The specimens of N. longissima obtained at Salcombe were generally 

 of a perfectly uniform light shade, which was nearly jflesh colour. 

 One specimen, however, from the western side of the Salstone was 

 very brilliantly coloured. The general ground tint was a purple-grey, 

 and this was covered in patches with a bright chrome-yellow pigment. 

 At the anterior end of the dorsal surface the yellow patches were found 

 covering each side of every segment, leaving a central patch of the 

 purple-grey ground colour between. Behind the first 50 or 60 segments 

 the yellow patches were scattered irregularly. On the ventral surface 

 the anterior segments were almost covered with the yellow, and behind 

 this a median line of yellow extended backwards for some distance. 



Nereis diversicoloe, 0. F. Midler. This worm was numerous only 

 in a small gully traversed by a stream of fresh water, which runs into 

 Southpool Lake just below the Eectory (see Chart). Occasional 

 specimens were found in other parts of the harbour. The distribution 

 of this species at Plymouth shows it to be an essentially brackish-water 

 animal, which is in agreement with what we found at Salcombe. 



Nereis fucata, Savigny. The normal habit of the worm is to live 

 in the upper coils of a shell inhabited by a hermit-crab. We did not 

 specially seek for it when at Salcombe, and the single specimen recorded 

 was given me by some children who were catching hermit-crabs when 

 we were collecting on Millbay Sands. 



Phyllodoce. Two or three undetermined species of Phyllodoce were 

 common in dredge material, especially in that from the Kingsbridge 

 estuary. 



EuLALiA PUNCTIFERA, Gruhc, was identified from material dredged in 

 the channel between Salstone and Snape's Point. 



EuLALiA viRiDis {MulUr) was also found in dredge material obtained 

 between Salstone and Snape's Point. 



Nephthys hombergii, Audouin et Edwards, must be regarded as one 

 of the commonest, if not the commonest, shore Polychaete in Salcombe 

 estuary. It is met with on grounds of all kinds, excepting possibly 

 the very finest mud, and seems about equally distributed from Garston 

 Point to the mouth of the harbour. On the clean sand at Millbay 

 numerous very small specimens were found, which in some places were 

 almost the only living creatures in the sand. 



Nephthys caeca {Fabricius) was found only on the banks near the 

 mouth of the harbour, being most numerous on the eastern side. The 

 specimens were generally of large size. The habit of the species seems 

 to resemble that of N. Homlcrgii, although in this case the local 

 distribution is very different. The two species {N. caeca and N. Horn-
