Of the foregoing species (about 125) 58 inhabit Britain, 98 to 

 100 the Mediterranean or coasts of Portugal (including all the 

 British species) ; of those remaining, 16 are common to the Ca- 

 naries, 1 (a Tellind) to Mogador, leaving 3 species of Rissoa, 2 of 

 Emarff inula, 1 of Scalaria, 2 of Argiope, and 1 of Turrit ella, sup- 

 posed to be new. ii o>^ jum

In- commenting upon the genera of the Icacinacea, I "kmk fre- 

 quently spoken of Phlebocalymna, a manuscript name proposed 

 by Mr. Griffiths for a plant collected by him in the Malacca 

 Peninsula, but as I am unable to discover that any of its cha- 

 racters are appreciably distinct from the Platea of Blume, the 

 former must necessarily merge into the latter genus, which was 

 first established by that distinguished botanist in his ' Bijdra- 

 gen,' and more lately recorded in his ^Mus. Bot. Lugd.,' 

 where he enumerates another new species. In describing the 

 characters of Stemonurus, I have stated {ante, p. 32), that the 

 chief or perhaps only feature that can distinguish Platea, is the 

 absence of the glandular hairs, that form a beautifully fringed 

 crest over the anthers in the former genus, and as this was 

 believed only to be a sexual difference, I had considered Platea 

 as identical with Stemonurus. In the former, as also occurs in 

 many species of the latter genus, the filaments are said by Blume 

 to be short and broad (whence probably the generic name from 

 irXareia, amplus), while in Phlebocalymna, although when in bud 

 they are short and broad at base, they become afterwards long and
