THE FAUNA OF THE SALCOMBE ESTUARY. 207 



Tellina solidula, Pulteney. Shells of this species were common 

 on the mud near Kingsbridge, One or two living ones were found in 

 the muddy gravel between the zostera and shore, near Ditch End, 

 buried three or four inches below the surface. 



Syndosmya alba {Wood). Several living specimens were dredged in 

 the channel off Tosnos Point. 



SCROBICULARIA PIPERATA (Gmelin). This species was not uncommon 

 in the mud just to the south of Snape's Point, and also in the gravel to 

 the nortli of Pilworthy Point. They appear to be gregarious in habit, 

 four or five occurring together in a small patch of suitable gravel or 

 mud. Single ones were found in the creek below the Piectory (South- 

 pool Lake) in gravel, south-east of Pilworthy Point, and in the gravel 

 under the Marine Hotel. At Plymouth I have found them only in the 

 fine mud in St. John's Lake, a branch of the Hamoaze, where they are 

 common, occurring a dozen or so in a patch of ground a yard square. 



Mactr-a. solida, Linnceus. Fairly common in the clean shell-gravel 

 in tlie " Bag " off Snape's Point. Shells were very common in North 

 and South Sand Bays. One or two specimens were obtained on the 

 Bar. When dredging in the latter locality on October 2nd, 1896, 

 large numbers of this species were obtained. [E. J. A.] 



LuTRARiA ELLIPTICA, Lamarck. This bivalve was found most com- 

 monly on a sand and zostera bank off Millbay, which was only un- 

 covered at low water. It was also not uncommon on the sand and 

 zostera banks between Millbay and the Ferry House. Single specimens 

 were found in the sand below Gazebo, in gravel on the south-east and 

 in mud on the north-east shore of the Salstone. They were generally 

 found buried a foot or more below the surface, their siphons being 

 visible before the tide left them. When first uncovered by the tide the 

 siphons were contracted, and the holes left by them generally filled up 

 with sand, and it was not till nearly low-water that they were 

 again extended to the surface. After making the aperture afresh the 

 siphons were withdrawn two or three inches. The hole at the surface 

 is usually oval in shape, although one was found almost exactly like 

 that of Solen marginatus (see above). 



One Zutraria, which we dredged in the channel of Salcombe 

 Harbour, was being eaten by an Octopus, one valve of the shell being 

 broken (? by the dredge). A Lutraria and an Octopus were trawled 

 under similar circumstances in Cawsand Bay, Plymouth, on October 1st, 

 1900, but in this case both valves of the Lutraria were intact. 



Tapes decussata {Linnceus). Several living specimens were found 

 in muddy gravel to the north of Pilworthy Point, and also in the bight 

 below the Eectory (Southpool Lake). They were generally buried a 

 few inches deep in the gravel.
