DISTRIBUTION OF SPECIES. 



•fEURYTHOE BOREALIS, SarS. 



This species has been recorded by Mcintosh from under a stone in a 

 tide pool at Herm. This author regards it as rare in British waters, but 

 Benham (3) remarks that specimens six inches long occur all round 

 the British area. Taking the size of the animal into consideration, it is 

 doubtful if the two authors refer to the same species.

*EUPHR0SYNE FOLIOSA, Audouin and Edwards. 



A species which is by no means uncommon. Its colour is some shade 

 of orange-red, but this has something of a greyish character in many 

 specimens. Those taken from Plymouth Sound are often partially 

 concealed by a covering of flocculent detrital matter. The animal 

 occurs in the holes of rocks and stones brought up by the dredge ; it 

 has also been found on the fine gravel of Ground XIV (1) in the 

 neighbourhood of the Eddystone. 



Of the numerous species of Polychtetes described by Mcintosh in his 

 recent Monograph (20) a large number are noted as being deep-water 

 forms in the north, but as their range of distribution passes to the south, 

 so they make their home in shallower or even tidal waters. This species 

 is a case in point, but I have never met with it in tidal waters. 



Pruvot:]: (29) records it from the Fucus zone, the Himanthalia zone 

 to the gravel of the base of his littoral zone.
