The Metopa which Bate and Westwood figured as Leuco- 

 thoe norvegica, Lilljeborg, was the male of M. Alderi, and to 

 that species Sars has referred Lilljeborg's species; but from 

 his reference to Bate and Westwood's figure it would almost 

 seem that he had not consulted Lilljeborg's papers. That 

 author's Leucothoe norvegica is, it appears to me, undoubtedly 

 the present species. The following description applies to it, 

 and not to M. Alderi : — "L, clypeatce, Kroyer, sat affinis. 

 Antennas superiores inferioribus longiores, flagello pedunculo 

 longiore, articulo primo secundum superante, et articulo tertio 

 minimo ; flagellum antenni inferi ultimo pedunculi articulo 

 brevius vel gequale ; manus pedum secundi paris maxima?, 

 dilatatse, apice vero acuminate, aculeoque marginis posterioris 

 medii validissimo et ungui osquali ; epimera quarti annuli 

 thoracici maxima, latitudine vero altitudine parum majore" 

 The italics are Lilljeborg's, but for comparison with M. Alderi 

 the statement as to comparative lengths of the antennas should 

 also be italicized. The figure represents a second gnathopod 

 with the palm projected forwards and the lateral process 

 reaching beyond the palm (cf. Sars's figure p. 2 $), so that 

 the finger impinges upon it ; and in no other species is this 

 the case. 



Hab. Shetland ; near Hoiy Island, Northumberland ; 

 Durham coast (A. M. JS.) ; Aberdeen (B. Dawson) : Mus. 

 Nor. St. Andrews (M'lntosh) ; Firth of Forth (T. 8.). 

 There is thus no record of it as yet from the west side of our 

 islands except St. Ives, whence Spence Bate received 

 specimens from Mr. George Barlee. 



Distrib. Bejan, at entrance of Trondhjem Fiord, Norway, 

 in 30-50 fathoms (G. O. Sars) ; Tromso (Sch?ieider) • Green- 

 land (IJ. J. Hansen) ; Murman coast {Jarzinski, fide Sars).
