ll. Description of the Cydippe Pomiformis mihi, (Beroe Ovatus, Flem.) with 

 Notice of an apparent^ undescrihed Species of Bolina, also found on the 

 Coast of Ireland. By Robert Patterson, Esq., Member of the Natural 

 History Society of Belfast.

It is proposed to give in the present paper some account of the appearance, 

 organization, economy, and habits of a Beroe, not uncommon on our Irish coast, 

 in the hope that such details may prove interesting with regard to the species 

 described, and may be of some value as illustrative of the family to which it 

 belongs. 



These observations were commenced in the month of May, 1835, at which 

 time I resided in the immediate vicinity of the small sea-port town of Larne, in 

 the County of Antrim. My lodging was situated on the small peninsula termed 

 the Corran,* and nearly midway between the two stations, whence ferry-boats 

 ply to the opposite peninsula of Island Magee. Through the narrow channel, 

 across which these boats are continually plying, the tide runs with great rapidity 

 into Lame Lough. Hence I had, by means of the ferry-boats, an easy mode of 

 taking, at all hours during the day, the small Medusce and Crustacea, which the 

 flow of the tide placed within reach of a small canvass towing net. As the 

 Beroes could thus with facility be procured, and were to me highly attractive, 

 my sitting-room, for between two and three weeks, was never without some of 

 them. They were kept in glass jars, the water in which was changed twice 

 each day. The particulars which I then observed, were published in the Edin- 

 burgh New Philosophical Journal for January, 1836, and reasons adduced for 

 regarding the species as distinct from the Beroe Pileus, the only tentaculated 

 Beroe then regarded as British. 



* This word in the Irish language signifies " Reaping Hook," to which implement the little 

 peninsula has a striking resemblance in form.
