6 Mindeskrift for J. Steenstrup. XXX. 



to Reinhardt some sharks, regarding which there could be no doubt that they were 

 Fabricius' Squalus acanthias, "on the one hånd, because they had the Greenlandic name 

 given them in the fauna of Fabricius {Kukilik), on the other, because they were just 

 taken frequently in the manner described by him, namely, in winter through holes in 

 the ice ("capitur tamen praesertim hierne per foramina glaciei")". Jørgensen adds 

 further, that this species of shark occurs in great quantities in the Narssak district in 

 the neighbourhood of Tunugdharfik. 



The specimens referred to by Jørgensen and sent down by him are still present 

 in the Zoological Museum's collection of Greenland fishes; one specimen is an adult 

 female, two others are embryos (the one 124 mm in length, the other somewhat smaller)

 4 diameters. From a specimen from Davis Strait (63°54'N. 63°16'W.), 520 — 737 fm. 



according to Jørgensen's statement "taken from the stomach(!) of the mother at Noug- 

 miuti) in February 1839". 



As the specimens sent by Jørgensen belong to Spinax Fabricii Reinhardt, the ques- 

 tion is thus fmally settled: Fabricius' "Squalus acanthias'" is not identical with Linné's 

 species of the same name, but with the Spinax Fabricii described by Reinhardt. 



During my stay at Narssak itself in the summer of 1909, when we several times ob- 

 tained Centroscyllium Fabricii on lines, I got it confirmed, that Jørgensen's account 

 was perfectly correct: the Greenlanders at this settlement know this shark well and, 

 they call it Kukilik. 



General Distribution. Centroscyllium Fabricii is an Atlantic species. In 



') Nougmiut lies north bf Narssak, on the north-west corner of the peninsula Ihmausak.
