G-enus Amathilla, Spence Bate, 1863. 



Amathilla homaei (Fahricius). 



1779. Astacus homari, Fabricius (27), p. 247. 

 fJ|This species was obtained off West Point, Cape Flora, in 2 to 

 4 fathoms, on two different occasions, viz., on June 22nd and 

 July 5tli, 1897. 



Amathilla pingtjis {Kroyer). (Pl./^ figs. 14, 15.) 

 . 1838. Gammarus pinguis^ Kroyer (41), p. 24, pi. 1. fig. 5. 



This Amathilla was represented by several specimens captured 

 in the neighbourhood of Cape Flora on different occasions during 

 June and July, 1897. Prof. (x. O. Sars states that this species 

 ought, in his opinion, to be removed as the type of a separate 

 genus, as it differs considerably in several points " from the 

 typical AviatTiillaP In Amathilla pinguis the last epimeral 

 plates of the metasome somewhat resemble those of Apherusa 

 Jurinei. 



G-enus G-ammaracanthus, Spence Bate, 1862. 



Gammaeacanthus loricatus (Sabine). 



1824. Gammarus loricatus, Sabine (65), p. 131, pi. 1. fig. 7. 



A single specimen of this fine species was captured about 50 

 yards off West Point, Cape Flora, in 2 to 3 fathoms, on June 

 22ud, 1897. G. loricatus appears, in its distribution, to be 

 restricted to the Arctic seas, and is not even recorded from the 

 coast of Finmark, a district that has furnished not a few Arctic 

 forms to the fauna of Norway . 



'^Genus Gammarus, Fahricius. 



Gammartjs loousta (Linne). 



1767. Cancer locusta, Linn6 (50), p. 1055, 



Numerous examples of G-ammarus locusta, comprising all 

 stages from embryos to adults, were included in the Bruce 

 collection. Nearly all the specimens were from inshore, and 

 formed part of every inshore gathering of invertebrates. Some 

 of the specimens were of large size, while a considerable pro- 

 portion of the adult females carried ova or embryos. Prof, Sars 

 includes Franz-Josef Laud in his notes on the Arctic distribution 

 of Gammarus locusta.
