Forskal, in liis description of Animals of the East, published in 1775, 

 in describing Helix lanthina, p. 127, observes : — "lanthina in vas- 

 culo aqua marina pleno, viva servata ; altero mane mortua, e labiis 

 proboscidis extrusit menibrum globosum apice umbilicatum, hyali- 

 num, venis longitudinalibus, violaceis. In fundo vitri parvse arenulse 

 videbantur punicese ; quae microscopio inspectse, cochleae erant, matrem 

 testa simulantes, non colore ; corpore quoque dispari ; nam ad ai^ev' 

 turam duo vela transversa, subrotunda, pilis tremulis ciliata ; qui- 

 bus pulU hi remigabant : quique sine dubio soboles erant majoris 

 conchae ; quum aqua aliis hospitibus non mixta fuerat. Quid ? quod, in 

 multis aliis vitris postea viderim lanthinas demittere tales conchulas, 

 matrem circumnatantes. Matricem in proboscide esse putaverim, 

 quum alia non apparuerunt ejus vestigia." In tab. 40. f. c 6, these 

 young lanthince with the two fins are well figured. His editor gives 

 no explanation of the figure, 5^piip^^,|^^^%,i^J^be)^^)r^409.^^^

Nptiaeiii^jthpjfficur^ence o/' Eleocharis uniglumis, LinkynearJBf^^^ 

 ,,, f ness Castle, Linlithgowshire. By John T. Syme, Esq.j*' ^jfpj 



Among the plants recorded as British since the publication of tjsi 

 Society's Catalogue in 1841, the Eleocharis uniglumis, Link, \% 

 mentioned in the second edition of the * Manual of British Botany' ai 

 having been found at *' Aberdeen, Dr. Dickie, and Barvas, Isle of 

 Lewis." I have found it also in Mull and near Swanbister, Orkney, 

 but I am not aware that it has been noticed in this neighbourhood 

 until it was found in the botanical excursion made by Prof. Balfour 

 and his class on Saturday June 1st, 1850, when it was discovered 

 grovring in a marsh to the east of Blackness Castle, Linlithgowshire. 



It is very probable that it is by no means a rare plant ; but as it is 

 similar in habit to E. multicaulis, I subjoin the characters by which 

 it may be distinguished both from that and from E. palusttris, to 

 which it is in reality much more closely allied. .boo/jb*37 gmyd ?!loq8 



In E. uniglumis the root is creeping quite as nAich'»9;iiy'jy. jprtl 

 lustris, while it is very slightly so in E. multicaulis, which may be 

 easily pulled up by the hand. The glumes are acute with a very 

 narrow membranaceous margin. Stigmas 2 ; *' nut obovate obtuse, 

 rather compressed, shorter than the/bwr bristles." [I have never seen 

 the perfect fruit myself, but give the characters from the Manual of 

 Brit. Bot. ed. 2. p.* 349, and Koch, Syn. Flor. Germ. ed. 2. p. 852.] 



In E. multicauli.s the glumes are obtuse with a broad membrana- 

 ceous margin. Stigmas 3 ; nut oblong ovate, acutely triquetrous, as 

 long as the G bristles. The sheaths of the stem are also much more 

 obliquely truncate than in E. uniglumis, in which they are nearly 

 transverse at the upper extremity. The nuts are of a darker colour 

 according to Koch. 



It must be confessed that E. uniglmnis comes very near to E, pa- 

 lustris, which is ho\vever usually much larger and stouter ; but the
