Many important collections passed through Mr. Sowerhy's hands, 

 including those of Lombe-Taylor, Dr. Hungerford, Dr. Prevost, Mr. 

 Keen of Liverpool, A. Gassies, B. C. Thomas, and during his partner- 

 ship with the writer, those of (leneral Tripe, Lord Ashbrook, Dr. 

 Cox, Admiral van Rees, Admiral Harry Keppell, Mrs. Fitzgerald, 

 L. Bouge, J. B. S. Grateloup (part only), Colonel Parry, A. Denans, 

 Miers, Granger, Guestier, J- S. Gibbons, Carl Biilow, and E. L. 

 Layard. 



A member of this Society since 1886, and a Vice-President in 1889, 

 Mr. Sowerby also served on the Council of this Society as well as on 

 that of the Malacological Society of London, of which he was an 

 original member. He was elected a fellow of the Linnean Society in 

 1888. 



Our late member possessed a most genial and generous nature, 

 which endeared him to his many friends. A man of strong character, 

 he endeavoured to live up to the religious principles he professed. 



Pisidium tenuilineatum Stelfox in the Thames.— A gathering of Pisidia that 

 I made on September 4th, 1920, in the Thames at Streatley, where the river 

 divides Berkshire from Oxon, inchided a single hut quite characteristic example of 

 Pisidunn tenuilincatuui. The Pisidia associated with it were the same, although 

 the proportions in which the individual species occurred were different, as those 

 found in the original localitj' for P. teniiiUneatum^ the Grand Junction Canal at 

 Cheddington and Marsworth, Bucks., i.e., P. amniaem, casertantttn, nitidnm, 

 stibtriincatiiin, Jiensloivanitin, suphiiiiii, SLXiA faj-viihwi. — CHARLES Oldham {Read 

 before the Society, December 8th, 1920). 



Pisidium parvulum Ciessin in Cheshire. — A gathering of Pisidia which I 

 made in the Shropshire Union Canal at Beeston Castle on April 6th, 1920, 

 included a single specimen of this species, and on a subsequent visit on July 31st I 

 secured two more. The Pisidia associated with it were amniaiin, casertanwii, 

 subfruneatum, supimim, henslowanum, and nitiduin var. crassa. P. parviiluni is, 

 perhaps, not so rare in this country as has been supposed, for during the past few 

 years, I have taken it alive in Middlesex, Surrey, Herts, Bucks., Berks., Oxon, 

 Beds., Northants, Wilts., and Worcestershire, and fossil shells in holocene deposits 

 in Herts, and Beds. It probably often escapes notice owing to its diminutive size 

 and the fact that the coarse-meshed collecting scoops in general use will not retain 

 it. — Charles Oldham (Read before tlic Society, September 8th, 1920). 



Limax cinereo-niger in Kent. — At the Annual General Meeting of the 

 Society I showed a specimen of this slug as a new census record, Mr. Charles 

 Oldham pointed out that it was an unrecorded vaiiety, the ground colour being of 

 a delicate pearly grey, including the keel-line, while the body-markings, which 

 correspond with those of the var. punctata of Lessona, are deep ash-coloured with 

 black lateral markings. This variety is not uncommon at Hucking, Kent, where 

 it co-exists with the type and the var. punctata. — H. C. Huggins {.Read before the 

 Society, November lOth, 1920).
