318 THE FAUNA OF THE EXE ESTUARY. 



GEPHYREA. 



Phascolosoma vulgare, BlainviUc. Common in a small patch of 

 muddy sand with large gravel, at low-water mark, on the east side of 

 the stream draining Greenland Lake (sta. 12). Many of the specimens 

 had colonies of Loxosoma phascoIosomatiDn growing on the posterior 

 end. As at Salcombe, the ground where this species was found was 

 very limited in size, but the number of specimens obtained was 

 considerable. The nature of the soil, however, in which the species 

 lived at Exmouth differed considerably from the stiff clay-gravel lying 

 on hard clay in which it was found at Salcombe. 



TURBELLARIA. 



Leptoplana tremellaris {0. F. Mailer). One dredged on the 

 sponge ground off the Clock Tower (sta. 14b), and one on the mussel 

 bank (sta. 14c). 



POLYCH^TA.* 



[Nomenclature : de Saint-Joseph, " Les Anuelides Polychetes des Cotes de Dinard," Ann. 

 Sci. Nat. Zoologie, 1887-95 ; " Les Annelides Polychetes des Cotes de France (Mauche 

 et Ocean)," ditto, 1898.] 



EuPHROSYNE foliosa, Audouin et Edwards. One specimen only 

 dredged on the sponge ground (sta. 14b). 



Lepidoxotus clava, Montagu. Not uncommon on the shore at Or- 

 combe Eocks. 



EvARNE IMPAR, Jolinstoii. One specimen was found hiding under 

 a tile on the sand west of the mouth of Salthouse Lake (sta. 10). 



Sthenelais boa, Johnston. One specimen was dredged on the 

 mussel bed in the channel below Checkstone Ledge (sta. 14c). It was 

 never met with on the shore between tide-marks, as at Salcombe and 

 Plymouth. 



Marphysa sanguinea, Montagu. One specimen only, from Orcombe 

 Eocks. 



:N'ereis culteifera, Grule. Only met with at Orcombe Eocks, quite 

 at the mouth of the estuary, and there but one specimen was found. 

 This is noteworthy, as N. cultrifera is one of the commonest species 

 found on the shore both in Plymouth Sound and in the Salcombe 

 estuary. 



Nereis pelagica, Linn. A few specimens amongst the masses of 

 sponge {Halichondria panicea) dredged in the main channel below the 

 pier (sta. 14b). 



Nereis fucata, Savigny. Found once in a shell inhabited by 

 Eupagurus Bernhardus taken at Orcombe Eocks.
