NOTES AND MEMORANDA. 283 



ratter rare on the North Sea grounds^ since the Grimsby fishermen 

 are quite unacquainted with it. The specimens I have alluded to 

 were regarded as hybrids between a tusk and a haddock. —

A specimen 18^ inches in length has also been received at 

 Plymouth. It was taken on a whiting hook^ 5 miles from shore on 

 hard ground. — W. L. C. 



Sebastes norvegicus (Ascau).— The Norway '^haddock" seems to 

 be rather common in the deep water about the Fisher Bank^ but has 

 no vernacular name amongst the Grimsby fishermen. 



Crystallogobius Nilssonii (Diib. and Kor.). — Mr. Cunningham's remarks 

 on the distribution of this form^ in the last number of the Journal, 

 will be remembered. I have recently been able to show that it is 

 very generally distributed, at depths from 10 to 35 fathoms, along 

 the west coast of Ireland (loc. cit., p. 284), and am now able to 

 record it from the '^ Head ^^ ground, 15 to 20 miles E.S.E. of 

 Flamborough Head, 29 fathoms, having trawled a perfect specimen 

 there on the 19th March. I have seen fragments, which I suppose 

 to belong to the same species, adhering to the nets of boats returning 

 from other grounds, and suspect that the use of suitable nets would 

 show that it is pretty common. The fishermen told me that they 

 considered such fish as my specimen to be young haddocks, but 

 the resemblance to a young herring or sprat is more obvious.

Arnoglossus laterna (Walb). — I received a specimen from 35 miles 

 off Flamborough Head, 33 fathoms, on the 20th February. The 

 species does not seem to have been recorded from the east coast of 

 England, though it occurs in Norwegian waters, and has been taken 

 off the coast of Banffshire.— B. W. L. H. 



Raia alba (Lacep.). — On the 29th of February, when looking over a 

 very large '' take " of skates landed on the Plymouth Barbican, I was 

 fortunate enough to notice a fair-sized specimen of this our largest, 

 though seldom observed, British species. It measured 6 feet 2\ inches 

 extreme length, and 5 feet 1 inch across the wings. The colour in 

 the dorsal surface was a dull brownish grey. The ventral surface 

 was a dead white on every part except where the extreme margin 

 of the fins showed a translucent red. The specimen was a female, 

 but had the characteristic sharp teeth seen in both sexes of this 

 species. On the under side, from the level of the mouth to the tip 

 of the snout, there was a thick covering of spines, and fully half-
