Part III. — Seventeenth Annual Report 



Amphipoda. 



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

 forwarded to me from the " Garland " may now be referred to. 



The Hyperiidae were of rare occurrence in the tow-net gatherings 

 forwarded from the Clyde or Moray Firth during the past year. 

 Hyperia galba (Mont.), Hyperoche tauriformis (Bate), and Parathemisto 

 were observed in one or two of the Moray Firth gatherings, but in those 

 from the Clyde only Hyperoche and Parathemisto were observed, the 

 one from Stations I. and VIII. in both the surface and bottom tow-net 

 gatherings, and the other from Station VII. 



The Orchestiidaa observed include Orchestia mediterranean a species 

 that appears to be of rare occurrence in the Clyde district. One or two 

 specimens were obtained amongst decaying sea- weed, on the shore 

 between Fairlie and Hunterston in September. Orchestia mediterranea 

 is readily distinguished from the more common Orchestia littorea by the 

 form of the hands of the second gnathopoda in the male; in these 

 appendages the propodos are triangular instead of ovate ; the palm, 

 which is almost straight, extends from near the base of the propodos, and 

 has a triangular tooth-like projection anteriorly near the origin of the 

 claw. The claw is long and somewhat sinuate, and nearly of the same 

 length as the palm (figs. 9-11, PI. XIII., represent the anterior and posterior 

 gnathopods and one of the posterior pereiopods). 



Only two specimens of this species have been recorded from the Clyde 

 district by the late Dr. Robertson in Part I. of his Catalogue of Clyde 

 Amphipoda and Tsopoda. One of these he discovered at the west end of 

 Cumbrae ; the other was sent to him by Mr. John Smith, Kilwinning, 

 who obtained it at the mouth of the Garnock. 



A number of Amphipods belonging to the Lysianassidse have been 

 observed. I will, however, refer to only one of them — viz., the curious 

 Normanion quadrimanus (Bate and West wood), a single specimen of 

 which was obtained in a bottom tow-net gathering from Station I., 

 Firth of Clyde (near Davaar Island), collected 15th December 1898. 

 In Part II. of the late Dr. Robertson's Catalogue of the Clyde 

 Amphipoda, that author records having, along with the Rev. Dr Norman, 

 captured Normanion off Farland Point, Cumbrae, which seems to be 

 the only previous record of its occurrence in the Clyde. Professor Sars 

 has shewn that N. quadrimanus is parasitic in its habits, and states that 

 he has found it in great abundance clinging to the skin of fishes (both 

 living and dead) caught on a fishing line set in deep water. It may, 

 therefore, be found to be more common in the Clyde than it has hitherto 

 appeared to be if a careful examination were to be made of the fishes 

 caught in the deeper parts of the estuary. 



The Ampeliscidaa were represented in recent tow-net gatherings from 

 the Clyde by one or two moderately rare forms, such as Ampelisca 

 Icevigata, Lilljeborg; Ampelisca spinipcs, Boeck ; and Haploops tubicola, 

 Lilljeborg. 



Amongst the Phoxocephalidse the only species that need be referred to 

 is Harpina crenulata, Boeck. Four specimens of this Amphipod were 

 obtained in a gathering of Crustacea dredged in Campbeltown Loch 

 (Cantyre) in 1897. This appears to be the first record of H. crenulata for 

 the Clyde,
