Spio filicornis Fabiicius : Mchitosh, Mon. Brit. Ann. III. 1, 1915, p. 172. 

 Plymouth. In fine, clean sand at Wembury Bay, at low tide. 

 The head of the living worm was conical, the point being used 

 in attempts to burrow. The point could be bent downwards into 

 the shape of a hook. 

 Pygospio elegans Claparede : Mcintosh, Mon. Brit. Ann. III. 1, 1915, 

 p. 189. 



Plymouth. Forming tubes in very fine sand near the mouth of 

 the Yealm Eiver. 



Breeding : March. 



ExMOUTH. In the clean hard sand of the estuary. Not found 

 on the more exposed Pole Sands (Joum. M.B.A., vol. 6, 1902, p. 320). 



Teignmouth. Abundant in sand below Shaldon Bridge. 

 Pygospio seticornis (Oersted) : Mesnil, Bull. Sci. France et Belg. 

 XXX. 1897, p. 85 ; Cunningham and Ramage, Trans. Roy. Soc. 

 Edinburgh, XXXIII. 1888, p. 640. 



Salcombe, Abundant on the shore under the Marine Hotel, 

 forming long, slender tubes or galleries of mucus covered with sand 

 grains (Journ. M.B.A., voL 6, 1900, p. 194). 



Exmouth. In clean hard sand in the estuary (Journ. M.B.A., voL 6, 

 1902, p. 320). 



The gills on the second setigerous segment are still very con- 

 spicuous and unmistakable in some of the preserved specimens which 

 have recently been re-examined. Mesnil (loc. cit.) thinks that this 

 form is not the Sfio seticornis of Fabricius. Excepting for the 

 presence of the gills on the second setigerous segment the species 

 very closely resembles Pygospio elegans of Claparede.
