latter form has the tentacle at its anterior nostril simply bifid at its extremity :

The shanny appears to be distributed almost everywhere in pools between tide 

 marks around the British coast, and has been recorded from Banffshire (Edward) : 

 Aberdeen (Sim), here I procured an example, and several likewise from St. 

 Andrew's : Moray Firth : common in the Firth of Forth (Parnell) : Berwickshire 

 (Johnston) : Yorkshire, resident and common in rock pools from Redcar to 

 Flamborough (Fauna of Yorkshire, p. 113) : Norfolk, among stones at low 

 tide (Gurney), abundant at Weymouth (Gosse), and very common all along 

 the south coast, especially in Devonshire and Cornwall. Pennant found it to be 

 common in Anglesea, but Donovan observed that in the thirty years which had 

 elapsed since Pennant's remarks were published he found it had disappeared 

 (except in one spot), and this he attributed to the tang having been almost 

 eradicated for the use of glass-makers, &c. : also Pembrokeshire. 



In Ireland it is common around the coast (Thompson). 



It attains to at least 6 inches in length.
