Mr. F. W. Moore exhibited Verlid/Iivm latertiiim,'Etrt. It was found 

 growing on a piece of decaying stem of Cattlcya Doiviana, which had been 

 imported recently from Costa Rica, on which it formed bright red 

 patches. Under the microscope the colour did not appear nearly so 

 brilliant as in the growing condition. 



Mr. G. H. Carpenter showed preparation of the head of the sea-midge, 

 Cliinio marimis, Halid., drawing special attention to the large size and 

 circular shape of the eye-facets, and to the vestigial condition of the 

 jaws. 



Dr. Scott showed sections of caries of teeth prepared by Dr. Baker, 

 showing the micro-organisms filling the dentinal tubules— also photo- 

 graphs of the sections coloured to represent the original sections. 



Proe. G. CoIvE showed a section of banded Gneiss from Cushendun 

 Co. Antrim. It has been recognised that some gneisses result from 

 parallel igneous intrusions. In this case a eurite has formed parallel 

 veins in what appears to be an altered basalt, and granular crystals of 

 quartz and felspar from the eurite appear scattered in the latter rock. 

 Deformation of the mingled rocks, accompanied by re-arrangement and 

 re-crystallisation of quartz and felspar, has gone on subsequently to 

 the intrvision. 



Mr. M'Ardi^E exhibited specimens of Lejeunca calyptrifolia. Hook., in. 

 fruit, which he collected last year at Auniscaul, Co. Kerry. On account 

 of the small size and scarcity of the plant it is rarely met with in this 

 condition. The perianth is large for the size of the plant, somewhat 

 campanulate in ovitline, with five projecting angles or teeth at the apex, 

 which are decurrent to the base. Cal3^ptra spherical, strongly reticulated, 

 with a stalk or peduncle about twice its length, divided by transverse 

 septa into a number of tubular-like cells. 



Mr. W. N. AivTvEN exhibited a drawing of Scapania aspera, Mull. ,. which 

 he made from plants collected by Mr. M'Ardleinthe Co. Cavan. The 

 plate shows a plant the natural size, portion of a branch, magnified 

 leaves and leaf cells, bracts, perianth with spinose ciliated mouth highly 

 magnified, a shoot wdtli gemmae at apex of leaves. Mr. Allen also 

 exhibited a good figure of Metzgeria conjugata (Dill) Lindb., clearly showing 

 the moncecious character of the plant. These excellent delineations 

 with others are for Mr. M'Ardle's coming paper on plants collected by 

 him in the Co. Cavan for the Flora and Fauna Committee of the Royal 

 Irish Academy. 



Professor A. C. Haddon exhibited sections of a small sea-anemone 

 commensal with a calcareous polyzoon which he had collected in Torres 

 Straits. The actinian has not yet been determined, but it is probably the 

 same as that recorded by Prof, W- A, Haswell, in the Proc. L. S., N. S. 

 Wales, vol. vii., p. 608. 



January 17th.— The Club met at Dr. Frazer'S. 



Prof. G. C01.E showed the glassy edge of an oliviue-basalt dyke, S. of 

 Annalong Port, Co. Down. This is a pleasing and transparent example 

 of basalt passing into brown tachylyte, with very trifling development 

 of magnetite, so that the glass resembles the modern examples from the 

 Pacific islands far more than the well-known and darker types from the 

 western isles of Scotland. 



Mr. F". W. Moore showed Ncdria sangtiinea, Fr. This pretty and 

 interesting species was found growing on a decaying pseudo-bulb of an 

 unnamed Eriopsis imported fiom Brazil. As seen growing, the colour was 

 extremely bright, but under the microscope it was much duller. It 

 belongs to Cook's fourth section '« Denudatse," and is characterised by 

 having the perithecia ovate in shape, and blood red in colour, the 

 sporidia being elliptical and colourless.
