This, according to Mr. Couch, is distinguished from the 
preceding by having the bent necks of the cells turned in 
opposite directions, and the bristle below, instead of above, 
the orifice. We had never seen this till it was kindly sent 
to us from Hxeter by the Rev. T. Hincks.

** Under the bowers 
Where the ocean Powers 
Sit on their pearled thrones ; 
Through the coral woods 
Of the weltering floods, 
Over heaps of unvalued stones ; 
Through the dim beams 
Which amid the streams 
Weave a net-work of coloured light ; 
And under the caves, 
Where the shadowy waves 
Are as green as the forest’s night.”—Shelley. 
* Mrs, Gatty, of Ecclesfield, has discovered capsules on Hippothoa diva- 
ricata ; Mr. Peach thinks he has discovered them on H. catenularia.
