314 PROCEEOINGS OF SOCIETIES. 



Eev. E. O'Meara exhibited some specimens o^ Melosira varians 

 in which the endochrome-plates were very obvious even when the 

 frustules were fresh ; in the case of others, treated with dilute 

 hydrochloric acid, the " plasm-sac " surrounding the sunk-in cell 

 contents were composed of large somewhat oval granules, and in no 

 case did they exhibit the stellate appearance described by Pfitzer 

 in his paper in ' Ueber Bau und Entwickelung der Bacillariaceen,' 

 t. vi, f. 5, 6, 7. 



Mr. Crowe showed Staurastrum sexcosfatum from the little 

 Stephanosphaera-pool on Bray-Head, this desmid being for the 

 first time noticed in that very restricted station. 



Mr. Archer was at last fortunate enough to be able to present 

 fine active living examples of the singular little animalcule recorded 

 already by him, but not before able to be exhibited, Drepanomonas 

 dentata (Fresenius). He was also able to show Cosnomorpha 

 medusula concurrently, once before exhibited to the Club. 

 Both are sufficiently interesting on account of their singularity 

 of form, and may, he thought, be regarded as decidedly rare. 

 Mr. Archer likewise showed a pretty copious gathering of the 

 apparently rare little alga Sciadium arhuscula (A. Braun). Its 

 (no doubt) "relative," Oplnocytium Agardhianuvi minus (Nag.), 

 is on the other hand common, but the form majus is seemingly 

 rare. 



Dr. Macalister showed preparations of the mucous membrane 

 of the tongue of Glilamydophorus truncafus, showing the long 

 recurved filiform papillae and the rounded smooth fungiform 

 eminences, covered with squamose epithelium ; some of the 

 former were divided at the summits, and were longer around the 

 edges of the tongue. 



Hev. E. O'Meara read a translation by him of a communication 

 from Judge Mouchet, Rochfort-sur-mer, France, on Illumination, 

 and gave notice that he would propose that gentleman (who was 

 seconded by Dr. Barker) as a Corresponding Member of the Club 

 on the next night of meeting.
