an Anonyx from the laminarian zone in the Out Skerries Harbour, 

 procured in 1861.

 Lilljeborg is unquestionably right in considering the A. ampulla of the 

 ' British Sessile-eyed Crustacea' to be the male of A. longipes. I have 

 taken both sexes in Balta Sound and in St. Magnus Bay. The true 

 A. ampulla of Kroyer is the next species which is now added for the 

 first time to our fauna.

This Anonyx, the specimens agreeing in all respects with Spitzber- 

 gen examples, received from Prof. Loven, except that they are not more 

 than a quarter the size, was procured on the Out Skerries Middle Haaf, 

 in 1861. It occurred in hundreds upon a fish which had been brought up 

 dead on a fisherman's long line. It would appear to be one of the 

 scavengers of the seas ; for Goes also writes of it, " Ad Spetsbergiam 

 inter algas, prsesertim fundo arenoso et argillaceo profunditate orgyarum 

 trium usque ad sexaginta copia stupenda, eo ut, si perite ac prudenter in 

 captura versaris, hos pelagi voracissimos vespellones molibus milliariis 

 cadavere avium vel phocarum brevi e fundo elicere potes." The contour 

 of this Anonyx is peculiarly rounded and smooth, by which character it 

 may, without microscopic examination of the limbs, be distinguished 

 from longipes. It is now first added to our fauna.
