1903. Bromehead, C. N. : List of Mollusca found in the Neighbour- 

 hood of Marlborough. Report of the Marlborough College 

 Natural History Society for the year ending Xmas, 1903 

 Enumerates thirty-six species and eight varieties. 



Note on Vitrina elongata Drap. — On several occasions during 1904-05 I 

 took specimens of the above, and was greatly struck by its peculiarly flat shell, and 

 the size of the snail as compared with its shell. I took it to be a variety of 

 V. pellucida, but had never seen any in the least like it before. I sent some 

 specimens for exhibition at the meeting of the Conchological Society held Sept. 14, 

 1904, and they were recorded in \hs. Journal as V. pellucida var. dtpresshiscula. 

 In 1906 I sent my collection to Mr. J. W. Taylor, and suggested that he might use 

 one of my specimens for an illustration in his Monograph if he had not a better 

 one, as I considered them so very abnormal and striking ; but when writing on 

 the subject of Vitritice he had not come across the specimens in my collection. It 

 was only in June or July last that he found the specimens, and recognised them as 

 a new British species. On Nov. 6th I visited the demesne at Collon, co. Louth, 

 the only locality where I have found them, and where they are very abundant 

 among fallen beech leaves. The soil is a cold wet clay. The snail is easily 

 observed when you are looking specially for it and have once seen it alive. I 

 procured a number of specimens in about one-hour-and-a-half, all of which I have 

 sent to various people for observation and dissection. — P. H. Grierson {Read

Assemania grayana Leach, in Suffolk. — In June last year, whilst examining 

 siftings from the rejectamenta of the River Aide, at Aldeburgh, I obtained a few 

 examples of Assemania grayana. This species is an extremely local shell, being 

 only known from the banks of the Thames below Erith, Cuxton, River Med way, 

 the Stour at Sandwich, the Blackwater and Colne in Essex, whilst there are only two 

 records for the form outside England, viz., Ribe, Denmark, where the species was 

 detected by Dr. A. C. Johansen, and an old record for Belgium, which may be 

 incorrect. It has been recorded from Cleethorpes, Lincolnshire, F. M. Burton 

 (^Naturalist, 1893, p. 255), but the identification has been doubted by Mr. H. Wallis 

 Kew [Naturalist, 1902, p. 269). I am indebted to Mr. A. S. Kennard, F. G.S., 

 for verifying the identification of the shells as well as for the above facts concerning 

 the distribution of the species. Since writing the above I have found a single 

 specimen at the mouth of the River Orwell, and Mr. Kennard has met with it in 

 rejectamenta from the River Blyth, at Blythburgh. This latter find is very interest- 

 ing, as it extends the range of the species still further northwards. — A. Mayfield 

 (Read before the Society, May 8th, 1907). 



Paludestrina jenkinsi in Middlesex.— On October 5th we found a flourish- 

 ing colony oi Paludestrina Jenkinsi in a small swamp close to one of the branches 

 of the river Colne, near Uxbridge. It is not clear how they were introduced there, 

 as the stream in question is not used as a canal. So far as we know this is a new 

 record for the district. — G. D. H. Carpenter and J. E. Cooper {Read before the 

 Society, Nov. 13th, 1907).
