time to feel its helplessness, the victim was again 

 seized by the beak, which was twisted in the most 

 unmerciful manner ; and its remaining limbs were 

 taken hold of and wrenched in every direction until 

 torn off. When no other limbs were left to be torn 

 asunder, the denuded and lifeless trunk was dashed 

 in the most savage manner.

[Read 28th February, 1888.] 



Through the kindness of Dr. John Murray. Director 

 of the Challenge?* Expedition, I had lately the oppor- 

 tunity of examining some amphipods from the 

 Firth of Forth. As these gatherings were few in 

 number, and all taken about the same time and in 

 one locality, they cannot show much, but may 

 indicate what may be expected by further search. 

 I may be best able clearly to show the result by 

 giving a list of the species taken by one haul of 

 the tow-net attached to the beam of a trawl, at a 

 depth of 41 fathoms, 35 miles east of May Island, 

 Firth of Forth, on 11th November, 1887. Taking 

 them in the order of abundance, we have : 



Parathemisto oblivla, Kroyer. — Very common. 



Anonyx gulosus, Kroyer (=A. Holbolli, Bate). — 

 Common and large. 



Imphimedia obesa, Rathke. — Moderately common. 



Bathyporeia liobertsoni, Bate and Westwood (=B. 

 pilosa, Lindstrom, #). — A few. 



Tryphosa longipes, Bate. — A few. 



Monoculodes affinis, Bruzelius (=31. carinatus, Bate). 

 — A few. 



Halirages bispi7iosa, Bate. — Three. 



Ampelisca tenulcornis, Lilljeborg. — Two. 



Ampelisca Gaimardi, Bate (not Kroyer). — Two. 



Kroyera cdtamarina, Bate and Westwood. — Two. 



Orchomene serrata, Bate (not Kroyer). — One. 



Halimedon Mulleri, Boeck. — One. 



Metopa gregaria, G. O. Sars. — One.
