in three or four places in England; the present is the only 

 other known station. Also Zygodon Mo^igeotii, the only speci- 

 men, in a fertile state, detected in Great Britain, with the 

 exception of Professor Walker Arnott's solitary capsule secured 

 on the Glova Mountains; Hijimum rugosum, barren, which occurs 

 very sparingly, and is a]3pareutly confined to one spot; Bartramia 

 cakarea, fruiting freely, with abundance of male plants showing 

 the distinguisliing characteristics in the perigonial leaves; Bar- 

 tramia arcuata, a fertile specimen ; and several others of secondary 

 importance, which, although deserving of notice, are yet to be 

 met with sparingly throughout the country. Dr Stirton also 

 exhibited, from the Trossachs, specimens of a rare and beautiful 

 moss, Dicranum spurium.

SPECIMENS EXHIBITED, 



Mr David Eobertson exhibited specimens of Amj)hiura Chiajii 

 (Forbes) from Cumbrae, and remarked that, during his dredging 

 expeditions, he had found the species off Largs, and at Wemyss 

 Bay, Oban, Inveraray, Gairloch, Loch Long, Loch Goil, Holy 

 Loch, Rothesay Bay, and west of Bute. He characterised it as 

 the most common star-fish on all the mud banks, ranguig from a 

 depth of 20 to 40 fathoms, round the shores of the West of Scot- 

 land, and commented on the extraordinary fact of its being 

 entirely overlooked by one of the keenest observers — the late 

 Professor Forbes — in his numerous dredgings in the Firth of 

 Clyde. This distinguished naturalist had, in all likelihood, passed 

 it over as Ophiocoma fiUformis, with which it is invariably found 

 associated in the same habitat. Mr Robertson also exhibited 

 specimens of Tanais hirticaiidata (S. Bate) and Priniza ohesa, both 

 from Douglas Bay, Isle of Man, where they had been discovered 

 by Mrs Robertson. He stated that this Tanais had long been 

 familiar to him at Cumbrae, but he was unable to distinguish the 

 species. He had, however, submitted his specimens to Mr Spence 

 Bate for determination, and had now to record both these animals
