 Loch Fyne. 



Halosydna gelatinosa, Sars. — This was taken on the east side of Upper 

 Loch Fyne, and on the shore at low water (M.). 



Polynoe squamata (Johnston). — At Minard ; on both sides of Upper 

 Loch Fyne, in 10 to 30 fathoms • and between tide-marks (M.). 



Polynoe, sp. — A species of Polynoe, not identified, was obtained at 

 Minard ; and on both sides, as well as in the centre and near the head of 

 the Loch, in 10 to 35 fathoms ; it was also found on the shore between 

 tide-marks (M.). 



Aphrodite aculeata (Linne). — At Minard ; and on the east side and in 

 the centre of Upper Loch Fyne, in 15 to 70 fathoms, as well as near the 

 head of the Loch (M.). East Loch Tarbert and adjacent parts of Lower 

 Loch Fyne, not rare. 



Hermione hystrix Savigny ( = Aphrodite hystrix). — This species 

 appears to be more restricted in its distribution than the last, and confined 

 to deeper water ; it was obtained in Upper Loch Fyne, in the deep water 

 of the centre — 65 to 70 fathoms (M.). 



Gephyrea. 



Sipunculus bernhardus was obtained at Minard, in about 10 fathoms 

 (M.). 



if) Phascolosoma strombi (Mont.). — A species of Sipunculus, which 

 was probably a Phascolosoma, was obtained at Minard, and also in the

 shells of Dentalium (M.). 



Celetognatha. 



Sagitta bipunctata, Quoy and Gainard, appeared to be generally distri- 

 buted all over the Loch. 



Nemertea. 



Lineus marinus (Mont.) is occasionally obtained at the roots of tangle 

 and other sea-weeds, specimens many yards in length being sometimes 

 observed. 



Turbellaria. 



Planaria, sp. — Specimens of a Planaria (probably Planaria littoralis) 

 are occasionally observed in Loch Fyne ; but the Planarians, as well 

 as the other groups of Vermes, require further study ; and when that is 

 done considerable additions will uo doubt be made to the preceding list.

The Catalogue of the British Echinoderms in the British Museum, 

 by Prof. Jeffrey Bell, is followed as to the arrangement and names in 

 this list.
