124 PROCEEDINGS OF THE 



moss on Kinnoul Hill and Balthayock. Although this is the first 

 notice of the moss occurring in Great Britain, it is not unlikely to 

 be found in other localities, as from its general resemblance to a 

 form of Giimmia pulvinata, it is apt to be overlooked. Dr Stirton 

 exhibited specimens of Camfijlopus compadus and Bryum gracile. 

 In addition to these, Dr Stirton laid on the table specimens of 

 Stylostegmm ccespiticmm, from Ben Lomond, the second locality in 

 Great Britain, where it is found in great abundance, and Tricho- 

 stomum crispulum, from near Cardross, Bowling, etc. — a very 

 characteristic moss, apparently common on our seaboards, but 

 strangely overlooked in Scotland. 



Mr David Robertson exhibited specimens of Cypridina marice 

 and Philomedes longicornis, both from the Firth of Clyde. Mr 

 Robertson stated that he had procured the latter in great abund- 

 ance in the surface net; and with regard to the former, although 

 previously recorded as rare in the three localities where it had 

 occurred, he noticed the fact of its being very common at Cum- 

 brae. He likewise mentioned a curious diversity in the habitat 

 of these animals, namely — deep water at Plymouth, in tide pools 

 at Herm, and on the surface in the Firth of Clyde. 



Mr Alexander M'Kinlay exhibited the following mosses new to 

 Britain: — Didymodon daldinianus (De Notaris), in fruit, from Ben 

 Voirlich — a species closely allied to D. cylindricus; Barhula fragilis 

 (Wils.), from near the summit of Ben Lawers — a very distinct 

 species, first discovered by Drummond in the Rocky Mountains, 

 and found in various localities on the Alps of Europe, from 

 Switzerland to Scandinavia; and Myurella apictdata (Sch. Syn.) 

 from Craig Challeach, growing sparingly, interwoven with Enca- 

 lypta commufata. The latter has been overlooked as a form of its 

 congener, M. julacea (Leskea Tnoniliformis), but is distinct in its 

 spreading, concave, papillose leaves, with long apiculus. It also 

 is a Scandinavian species. 



The Secretary exhibited a series of Silurian Brachipoda from 

 the neighbourhood of Girvan, embracing about twenty-five species, 

 one of which was undescribed. Among these were Lingula 

 Ramsayi, and L. attenuata, Discina perrugata, and several others of 

 equal interest.
