NATURAL HISTORY SOCIETY OF GLASGOW. 187 



Mr James Lumsden exhibited a monstrosity of the domestic 

 Duck, with three legs. It had lived upwards of a week. A similar 

 specimen of the common Dorking Fowl was exhibited by Mr John 

 Gilmour, the chairman remarking that in both cases the extra 

 limb looked like a union of two of imperfect development. 



Dr Stirton exhibited a series of mosses from New Zealand, 

 collected by Mr John Buchanan of the Government Geological 

 Survey, Wellington, N.Z., a corresponding member of the Society. 

 Dr Stirton stated that the natural history of New Zealand had 

 been very thoroughly investigated, but although many of the 

 species now exhibited were well known, many of them were rare, 

 and three if not four of them were not included in any Antartic 

 flora, and were still undescribed. The most interesting one of 

 these, which he proposed to name after his correspondent, was 

 thus described: — 



I. Qrimmia huchanani (Stirton, M.S.). Stems loosely tufted, 

 leaves oblong amplexicaule, plane margined, laxly areolated, ter- 

 minating abruptly in very long green nearly entire subulae, which 

 are composed almost entirely of the prolonged nerves, perichaetial 

 leaves longer and narrower at the sheathing bases, otherwise 

 identical, fruit stalk curved, capsule ovate, regular, furrowed when 

 dry, pale, lid conico-rostrate, oblique, more than half the length 



"of the capsule, calyptra dimidiate covering half the capsule, teeth 

 deep-red at base, curved, bifid into long pale subulate points, 

 inflorescence in all likelihood dioicous, antheridia not detected. 



II. Tortula incurvidens (Stirton, M.S.). Stems gregarious, short, 

 leaves lanceolate with plane entire margins, crisped when dry, 

 texture dense, opaque above, pellucid and quadrangular at base, 

 nerve strong, indistinct near apex, which is somewhat cucullate, 

 capsule red, erect on a thick red seta arising from a basilar mem- 

 brane, broad and prominent above the mouth of the capsule, 

 irregular, rough with minute papillae, and crossed by two or 

 three septa, incurved when dry, converging into a cone when 

 moistened, lid obliquely rostrate, subulate, nearly as long as the 

 capsule, calyptra dimidiate, extending more than half way down. 

 Approaches in several of its characters to Tortula ambigiia, but 

 diverges widely in others. 



III. Bryum contoiium (Stirton, M.S.). Dioicous, densely caes- 

 pitose, stems radiculose, lower leaves small, scattered, upper 

 suddenly enlarged, closely imbricated in a moist state, contorted
