Aberdeen, in October and November last year. The species occurred in 

 a gathering from 36 to 49 fathoms collected on October the 23rd, in 

 another from 60 fathoms collected on the 25th of the same month, and in 

 a third gathering from 45 fathoms collected on November 7th. These 

 gatherings were collected by the Fishery steamer "Garland." 



Metopella nasuta (Boeck). 



This small species was moderately common in a gathering collected off 

 Fair Island, in 80 to 85 fathoms, on October 12th, 1900. It was also 

 obtained in some bottom tow-net material, collected about sixty-five 

 miles to the south-east of Sumburgh Head, on September 4th, by the 

 steam trawler " St. Andrew." 



Metopina robusta (G. 0. Sars). 



This somewhat rare species occurred in one of the gatherings from the 

 Fishery steamer " Garland," collected off Aberdeen, in 45 fathoms, 

 November 7th, 1900. The Rev. A. M. Norman has instituted the new 

 genus — Metopina — for this form,* and one of its principal characters is 

 the peculiar structure of the first gnathopods. There appear to be only 

 three British records for Metopina robusta previous to this one, viz. : — 

 The Firth of Forth, where it was obtained by Dr. Henderson in 1884, 

 and the Moray Firth, where it was dredged by the " Garland" in 1893,f 

 and again in 1899. J The gathering in which it occurred in 1893 was 

 collected a few miles to the north of Rosehearty, but the gathering 

 collected in 1899 was from Station XV., in the vicinity of Smith Bank. 



Lbucothoid^e. 



Leucothoe lilljeborgii, Boeck. 



This was obtained in a tow-net gathering collected about fifty miles 

 south-south-east of Fair Island, October 16th, 1900. There does not 

 appear to be any previous record of L. lilljeborgii from this part of the 

 North Sea. 



GEmCERIDiE. 



Aceros pliyllonyx (M. Sars). 



Although a number of species belonging to the (Ediceridas have beeu 

 observed in the various tow-net gatherings examined, and notes taken of 

 them, they are rather more common than the one specially referred to. 

 Aceros yhyllonyx appears to be comparatively rare as a British species ; 

 the only British record known to me is that of Metzger of the German 

 North Sea Expedition, who obtained it " sixty miles north of Peterhead." 

 During the Fishery Board's recent investigations eastward of Fair Island, 

 Aceros was obtained on two occasions in bottom tow-net gatherings, 

 collected on the 12th October about fifty miles south-south-east of Fair 

 Island, in 80 to 85 fathoms. A number of specimens were obtained, but 

 all were more or less damaged ; they were, however, sufficiently perfect 

 for identification.

 be noted, however, that Metopina has already been used by Macquart for a genus of 

 insects.
