Specimens of Podocerus cumhrensis were obtained in the same Otter Spit 

 gathering with P. lierdmani. This is a small species, and the armature of 

 the posterior gnathopods in the male varies a good deal ; but, so far as I 

 could observe, the males of this Amphipod, notwithstanding the variation 

 referred to, could in every instance be distinguished from P. herdmani. 



Protella phasma (Montagu). This curious species has been recorded 

 from several parts of the Clyde area by the late Dr. Robertson, and may 

 also have been obtained in Loch Fyne, but I can find no reference to its 

 occurrence in that district amongst the published records within my reach. 



(4) The Ostracoda. 



Bairdia inflata, Norman. This Ostracod was obtained in dredged 

 material from Tarbert Bank, in 20 to 25 fathoms. It has also been 

 obtained from other parts of the Clyde area, but there does not appear to 

 be any previous record of it from Loch Fyne. 



Cythere tenera, Brady. I am indebted to Mrs. Robertson, of Millport, 

 for the record of this species from Loch Fyne. It is one of a group of 

 Ostracods usually found in water that is more or less brackish, and is 

 less frequent in the open sea. 



Cythere quadridentata, Baird. A few specimens were obtained in 

 material dredged at Tarbert Bank in the spring of last year (1897). 



Gytliere emaciala, Brady. Was found with the last species. It does 

 not appear to be very rare : the shells, however, were frequently coated 

 with mud, which may cause them at times to be overlooked ; but other 

 species — those with rough or spiny tests — found here were, many of 

 them, also more or less covered with mud. 



Cythere emarginata (G. O. Sars). Was obtained at Tarbert Bank with 

 the other species mentioned. Mrs. Robertson, of Millport, has also 

 favoured me with a MS. record of the same species for Loch Fyne. It 

 is probable that the Loch Fyne specimens are fossil, as the species, though 

 not rare in some glacial deposits, is apparently, as a recent species, more or 

 less restricted in its distribution to arctic or sub-arctic regions. 



Cythere dunelmensis (Norman). This also was obtained at Tarbert 

 Bank. It is probable that Cythere dunelmensis is not infrequent in Loch 

 Fyne, as it has a wide distribution — not only generally but throughout the 

 Clyde area ; but if the species has previously been obtained in Loch 

 Fyne, it is somewhat inexplicable that Loch Long, Rosneath, and 

 Rothesay Bay should be mentioned as Clyde habitats for the species, while 

 Loch Fyne, which is at least as important a locality as any of these, 

 should be omitted. 



Cythere lohitei (Baird). This is another of the species obtained at 

 Tarbert Bank, and which may be distinguished by the peculiar sculpture 

 of the shell. It does not appear to be a very common species. 



Cytherura simplex, Brady and Norman. I am indebted to Mrs. Robert- 

 son, of Millport, for the record of this species for Loch Fyne. A ''local 

 variety " of this species had been previously known as Cytherura sarsi^
