 neighbourhood of POET EEIN, ISLE OF MAN.

In the first volume of the "Fauna of Liverpool Bay," 

 several species of Nemertines were recorded for the dis- 

 trict, but since that time no additions have been made to 

 this division of the Fauna of the Irish Sea. In the 

 present list are noted those genera and species which 

 have come under our notice, during the spring and summer 

 of this year, at Port Erin and in its immediate neighbour- 

 hood. The list is far from being a complete one, and 

 there is no doubt that this interesting class of worms will 

 be found to be well represented on the Manx coast. 



The habitat of the group is varied. Some, like Nemertes 

 neesii, are found under stones at high tide mark, others 

 only at mid and low tide among the tufts of Corallina 

 officinalis, while others again love the deeper waters and 

 are only captured by means of the dredge. On the east 

 shore of the Calf Island is a group of rocks (" The Clets,") 

 forming at low water an excellent hunting ground for 

 many marine animals, and especially in respect to the 

 Nemertines, which abound there in the masses of Grisia 

 and Tubularia. 



Owing to their great power of contractility, these worms 

 are difficult to kill in an extended and normal condition. 

 Authors have recommended various methods, such as the 

 use of corrosive sublimate or chloral hydrate, but the 

 results obtained are very uncertain. A one per cent solu- 

 tion of cocain, however, answers well in most cases, and
