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. Summary of Fr. Wtr. Klgm (exclg. Diatoms). V.C. 69 Palmellaceae .
