 separate species. 



Centroscyllium, Fabricii Reinhardt. 

 {Squalus acanthias Fabricius (non Linné), Fauna Groenl., 1780, p. 126). 

 Local name in Greenland: Kukilik. 



West Greenland: The Copenhagen Zoological Museum contains from an earlier 

 period in addition to 3 embryos 5 large specimens (2 in spirit, 2 as skeletons and 1 stufled), 

 all females. The largest measures 675 mm^). None of these bears a notice of the local- 

 ity, but from old manuscript records it appears certain, that some of them have come 

 from the district of Julianehaab^). 



During the "Tjalfe" Expedition Centroscyllium Fabricii was obtained partly in the 

 Southern part of the Davis Strait outside Fyllas Bank, partly in Bredefjord and Kan- 

 gerdluarsuk in the northern part of the Julianehaab district. The separate localities 

 were as follows: 



St. 429. 63°54' N., 53°15' W., 520—737 fm. 3.7° G. 8. 6. 1909. Trawl. 3 spec. 

 St. 431. 63°24' N., 53°10' W., 470 fm. ca. 3.8° C. 9. 6. 1909. Trawl. 1 spec. 

 St. 549. Brede Fjord, from the north-eastern corner of the island Tugtutok over towards 

 the island Kekertarsuak, 100—300 fm. ca. 2.8—3.7° C. 22. 7. 1909. Lines. 4 spec. 

 St. 550. Bredefjord, Kangerdluarsuk, across the mouth. 100 — 250 fm. ca. 2.8 — 3.7° C. 



22. 7. 1909. Lines. Several spec. 

 St. 553. Bredefjord, Kangerdluarsuk. 120—200 fm. ca. 3.2—3.6° G. 25. 7. 1909. Lines. 

 5 spec. 



^) GuNTHER gives the length of a dried skin from Greenland preserved in the British Museum 

 as 29 English inches (ca. 736 mm). 



*) J. Reinhardt writes (K. D. Vidensk. Selsk. naturvidensk. og mathem. Afh., VII, 1838, 

 p. 132), that he had several times received this fish from Julianehaab and Frederikshaab; regarding 

 the capture of C. Fabricii at the last-mentioned locality, however, there is no information, nor 

 has the species been taken there later; the sender has perhaps obtained the fish from the 

 JuUanehaab district.
