to RpuNHAKDT soiiie sharks, regarding which there couhi lie no doubt that they were 

 Fabricius' Sqiialus acanthias, "on the one liand, 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 hieme per foramina glaciei")". Jorgbnsen adds 

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

 the neighbourhood of Tunugdliarfik. 



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

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

 female, two otliers are embryos (the one T24 mm in length, the other somewhat smaller)

4 diameters. From a specimen from Davis Strait ((i3°.54' N. .')3°1.5' W.), 520 — 737 fm. 



according lo Jokgknskn's statement "taken froin the sl(imach(!) of the nn)ther at Noug- 

 miuti) in February 1839". 



As the specimens sent by Jorgensen belong In Spiini.r Fabricii Reinhardt, the ques- 

 tion is thus finally settled: Fabricius' "iSqualus (irdiithins" is not identical with Linne's 

 species of the same name, but with the Spinax Fahncii described by REiNHARnT. 



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

 tained Cenlrusajlliiuii Fabricii on lines, I got it confirmed, that Jorgensen's account 

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

 they call it Kukilik.

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