authority on the subject of British shells. In 1886 he published 

 a List of British J^Iollu.sca and Brachiopoda, which was accepted 

 as the standard catalogue until superseded in 190U by the official 

 list of the Conchological Society of Great Britain and Ireland. 

 His appointment by that society as one of the three referees for 

 marine shells may be regarded as iiidicating the high estimation 

 in which his attainments as a conchologist were held. 



In the department of Scottish Topographical Botany, particu- 

 larly in the investigations for working out the flora of the 

 Watsonian vice-counties, his important researches — carried on 

 chiefly in the West of Scotland, but occasionally extended to 

 Orkney and other remoter regions — have led to the acquisition of 

 much valuable information relating to plant-distribution, including 

 many interesting records of the occurrence of species in districts 

 where they were not previously known to exist In the course 

 of this work he entered into correspondence with the recognised 

 authorities in various departments of botany, to whom he was 

 likewise accustomed to submit specimens of the plants upon 

 which his records were based, thus greatly enhancing the value 

 of the information due to his individual researches. He also 

 formed an herbarium of British Flowering-plants and Ferns, 

 upon which he expended so much careful labour as to render it 

 one of the finest in the country. 



After returning to Glasgow from India, he became connected 

 with various scientific institutions. One of the earliest to be 

 joined was the Linnean Society, of which he was a Fellow. He 

 was elected a member of the Natural History Society of Glasgow 

 on 13th September, 1881, and a Fellow of the Botanical Society 

 of Edinburgh on 11th February, 1886. He was a member of the 

 Conchological Society of Great Britain and Ireland, and for a 

 number of years held office on the council of that institution, and 

 was for a period of three years its president. He was also a 

 member of the Philosophical Society of Glasgow, and a member 

 of the West of Scotland Marine Biological Association. He was 

 deeply interested in the movement which resulted in tlie 

 establishment of the Marine Biological Station at Millport, and 

 took an active part in obtaining the funds necessary for its 

 equipment and maintenance. His personal efforts were instru- 

 mental in obtaining many valuable gifts, alike from private
