very few specimens are found in any single gathering. It occurred in four 

 of the series of gatherings at present under consideration, all the four 

 being from the Clyde, viz. : — In a gathering from Stations III. and IV., 

 collected on 24th August 1898 ; in a gathering from Station VII. collected 

 on 24th September; and in one from Station VIII., collected on 29th 

 of the same month. 



Photis longicaudatus (Spence Bate) occurred sparingly in a gathering 

 from Station IV., Firth of Clyde. 



Amongst the Podoceridge Podocerus palmatus, Stebbing and Robertson, 

 and Podocerus pusillus, G. 0. Sars, have been obtained in tow-net 

 gatherings from the Clyde— the first in a gathering from Station VII. 

 collected on 24th September 1898, and the other in a gathering from 

 Station VI., collected on 1st September. 



Unciola planic&ps, Norman, was obtained in the same gathering from 

 Station VI. in which Podocerus pusillus just recorded occurred. Unciola 

 appears to be an addition to the Amphipod fauna of the Clyde. 



Isopoda. 



The following are a few of the more interesting of the Isopoda that 

 have been observed in tow-net and other gatherings recently examined. 

 Those from the Clyde are, Leptognathia breviremis, Lillejeborg, collected 

 at Station XII., between the south end of Arran and the Ayrshire coast ; 

 Leptognathia hrevimana (Lilljeborg), at Station VI., 1st September 1898. 

 Another closely allied species — Tanaopsis laticaudata, G. 0. Sars — was 

 moderately f requen t amongst a gathering of material from Campbeltown Loch 

 (Cantyre) collected in May 1897. Munna boecki, Kroyer, which is larger 

 than Munna kroyeri, Goodsir, and apparently more frequent in the 

 Clyde, has been obtained at Whiting Bay, and one or two other places. 

 Both Munna boecki and Munna kroyeri have been observed in the 

 Moray Firth district. 



Paramunna bilobata, G. 0. Sars, recorded for the Clyde in 1894, by 

 the Eev. A. M. Norman (Ann. and Mag. Nat. Hist. (6), vol. xii., p. 

 280, footnote), was obtained at Station IV. (Kilbrennan Sound). It has 

 already been recorded for Loch Fyne in Part III. of the Sixteenth Annual 

 Report of the Fishery Board for Scotland. 



Pleurogonium rubicundum, G. 0. Sars, was recorded by the Rev. A. 

 M. Norman, for the Clyde, in 1894, in the same footnote in which Para- 

 munna is recorded (see reference under that species), and is, so far as I 

 know, the only record for the Clyde hitherto. Pleurogonium inerme, G. 

 0. Sars, has been obtained in a gathering from Campbeltown Loch (Can- 

 tyre), collected in 1897, and in one from Station IV. (Kilbrennan Sound), 

 collected on 24th August 1898. Pleurogonium spinosissimum, G. 0. 

 Sars, another of these minute Isopods, has been recorded for the Clyde 

 by the late Dr. Robertson, of Millport. 



Pseudione crenulata, G. 0. Sars (a parasite of Munida rugosa), 

 apparently new to Britain, and Pseudione affinis, G. O. Sars (parasite on 

 Pandalus montagui), have both been observed in the Clyde, while Bopy- 

 roicles hippolytis (Kroyer) has been obtained in the Moray Firth.
