List of the Species of the Crustacea obtained in the Gatherings from Loch 

 Fyne described in the preceding Notes. 



COPEPODA. 



Nearly all the Copepoda observed belong to the division Calanoida, 

 G. 0. Sars. Two species belong to the Harpacticoida, one to the Cyclopoida, 

 and one to the Monstrilloida. 



Calanoida. 



Calanus septentrionalis (Goodsir). This is the Galanus helgolandicus of 

 Claus, but Goodsir's is the older name. It does not difler greatly from 

 C. finmarchicus (Gunner), and perhaps should be still included in that 

 species. It is the most common and generally distributed species in our 

 seas, and it is also the most important, as it forms a large part of the food 

 of the herring. 



Faracalanus parvus, Claus. This small species occurred in gatherings 

 from Stations V. and VI. and one or two other stations, but always rather 

 sparingly . 



Pseudoccdanus elongatus, Boeck. This species is generally distributed, 

 and sometimes moderately common in Loch Fyne. It occurred in most of 

 the gatherings examined. 



Bradyidius armatus, Vanhoffen. This species occurred sparingly' at 

 Stations II., V., and VI., and one or two other stations. 



Euchasta norvegica, Boeck. Plentiful in large " mid-water" and "ring" 

 net gatherings collected off Inveraray and Newton in October 1906, and 

 more or less sparingly in gatherings collected with the ordinary tow-net, 

 at most of the stations referred to in the preceding notes. 



Diaixis pygmazus (T. Scott). Bare in a bottom gathering collected at 

 Station IV., Upper Loch Fyne, March 1905. 



Centropages typicus, Kroyer. This species appeared to be rare in Loch 

 Fyne. The only gathering in which it was observed was in a vertical haul 

 from 15 fathoms collected at Station II. in August 1905. Mr. W. L. 

 Calderwood has also recorded this species from E. Loch Tarbert (Lower 

 Loch Fvne). 15th Annual Report, Fishery Board for Scotland, Part III., 

 p. 146 (1897). 



Centropages hamatus (Lillj.). This occurred in many of the gatherings 

 examined, and was occasionally moderately frequent. 



Temora longicornis (0. F. Muller). Temora was observed sparingly in 

 gatherings from several stations, and appeared to be generally distributed. 



Metridia lucens, Boeck, occurred rather sparingly in gatherings collected 

 at Stations II., III., V., and VI., and at one or two other stations. 



Anomalocera pater soni, Tempi., was obtained usually in surface gather- 

 ings or in gatherings from near the surface at several stations, but always 

 in small numbers. 



Parapontella brevicornis (Lubbock). This was one of the rarer species 

 observed. It occurred in gatherings from Stations II., III., and VI., and 

 one or two other stations. 



Acartia clausi, Giesbrecht. Hitherto this is the only species of Acartia 

 that has been recorded from Loch Fyne. Is occurred, though somewhat 

 sparingly, in a large proportion of the gatherings examined. 



Harpacticoida. 



Zosime typica, Boeck. This species was observed in a gathering from 

 Station V. in 1905. 



Harpacticus uniremis, Kroyer. This species occurred in a gathering 

 collected off Skate Island.
