THE FAUNA OF THE SALCOMBE ESTUATIY. 189 



TURBELLARIA. 



PROSTHECERyEUS viTTATUS {Moiitagu). Another species first described 

 by Montagu from this locality. We found several specimens on the 

 shore at a 16-ft. tide at the Salstone. Montagu's specimens were also 

 obtained from the shore at Salstone {Trans. Linn. Soc. vol. xi., 1807). 



Prosthiostomum, sp. Dredged in the channel between Salstone and 

 Snape's Point. Agrees closely with one previously taken at Plymouth 

 by Mr. Garstang. Both are remarkably narrow and elongated, and are 

 referable almost certainly to F. sipJmnculus, Delle Chiaje ; but further 

 observations on the living animal are needed to remove all doubt. This 

 is the first record of the genus in British waters. [W. G.] 



GEPHYREA.* 



Phascolosoma vulgare, Blainville. Large specimens of this species 

 were numerous in the Kingsbridge estuary, in the bay immediately to 

 the north of Pilworthy Point. At the north end of this bay, 40 to 50 

 yards south of the first reef of rocks, a patch of ground was found, 

 measuring about 10 yards by 3 yards, where two or three of these large 

 specimens were found in each spadeful of the soil. The ground was 

 composed of stiff clay -gravel, lying on hard clay which passed quickly 

 into soft rock. The species was also abundant, but the specimens were 

 of smaller size, on the eastern shore of Salcombe Harbour, a little to 

 the south of Ditch End, where the ground is composed of hard muddy 

 gravel. One specimen was obtained on the same side of the harbour 

 near Millbay. 



Phascolosoma pellucidum, Keferstein. This species was much more 

 widely distributed than the preceding. It was very common in the 

 zostera banks on the east side of Salcombe Harbour between Millbay 

 and Ferry House, as well as on the western side under the Marine 

 Hotel. It was also taken on the eastern shore from the Perry House to 

 Ditch End, but was here less common than P. vidgare. Single specimens 

 were taken on the zostera banks at the north-east end of Salcombe 

 Harbour, and it was not uncommon on both the western and south- 

 eastern shores of the Salstone, where the ground is hard. 



Phascolion strombi {Montagu). One specimen in a shell of Turritdla 

 communis, from the channel between Snape's Point and the mouth of 

 the harbour. The specimen was identified by Mr. Todd. 



* The two species of Phascolosoma were identified by Mr. A. E. Shitley.
