Part III. — Sixteenth Annual Report 



I have, as formerly, to acknowledge my indebtedness to several friends 

 for kind assistance in various ways, amongst whom are Prof. G. S. Brady, 



F. R.S., and Rev. T. R. R. Stebbing, F.R.S. ; Dr. G. W. Chaster, of South- 

 port ; J. T. Marshall, Torquay ; Mrs. Robertson, of Millport j and Fred. 



G. Pearcey. My son, Mr. Andrew Scott, prepared the series of drawings 

 necessary for the elucidation of new and obscure species. 



Since the publication of the catalogue of "The Marine Fishes and 

 Invertebrates of Loch Fyne " no additions have been made to the follow- 

 ing groups : — The Fishes, the Tunicata, the Mollusca, the Branchiopoda, 

 the Polyzoa, the Echinoderma, the Actinozoa, the Hydrozoa, and the 

 Spongozoa. 



ADDITIONS TO THE CRUSTACEA OF LOCH FYNE. 



(1) The Schizopoda. 



Erythrops serrata, G. 0. Sars. This species was obtained in Upper 

 Loch Fyne at Stations XIII: and XV. E. serrata was recorded last year 

 for the first time as a member of the Clyde fauna, from specimens obtained 

 in different parts of the seaward portion of the estuary. 



(2) The Isopoda. 



Paramunna Mlohata, G. O. Sars. This is a small species, but very dis- 

 tinct from any other Isopod recorded from the Clyde. The form of the 

 caudal segment, with its strongly toothed lateral margins, and the bilobed 

 front part of the head,«are characteristic. This, which is an addition to 

 the British fauna, was dredged at Otter- Spit during last October by F. G. 

 Pearcey, while at work on board the s.s. Gaiiand. 



(3) The Amphipoda. 



Lilljehorcjia kinahani (Spence Bate). This Amphipod was obtained 

 amongst some dredged material from Otter Spit, Loch Fyne. Though 

 this is apparently the first record of it in Loch Fyne, it has already been 

 recorded for the Clyde by the late Dr. Robertson, of Millport, under 

 Spence Bate's name of Plimdra kinaliani. Lilljeborgia kinahani need not 

 be mistaken for L. pallida (which has also been recorded for the Clyde 

 by Dr. Robertson) ; not only because it is much smaller, but also because 

 of the distinct difference in the form of the metasome segments. 



Podocerus herdmani, Walker. This was obtained in the same gathering 

 as the last, and is apparently not only an addition to the Loch Fyne fauna 

 but also to the Clyde. P. herdmani is distinguished chiefly by the 

 peculiar form of the claw of the posterior gnathopods in the male, and 

 without male specimens it is somewhat difficult to differentiate the species. 

 This Amphipod has been recorded from Norway by Prof. G. 0. Sars, and 

 its British distribution seems to be extensive, having been observed in the 

 Liverpool district, where it was first discovered by A. 0. Walker, the 

 describer of the species, and also in the Firth of Forth. 



Podocerus cumhrensis, Stebbing and Robertson. This Amphipod, though 

 previously reported for the Clyde — viz., from the vicinity of the Clach 

 Rock, C umbrae — has not so far apparently been observed in Loch Fyne.
