THE FAUNA OF THE SALCOMBE ESTUARY. 



worthy feature being the abundance of very large specimens of 



Fhascolosovia : — 



GEPHYREA. 



Phascolosoma vulgare. Large specimens very abundant in a patch, of gravel 

 measuring 10 j-ards by 3 yards. 



POLYCH.ETA. 



Nereis cultrifera. Several. | Arenicola marina. Occasional. 



POLYZOA. 



Loxosoma phascolosomatum. Common, attached to the hinder end of nearly all 

 the specimens of Phascolosoma. 



4. ZOSTERA BANKS AT THE NORTH-EASTERN END 

 OF SALCOMBE HARBOUR. 



The shores exposed at low water at the north-eastern end of Salcombe 

 Harbour consist chiefly of banks of fairly hard muddy sand covered 

 with zostera. Near low-water mark tliere are generally patches of 

 finer and softer mud from which the zostera is absent. Three of these 

 banks were examined carefully, but the fauna on all three is so similar 

 that they may be treated together. These banks are (1) the zostera 

 bank between Snape's Point and Salcombe town ; (2) the zostera bank 

 south of Pil worthy Point at the junction of the Kingsbridge estuary 

 and Southpool Lake; (3) the zostera bank between Ditch End and 

 Southpool Lake, on the south-east shore. 



In the following list the comparative abundance of each species on 

 the different banks is indicated.

3. June 16th, 1900, tide 14 ft. 10 in. ; July loth, 1900, tide 15 ft. 6 in. 



FORAMINIFERA. 



A sample from the surface of the zostera bed south of Pilworthy Point consisted 

 of a very fine sand with extremely small particles mixed with it. Thirty-five 

 Foraminifera were found in 13 c.grms. Of these seven were not identified, but 

 all were probably species as under. Of those identified : —

 Textularia agglutinans 

 Nonionina depressula 

 Lagena striata
