Miscellaneotts. 463 



Lake Superior, distinguished by the same prominent assemblage of 

 characters. It ranges, in this country, with L. auricularia, not 

 being found in Scotland, and appearing extremely rare and local in 

 England, north of the midland counties." 



In the summer of 1857, whUe engaged in looking over the collec- 

 tion of Moflusca of the late Prof. Fleming, of Edinburgh, he men- 

 tioned in the course of conversation that the LymncBa stagnalis was 

 reported to have been obtained by the late David Don, the botanist, 

 in Gulane Loch, between seventeen and eighteen miles to the east of 

 Edinburgh ; but that, so far as he was aware, its occurrence in the 

 aforesaid locality had not been confirmed by any subsequent ob- 

 server. At the same time, he strongly recommended me to attempt, 

 if possible, to ascertain the truth of the report. Accordingly, since 

 that time I kept a sharp look-out for this interesting species in the 

 habitat specified. It was not, however, until the 30th of April of 

 the present year that my eiforts were crowned with success, when I 

 succeeded in procuring abundance of excellent specimens. 



Gulane Loch is a sheet of water of inconsiderable depth, but of 

 some extent, in the sandy common of the same name, which slopes 

 gently downwards to the seashore in the neighbourhood of the small 

 village of Aberlady. Owing to the extent and variety of its surface, 

 this common has for a long time been known to the botanist as a 

 locahty for rare plants, several of which occur in the loch itself,— 

 e. g. Utricularia rmlgaris, Menyanthes trifoliata. Slum repens, and 

 other plants which are not commonly met with in the adjoining 

 district. Owing to the water being very much choked up with 

 aquatic plants, it becomes a matter of very considerable difficulty to 

 drag it with a net, more especially in the middle of summer, when 

 the plants have grown up ; and to this I attribute my want of success 

 hitherto ; for, on visiting the locaUty last month, which was much 

 earher than my wont, and when most of the plants were yet beneath 

 the surface of the water, I easily procured the specimens already 

 mentioned. The animals were generally clinging to plants of the 

 genus Char a, near the surface of the water, and were associated with 

 individuals of Lymncea peregra, L. palustris, Physa fontinalis, 

 Cyclas cornea, and various small species of Planorbis. I brought 

 home about two dozen specimens, the greater number of which are 

 at present in a state of captivity, and appear to be, on the whole, 

 very active. I think it of some importance to record this fact, be- 

 cause of its interesting relation to the geographical distribution of 

 this so much the finest species of our British Lymnaeae. Should 

 Mr. Reeve desire to possess Scotch specimens of it, I shall be only 

 too happy to furnish him with them.
