In these 12 speeiniens the number uf I lie scapular spines is constant, 2 on each side. 

 Of the postorbital spines there are always 2 on each side, of the preorbital spines most 

 frequently 2, sometimes only 1 on each side. Three specimens have 18 spines along 

 the mid line of the back and tail, the others have 14 — 16. Two specimens possess a 

 well-developed spine between the dorsal fins. 



During the "Tjalfe" Expedition Raja radiata was frequently obtained along 

 the stretch from Ilua up to Disko Bugt (oU 55'— 6S)°17' N.). It was caught on lines 



in the following fjords: the fjord 

 at Ilua, Agdluitsok, Tunugdharlik 

 (from the mouth right into Musar- 

 tuit), Bredefjord (with Kangerd- 

 luarsuk and Sermilik), Ivvanefjord 

 S. of Frederikshaab, Godthaabs- 

 fjord (right into Kugssuk beyond 

 Kornok);the depths were 30 — 125 

 to 830 fm. Further, it was taken 

 with the trawl between Fyllas Bank 

 and the land (63°48' N., 52°23' W.) 

 at ca. 100 fm., in the middle of the 

 Davis Strait (66°45' N., 56°30' W.) 

 at ca. 200 fm., as also in the 

 southern part of Disko Bay at ca. 

 150—230 fm. The Starry Ray 

 was very common especially in 

 the fjords round the settlement 

 Narssak ' ) in the district of Juliane- 

 haab, and up to 20 could be taken 

 on the long-line. The largest of 

 all the specimens taken by the Expedition was a male of 610 mm, whilst the largest 

 female measured 590 mm''). The number of spines along the mid line of the back and 

 tail varied (in 44 specimens) from 13 — 19; sometimes also there was a spine between 

 the dorsal fins. The other large spines were only counted in 7 specimens, where there 

 were 2 scapular spines, 1 pre- and 2 ])ostorbital sjtines. 



') The Greenlanders at this place know this fish well; they call it "Taralikisdk". Its abun- 

 dance here was also known already to Fabricius : "It lives in the southern deep fjords, esiiecially 

 at Tunnudliorbik" (= Tunugdliarfik). 



-) The .smallest specimen was only 109 mm long, taken at 69°17'N'., 52°14'W., 227—234 fm; 

 behind the dorsal flns it has a tail-end of 16 mm (see note 2 antea p. 17).
