and aquatic species.! In these two papers Mr. West gives 
the vegetation of these lakes (including in many instances 
mosses, lichens, and algz) in their submerged, littoral, 
and surrounding conditions. 
He discusses many subjects, and these papers, it is to be 
hoped, will be followed up by others, after the manner of 
Dr. Magnin with the French and Swiss lakes of the Jura,” 
and the United States in Bull. Michigan Fish Commission, 
No. 2, “ The Plants’of Lake St. Clair,” A.) J) Fite 
1. Ranunculus Flammula, L., var. natans (Pers.).—This is 
a remarkable form of Flammula found by Mr. West in two 
places, a floating form at the margin of peaty pools about 
Morton Lochs, Tents Muir. “A strong plant 2 to 3 feet 
long,” and a submerged form in the margins of lochs and 
slow streams in water 6 to 24 inches deep. Abundant in 
Lochs Recar, Ballochling, etc. (Kirkcudbright). Persoon 
describes this as “y zazans, fol. inferiorib. ovatis integris, 
superioribus linearibus,” “Syn.,” pl. v., ii. (1807), p. 102. Re- 
corded from the same place by Lamarck in “ Ency. Meth.,” 
v., vi. (1804), p. 98, but given no name.? 
2. Ranunculus lingua, L.—The early submerged leaves of 
this species, first called attention to by the late Mr. Roper,* 
are so unlike the flowering stage leaves that unless one had 
watched the plants it could hardly be believed ; they are 
8 to g inches long by 3 inches wide, and in those I watched 
were quite decayed when the plant flowered. 
3. Peplis Portula, L.—Mr. West found an entirely sub- 
merged form in Loch Doon (50 to 100 feet deep), Fife, 
“srowing to a length of 3 feet with larger, thinner, semi- 
pellucid leaves, stems weak.” This is quite beyond anything 
I have seen; I have gathered it in Surrey (submerged) 
13 inches long only. 
4. Hydrocotyle vulgaris, L.—Usually a creeping species
