The new species is very similar in general to S. capensis^ but is 

 much longer and narrower, and lacks the well-developed internal cone. 

 As compared with 6". elofigata^ it is broader and thinner, but re- 

 sembles it in the development of the outer cone. It is to be hoped 

 that Mr. Burnup may be fortunate enough to procure complete 

 examples of this interesting form. 



Some Results of a Flood in North Ireland.— "'Tis an ill wind that blows 

 nobody good " is a trite saying, and the hurricane on the morning of February 27th 

 last that left a zone of devastation across Ireland and England, in breaking through 

 the embankments that guard from the sea large areas of reclaimed land in North 

 Derry, let the flood waters of the Burnfoot River into one intake. With this flood 

 came large masses of fine vegetable debris swept from the banks of the river and 

 this with the debris, many tons in weight, from the flooded area, over a mile square, 

 was stranded on the inner slopes of the embankment between the inner and outer 

 breaks and at the mouth of the river also, where it covered an area of over 200 

 square feet. Feeling sure this would have small land shells in it, I examined it at 

 once and finding plenty of Hyalinia crystallina and Helix pidchella on the surface 

 I soon had a large bag full of the wet mass draining off. Bringing this home I 

 turned it into a large tub of fresh water to get rid of the salt, for the sea had also 

 broken into the intake after the river-water had softened the inner slopes. On 

 pressing a wire sieve on the mass the finer part came to the surface and was 

 skimmed off, and this operation was repeated till most of the portion containing the 

 small shells had floated through. This I found a very much quicker way than the 

 usual one of drying all the mass, as the remainder could now be washed through the 

 sieve under the tap and all the finer part drained in a gauze sieve and dried ; this I 

 do on old thick photo-blotting boards. When dry I sifted a little of it into several 

 grades and examined for shells, the following species being present. I have plea- 

 sure in sending the remainder not examined for distribution among those members 

 who care to look through it. The farms are submerged at high tide from two to 

 about eight feet, and great masses of the debris are all over the embankment and 

 likely to be available for collectors for months to come. List of species : —
