NOTE UrON THE RIMDLARIA LIMBORINA. 129 



cloven in an irregular manner, in place of opening by a rounded 

 pore as in the Verruccmd^ or by a radiated star, as in the genus 

 Limhoraria. But after the rimular dehiscence, the superior parts 

 of the conceptaclc, although divided into angles sometimes slightly 

 regular, are none tbe less continued in a very evident manner, and 

 without any line of demarcation with the inferior part of the same 

 conceptacle. It is not, therefore, necessary, in order to explain the 

 origin, to have recourse to a pretended epithecium which may be 

 formed by the summits of the thecae and of the paraphyses swell- 

 ing, altering, and bleaching. A similar epithecium exists at times 

 upon the disc of the apothecia of the Lecidea inconcinna, as M. 

 Nylander has reniarked, but not in the Rimularia limborina.

FOEM OF RHYNCOSTEGIUM. 



A very beautiful form, not, I think, recorded as British, occurred 

 in Derbyshire. Ehijncostegium rusciforme, var. inundatum, Bry.

STENOGEAMME INTEEEUPTA, Ag. 



A note has been published by Dr. Perceval Wright, in cor- 

 rection of the notice of this species by E. M. Holmes, in 

 "Grevillea" for December, 1874, on four points, (1) that the 

 tetrasporic fruit had not been recorded as occurring in Britain ; 

 whereas in Harvey's " Nereis Bor. Amer." (part ii.. Mar., 

 1853) it is described from specimens (a) from Somersetshire, 

 {b) from Cork Harbour. (2) That it is not described in any 

 recent works on Alg« in Britain ; whereas a description will be 

 found in Harvey's " Phycologia Australica," as well as the work 

 above alluded to. (3) That no figure of the tetraspores had been 

 published ; whereas, in pi. ccxx., figs. 2, 3, 4, 5 of Vol. iv. of 

 Harvey's " Australian Algae," they will be found. (4) That no 

 notice was taken by Dr. Harvey of specimens sent to him by Miss 

 Gifford, in 1848; whereas the letter and specimens are in the 

 Herbarium of Trinity College, Dublin, and the priority of Miss 

 Gilford's discovery of the tetraspores is fully acknowledged at p. 

 169 of Part II. of the " Nereis Boreali- Americana." Finally, as 

 the specimens figured in " Grevillea," pi. xxxvii. are stated to 

 have been gathered in Scotland, it would be interesting to know 

 from what part, as this would be the most northern habitat as yet 

 known.
