in thousands after some winter storms. It is also a common 

 diet of the cod and haddock. 



Fam. 4. Polynoidae. 



Genus Lepidonotus, Leach. 



Lepidonotus squamatus, L. ; Mgrn. op. cit. p. 4. 



Frequent in deep water, under stones in pools between tide- 

 marks, on the West Sands after storms, and in the stomachs 

 of cod and haddock.

 Nychia cirrosa, Pallas ; Mgrn. op. cit. p. 5. 



Occasionally in deep water, and on the West Sands after 

 storms.

Occasionally in debris of the fishing-boats. It is distin- 

 guished by its greyish scales mottled with black, by the dark 

 spots at the bases of the feet, the mottling of the dorsum 

 beneath the scales, and by the position of the eyes (the posterior 

 pair only being visible from the dorsum). The dorsal bristles 

 have a short clear portion at the tip ; the ventral are long, 

 much tapered and minutely bifid superiorly, while the inferior 

 have shorter and stouter tips, more evidently bifid. 



Genus Haemothoe, Kinberg. 

 Harmothoe imbricata, L. ; Mgrn. op. cit. p. 9. 



Very abundant under stones between tide-marks, and ranging 

 to deep water.

 general appearance and processes. Scales fourteen to fifteen

 beyond the bristles ; serrations of the dorsal bristles continued 

 to the tip ; ventral bristles boldly bifid, and with rather broad 

 tips.
