The Metopa which Bate and Westwood figured as Leuco- 

 thoe norvegica, Lilljeborg, was the male of 31. Alderi, and to 

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

 his reieren'ce to Bate and Westwood's figure it would almost 

 i^eem 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: — " Z. clypcatce, Krojer, sat affinis. 

 Antenna superiores inferioribus longiores, flagello pedunculo 

 longiore, articulo primo secundum superante, et articulo tertio 

 niinimo; flagellum antenni inferi ultimo pedunculi articulo 

 brevius vel sequale ; manus pedum secundi paris maxima;, 

 dilatatge, ajAce vero acuminato, aculeoque marginis posterioris 

 medii validissimo et ungui cequali ; epimera quarti annuli 

 thoracici maxima, latitudine vero altitadine parum majore.^'' 

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

 the statement as to comparative lengths of the antennge should 

 also be italicized. The figure represents a second gnathopod 

 with the palm projected forwards and the lateral process 

 reaching beyond the palm (c/. Sars's figure p.^ <?), so that 

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

 the case. 



Hah. Shetland ; near Holy Island, Northumberland ; 

 Durham coast {A. M. N.) ; Aberdeen [R. Daioson) : Mus. 

 Nor. St. Andrews {M'Intosh) ; Firth of Forth {T. S.). 

 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.
