sharks and says, "it is remarkable, that this gigantic species, which 

 probably only occurs in deep water, has never been taken fresh in 

 Greenland waters". Stebbing (Tierreich, p. 73) records it "from Pro- 

 cellaria glacialis L., from stomachs of sharks, and fished up from 

 great depths". As the specimens of the Danmark Exped. come from 

 the stomach of a Fulmarus (Procellaria) glacialis, and this bird likes 

 to fly low over the surface, but does not dive (Kolthofif and Jäger- 

 skiöld, Nordens fåglar, 1898, p. 300), the specimens in question must 

 also have been taken at the surface, so that the species in any case 

 may rightly be called pelagic. Chevreux mentions a young specimen 

 from very great depths "Océan Atlantique, lat. 43°04' N., longit. 

 19°42'W., nasse, 5940 mètres" (Bull. Inst. Océanogr. Monaco, No. 156, 

 1910, p. 4). According to Sars ("Account") and Stebbing ("Tierreich") 

 the places where it has been found are the following: Greenland, 

 N. E. America, Spitzbergen, Finnmarken, Bay of Biscay, Azores, trop- 

 ical Atlantic (4° S., 18° W.), Cape Horn. 



Katiiis obesus has been taken by the "Tjalfe" at 6 localities at 

 W. Greenland (58°08' N.— 64°14'N.). It is also recorded from S. W. Ire- 

 land: 50 miles N. by W. of Eagle Island, Co. Mayo, 1200 fm. (Tatter- 

 sall 1906) and 36°17'N., 28°53' W. (Chevreux 1905). 



Paracyamus boopis lives on Megaptera boops. The host belongs 

 to the N. Atlantic : Greenland, Iceland, Finmarken, S. Europe, Ame- 

 rica. 



Aega crenulaia is known from W. Greenland and E. America to 

 Norway and goes southwards to S. W. Ireland (Tattersall 1995). 



Aega psora, Aega arctica and Aega ventrosa have the same distri- 

 bution; the last species goes right into the Kara Sea. 



Munnopsis typica seems to be circumpolar, being known from 

 arctic America and W.Greenland eastward to Siberia; further, it is 

 known from the Skager Rak and almost the whole of the rest of 

 the Norwegian coast. Perhaps, though it is pelagic, it should be 

 referred to Group 1 С See also Ohlin 1901, p. 32—33. 



Munneurycope Tjalfiensis has been taken in the mouth of the 

 Davis Strait 60°07' N., 48°26' W., 2000 m., vire out ("Tjalfe"). 



Eurycope robusta is known from W. and E. Greenland, eastern 

 N.America, Kara Sea, Norway and Skager Rak; belongs perhaps to 

 the Group I С 



Holophryxus Acanthephyrœ has been taken in the mouth of the 

 Davis Strait by the "Tjalfe" at the same place at Munneurycope 

 Tjalfiensis (see above). 



Holophryxus Richardii has been taken in Davis Strait 66°21^N., 

 56°30'W., 680 m., 800 m. wire out ("Tjalfe") and 33°4Г N., 36°55' W., 

 0— 2500 m. (Koehler 1911).
