Part III. — Eighteenth Annual Report 



same torm have been obtained. They are usually found in bottom tow- 

 net gatherings from the deeper parts of the Clyde. It now appears that 

 these Clyde specimens do not belong to Sars' Epinoeria tuberculata, but 

 are a deep-sea variety of Epimeria cornigera. They seem to form a con- 

 necting link between the two species named, and to belong nearly as 

 much to the one as to the other. It is a form which is in some respects as 

 handsome as typical specimens of either species, both in size and 

 coloration. 



EuSIRlDiE. 



Specimens of Eusirus longipes, Boeck, have been occasionally observed 

 during the year in bottom tow-net gatherings both from the Clyde and 

 Loch Fyne, but few of the specimens appeared to be mature. 



Gammarid^:. 



Maira othonis (M.-Edw), Cheirocrates intermedins, G. 0. Sais, and 

 Lilljeborgia kinahani (Spence Bate) have all been obtained in material 

 dredged at Tarbert Bank, Loch Fyne, at a depth of 15 to 17 fathoms. 

 Megaluropus agilis was captured in a tow-net gathering from the vicinity 

 of Sanda Island, Clyde, collected September 5th, 1899. 



Photid^e. 



Leptoehirus pilosus. — A few specimens of this species were recently 

 obtained in material from Tarbert Bank. In most of the Clyde specimens 

 I have seen, some of which were females with ova, the secondary branches 

 of the antennules are only two-jointed, the end joint being quite small. 

 Another species, Microprotopus maculatus, Norman, was obtained in a 

 bottom tow-net gathering, recently examined, collected in Aberdeen Bay 

 in May 1898. 



PODOCERID.E. 



Of species belonging to this group the following may be mentioned : — 

 Ischyrocerus minutus, which was obtained in the same gathering as that 

 in which the Microprotopus referred to above, was observed. Erichthonius 

 abditus occurred in a bottom tow-net gathering from 28 fathoms collected 

 in the vicinity of Ailsa Craig, Firth of Clyde, October 10th, 1899. 



Caprellid^e. 



Protella phasma (Mont.) is not very rare at Tarbert Bank, Loch Fyne. 

 There are few hauls with the dredge taken here in which it does not occur. 

 Caprella linearis (Linn.) was obtained at Inverneil Bay, Loch Fyne, by 

 Mr. F. G. Pearcey in November 1899. Males and females of the same 

 pecies have also been captured by the fishery steamer in the Morays 

 Firth. 



Caprella septentrionalis, Kroyer. — One specimen of this somewhat rare 

 species was captured in the Cromarty Firth on June 6th, and another on 

 November 23rd, 1898. I am not aware of any previous record of this 

 species for the East Coast of Scotland. 



Isopoda. 



There are few isopods to record. A considerable number of the 

 chelifera have been observed during the year, but most of the species to 

 which they belong have already been recorded. A few, however, require 

 further study.
