and other places. Later he became interested in Microscopy and 

 recent Conchology, and although a busy man, devoted much of his 

 spare time to these subjects. Combining the two with his skill in 

 photography, he eventually took up as his speciality the study of the 

 moUuscan radulse, more particularly those of the HxalinUz, a group of 

 which he was very fond, and not only prepared them as microscopic 

 objects in his own inimitable way, but made exquisite photomicro- 

 graphs of them as well, from which he produced beautiful lantern 

 slides. His study of this subject brought him into touch with the 

 most expert students of the radulfe both at home and abroad. He 

 was in continuous correspondence with the Rev. Prof. H. M. Gwatkin, 

 the best exponent of the subject in this country, and with the 

 Smithsonian Institution, and leading American and Japanese 

 conchologists. 



He was also keenly interested in the general anatomy of the genera 

 in which he specialized,, more particularly that of the reproductive 

 organs. I believe he was the Jirst to note and call attention to the 

 curious, slipper-shaped, internal calcareous organ in Helicella barbara 

 {Bulimus acutus), and carefully studied its functions. He did not 

 much care for or collect marine shells. The British non-marine 

 mollusca had first place in his regard, but he took great interest in 

 certain groups of exotic terrestrial shells, and in the problems of 

 insular faunas, notably those of New Zealand, Hawaii, Madeira and 

 Trinidad. He was especially proud of a long series of Parypliatita 

 hochstetteri from New Zealand, in all stages of growth from the egg 

 upwards. Knowing my own partiality for the calcareous eggs of the 

 mollusca he very generously handed over to me his set of eggs and 

 embryo shells of this rare species, which, needless to say, are now 

 amongst the most treasured specimens in my collection. As a matter 

 of fact he was always generously disposed towards anyone working at 

 particular groups, and ever ready to help young beginners when he 

 had duplicates to spare. Quite recently he enriched the Museum of 

 the Manchester Grammar School by a munificent gift of shells. 



He was largely instrumental in inducing the late Mr. R. D. Darbi- 

 shire to acquire the large collection of Lifu mollusca formed by his 

 friends the Rev. James and Mrs. Hadfield. This collection, after 

 being worked out, and the results published in our Journal^ finally 

 found a fitting resting place in the Manchester Museum. Of the 

 numerous new forms described from this collection, one species, 

 Syrtiola mossiana Melvill and Standen, was named in his honour. 



The following are the most important papers written by Mr. Moss, 

 either singly or in collaboration with others : —
