THE FAUiVA OF THE EXE ESTUARY. 319 



Nereis diversicolor, 0. F. MuUcr. Very common in the upper 

 parts of the estuary, especially in the mud at Greeulands (sta. 1), at the 

 mouth of Keun Eiver (sta. 3), below Powderham (sta. 4), and on the 

 mud north of Salthouse Lake (sta. 11). A few were taken east, of 

 Powderham mussel beds (sta. 2) and in muddy sand at Cocklesaud 

 (sta. 13). As is usually the case, this species is most abundant where 

 the water is of low density. 



Nereis irrorata {Malmgren). One specimen only outside the estuary 

 at Orcombe Eocks. 



Nereis longissima, Johnston. One specimen on Bullhill Bank, and 

 one on the mud north of Salthouse Lake (sta. 11). The rarity of this 

 species is noteworthy, as it was abundant in fine muddy sand in the 

 upper parts of Salcombe estuary. 



Nephthys C-i:cA (Fahricius). Several large specimens from Bull- 

 hill Bank (sta. 9). 



Xefhthys Hombergii, Audouin et Edicarch. As at Salcombe, this 

 species was commonly found in sand and muddy sand all over the 

 estuary. "Where the ground became very muddy it disappeared. 



Nephthys cirrosa. Elders, was found in considerable numbers on 

 grounds where the soil was fine clean sand, but did not occur in 

 any other localities. It appears to be only able to flourish in ground 

 of this nature, and is therefore much more restricted in distribution 

 than KejjJiflnjs Homhergii. Nephtliys cirrosa was common on Polesands, 

 on the sand of Bullhill Bank (sta. 9), and on the sand above Starcross 

 (sta. 5); and one specimen is recorded from Cocklesaud (sta. 13). 



Glycera convoluta, Kcfcrstein, was occasionally found on Bullhill 

 Bank (sta. 9) and on the gravel between Powderham and Starcross 



(sta. 4). 



Phyllodoce (.? macidata, Linn.). A Phyllodoce, which appears to 

 be referable to this species as described by Johnston {British Museum 

 Catcdogue, 1865), was taken on the sandy ground between Starcross 

 and Cockwood (sta. 8). 



Phyllodoce teres, Malmgren. Found in fine clean sand on two 

 grounds in the upper part of the estuary, viz. the sand bank above 

 Starcross (sta. 5) and the sand west of Salthouse Lake (sta. 10). 

 It is also recorded from the gravel between Powderham and Starcross 

 (sta. 4), though the exact nature of the ground where the two specimens 

 were taken was not noted. I found this species also at Teignmouth in 

 clean sand, which appears to be its normal habitat (cf. Malmgren, 

 Nordiska Hafs. Annulater, 1865, p. 97). 



Eteone FUaiLLA, Oersted (nee Malmgren), was found several times
