Mr Taylor, malacology in Scotland is not "done to death," to say 

 the least. There are only some three or four counties from which 

 reports were sent in, and these of the most meagre description. 

 In our own district there have already been good workers, Dr 

 Buchanan White, Mr Rimmer, Mr R. Service, and others. To 

 Dr B. White, I believe, we owe the first actual record, printed 

 fifteen years ago (Sept., 1870) in " M'Diarmid's Handbook of 

 Southwick and Colvend," for which Rev. J. Fraser wrote tlie 

 botanical chapter. In the list of L. and F. W. Mollusks 

 there given Dr W^hite records thirty - six species, adding 

 " that probably more than a dozen other species inhabit the 

 district." His record contains — Arion ater, L. agrestis, and 

 marginatus (three out of the fourteen slugs known as Britisli), 

 S. putris, V, pelhccida, seven species of Zonites, eight Helices, 

 Z. luhrica, C. rugosa, B. perversa, P. cylindracea and Anglica, 

 V. edentula, only two Planorbes, albus and contortus, Ph. fonti- 

 nalis, Lirnncea lacustris, truncatula, and palustris, A. Jluviatilis, 

 tlie decollated form of B. tentaculata, V. jnscinalis, and S2)h. 

 corneum, with the yellow variety, Jlavescens. 



In this list there are seven species which I have not yet come 

 upon, while additionally to it I have found Pisidium fontinale and 

 pusillwrn, M. margaritifer, Valvata cristata, Planorbus nautileus, 

 and spirorbis, Ancylus lacustris, Zonites purus, H. aspersa, 

 concinna, and Carycldum 'ininivmm. 



In addition to all these, I subjoin the following names, which 

 have been recorded for the district by other workers : — Pisidiiom 

 amnicum and nitidum ; Anodonta cygncea ; Planorbis nitidus 

 and comjylanaius ; Lirnncea stagnalis ; Succinea oblonga ; Helix 

 lamellata, sericea, and ericetorum ; Btilimiis acutus and obscu,rus; 

 Pupa ringens and marginata ; Vertigo pygmcea and pusilla ; 

 Cochlicopa tridens and Acme lineata. 



I am unable to mention localities for the above nineteen 

 mollusks, since their names appear simply thus towards the close 

 of Maxwell's " Guide to the Stewartry " — in a list compiled by 

 Mr Service from various sources. There are, therefore, just 60 

 species recorded of land and fresh water mollusks belonging to 

 the S.W. of Scotland. Any attempt to allocate them to the 

 three counties or to compile a census from them is unhappily at 

 present impossible. This must be left to time and to our own 

 care and interest in the subject. A few words respecting the 

 comparative or rather relative rarity and abundance of tlie species
