distance as Wicklow and Kerry), he bad almost begun to think 

 it lost to ken, and, indeed, it had only on the present occasion 

 presented itself in a single gathering out of two or three dozen 

 which had been taken at Grlencar. — The examples of Amphizonella 

 vestita observed were without chlorophyll-granules, but covered 

 by more or less well-developed external hair-like processes ; were 

 pretty active, and possibly very slightly smaller in dimensions 

 than those originally met with. 



Amongst other rare Rhizopoda taken on same occasion there 

 occurred examples o^ Euglypha spinosa, Carter (' Ann. Nat. Hist.,' 

 3rd ser., vol. xv, p. 290). This was the first time found in Ireland, 

 and Mr. Archer was not aware of its having been met with by 

 other than its original discoverer, Mr. Carter, nor by him in any 

 new site. It is quite a striking form from its comparatively large 

 size. A good opportunity presented itself to obtain a transverse 

 view, as one specimen obligingly became tilted up " on edge," 

 frontal opening downwards, and retained that position for a length 

 of time. Its striking size, lenticular shape of the test, and long 

 very bold spines fringing its extreme edge, its nearly elliptic out- 

 line in the broad view, and its wide, arched anterior opening, 

 would seem to forbid this form being mistaken for any other 

 Euglypha. So far as Mr. Archer knew, this was the second 

 instance of its occurrence, and here it was very scanty.

Hev. B. O'Meara showed some preparations from Diatomaceous 

 material from Sulu Archipelago (north of Borneo), forwarded by 

 Captain Chimmo, R.N., containing many rare forms of interest ; 

 one of these, new, Mr. O'Meara named Navicida Ghimmoana ; the 

 material required working up, and he would revert to it on an 

 early occasion. 



Dr. E. Perceval Wright exhibited some mounted specimens of 

 the calcareous bodies from the integument of Cucumaria modesta, 

 Selenka. He had forwarded a collection of Holothuroids made 

 at the Seychelles to Professor Selenka, and lately he had had a 

 list of the species returned to him ; among these were two new 

 species, Phyllopliorus rapModerma, and the species of which some 

 of the calcareous plates were now exhibited. A full list of the 

 species, with descriptions of the new ones, will, it is expected, be 

 published in a short time. 



Mr. Thiselton Dyer exhibited longitudinal sections from the 

 stem of the plant of Pandmius utilis, which had recently been 

 destroyed by a fungoid disease at Grlasnevin. He was anxious to 

 call attention to a point in the structure of the fibro-vascular 

 bundles which, as far as he knew at present, was altogether novel, 

 at least it was not noticed in any of the more common authorities, 

 though it could not have been completely overlooked. Round 

 the periphery of the proseichj^ma of the bundles, and arranged 

 parallel to them, were striuj^^ or wingio rows of parenchymatous
