Class DIATOMACEiE = BACILLARIEiE 



Achnanthes minutissima, Ktitz. (59.) Pond in Bot.

 Meridion circulare, Ag. 

 Diatoma elongatum, Ag. 



— vulgare, Bory. 



Surirella biseriata, Brib. Chorlton Fields 



Meloseira varians, Ag. 



All the above diatoms are recorded in Buxton's 

 Guide App., and are said to be more or less com- 

 mon, but no locality is given excepting as quoted 

 above. Presumably they were found in the 

 Lancashire area, otherwise they would not be 

 considered common about Manchester. 



The following from Buxton's G. App. must be 

 considered ambiguities if not errors : — 



Gyrosigma hippocampus, Hass. 

 Shinctocystis librilis, Hass. 

 Fragilaria pectinalis, Lyngb. 



— hyemalis, Lyngb. 



— rhabdosoma, Br6b. 

 Navicula platystoma, Ehr. 



There is also Mr. Comber's list of Diatomaceas 

 found in the neighbourhood of Liverpool, publ. 

 in Trans, of Historic Soc. of Lane, and Chesh., 

 vol. xi. 1859. 



Mr. J. A. Martindale very kindly furnished a summary of Fresh Water Algas, and one of 

 Desmids only, for Westmorland and Lake Lancashire, V.C. 69. Diatoms are not included, there 

 being no reliable information in reference to them. The lists were very carefully drawn up bjr 

 Mr. Martindale, from the Journal of the Roy. Microsc, Soc. 1884, 1 886, and 1 892, and the plants 

 were collected and vouched for by Mr. J. P. Bisset, Alf. W. Bennett, and Wm. West. The total 

 number of species recorded, 35 Fr. Water Alga (excl. Diatoms) ; 167 Desmids, for V.C. 69. Lake 

 Lancashire. The district is the Lancashire Leven, that is, the lower portion. Less time was spent 

 here than in the upper (Westmorland) portion ; the number of species is therefore greater for the 

 latter. Mr. Martindale, however, thinks the lower Leven basin will be found quite as rich in forms 

 as the upper.
