Portmarnock Strand. 



Howth, south shore, 6, x, '07. 



This species, which usually lives between tide-marks, forms tubes of 

 sand-gi-ains, which are massed together like honey-comb. On the strand 

 between Portmarnock and Malahide they can be seen in great masses, 

 covering the rocks, and forming quite a conspicuous feature in the land- 

 scape. 



General Distribution. — British Isles ; English Channel ; MecUterranean. 



Sabellaria spinulosa, Leuckart. 



1867. Mabngren. Tom. cit., p. 102. 



2 miles south-east of Bailey Light, l.S, ra, '07. Dredge, 13-18 fms. 



Shennick's Island, Skerries. At low-water. 



This species usually fi-equents the deeper waters near the coast. It is 

 however, occasionally found between tide-marks, as at Skerries. It was 

 di'edged in large quantities in the Bay. The interlacing tubes form masses 

 on stones and old shells ; but their arrangement is not so regular as those of 

 S. alveolata. 



General Distribution. — British Isles ; North Sea ; English Channel.
