401 Part III. — Eighteenth Annual Report 



Parartotrogus richardi, T. aiid A. Scott. 



1893. Parartotrogus richardi, T. and A. Scott, Ann. and Mag. 

 Nat. Hist. (6), vol. xl., p. 210, PI. VII. 



This curious little species has not before been observed in the Clyde 

 area. It is a form that is readily missed, and may therefore be more 

 widely distributed than at present it appears to be. In Scotland it has 

 only hitherto been observed in the Firth of Forth, but it has also been 

 found in the vicinity of Naples by Dr. W. Giesbrecht. 



Amphipoda. 



A few of the amphipods observed in the tow-net and other gatherings 

 sent from the Fishery steamer " Garland " may now be noticed. Only the 

 rarer forms are recorded here. 



HyPERIIDjE. 



Hyperia galba, Parathemisto (1) oblivia, and Hyperoche tauriformis 

 have been occasionally observed in the tow-net gatherings sent from the 

 Clyde and Loch Fyne. These may still be reckoned as comparatively 

 rare amphipods in the Clyde area. Their scarcity here is in somewhat 

 marked contrast to the frequency of the species on the East Coast. 



PONTOPOREIHLE. 



Urothoe marina has been obtained at Tarbert Bank, Loch Fyne, while 

 Argissa hamatipes (Norman) has been observed in tow-net gatherings 

 collected both iu Loch Fyne and in the seaward portion of the Clyde 

 estuary. Argissa is sometimes frequent in under surface tow-net 

 gatherings from the Clyde. The somewhat remarkable difference in the 

 dorsal aspect of the urosome in the male and female is an interesting 

 feature of this species. Argissa was also obtained in a towmet gathering 

 collected in Aberdeen Bay in May 1898. 



Amphilochid^:. 



A number of species belonging to this group have been observed in the 

 gathering of tow-netted and dredged material sent from the " Garland " 

 during the past year. One of these appears to be identical with a form 

 discovered a few years ago in the Moray Firth. This form was described 

 in the " Annals and Magazine of Natural History " * under the name of 

 (?) Cyproidia brevirostris, T. and A. Scott ; it is a very small amphipod, 

 scarcely reaching to two millimetres in length ; the Clyde specimens, which 

 are of a somewhat chocolate-brown colour are easily overlooked. 

 Cyproidia brevirostris comes very near Cyproidia danmoniensis, Stebbing. 

 Stegopla.f longirostris, G. 0. Sars, is also another closely allied form. 

 A few specimens of Cyproidia brevirostris were obtained in some dredged 

 material from Tarbert Bank, Loch Fyne — a rocky bank wmich rises to 

 within 15 or 17 fathoms of the surface, while all around the water is 

 deep. This amphipod has not before been recorded from the Clyde area. 



Epimerice. 



Epimeria cornigera (Fabricius), var. In Part III. of the Fifteenth 

 Annual Report of the Fishery Board for Scotland (1897), p. 169, I 

 recorded from the Clyde a specimen of what appeared to be Epimeria 

 tuberculata, G. 0. Sars ; and since then a few more specimens of the 



* Ser. 6, vol. xii., p. 244, Pi. XIII. (1893).
