I. Note on Chlamydomyxa labyriuthnloides. Archer. By Mr 

 Patrick Geddes, F.Pt.S.E. 



This remarkable organism was discovered by Archer in the ceUs 

 of Sphagnum, and described by him in the "Quarterly Journal of 

 Microscopical Science " for 1875. The lamination of the cell coat- 

 ings, and the formation of j)eculiar wart-like thickenings inclosing 

 red pigment, were considered as tending to support the old view 

 of growth by accretion of successive laminae. The occasional col- 

 lection of the chlorophyll into definite patches — incipient chloro- 

 phyll grains — was also described. A distinct resting protococcus 

 stage occurs early in development. 



On these grounds it was pointed out that this organism could 

 not be satisfactorily referred to any existing animal or vegetable 

 group, since it presented close affinities with the Ehizopods on the 

 one hand, and with the Palmellaceous Algaj on the other. A more 

 perfectly intermediate type, indeed, cannot be imagined. 



An interesting and animated discussion followed, in which the 

 President, and Professors Dickson and Ramsay Maci!^ab of Dublin, 

 took part.
