparently unknown to 

 the natives, for they have no popular names for it. 



8. Lagenorhynchus albirostris. Gray. 



Delpkinm ibsenii, Eschricht, Unders. over Hvald. b^ Af h. i Vid. 

 Selsk. Nat. Math. Afh. xii. 297. 



This is only known as a Cetacean of Davis Strait by a skeleton 

 from Greenland in the Copenhagen Museum. It is found also in the 

 Faroe Islands, and in various portions of the North Sea. 



9. Lagenorhynchus leucopleurus (Rasch), Gray. 



Dr. Gray* has referred a skeleton from Greenland in Mr. Brandt's 

 collection to this species, and on his authority solely I claim it as a 

 member of the Greenland fauna. We possess no particulars of its 

 history as an Arctic animal. The Norwegians know it as the 

 Qwitskjoeving.
