Riding-, on 19th December 1902. I believe it is an addition to 

 Yorkshire hepatics. It was associated with the rare Fossomhronia 

 cristata, and both hepatics were abundant. It is noteworthy 

 that in the same month Riccia glaiica occurred in a similar field 

 on Strensall Common, but unaccompanied by a Fosso7nbronia. — • 

 Wm. Ingham, 15th October 1904. 



Jungermania minuta Crantz. — This very minute and rare 

 hepatic I found in a wood on Strensall Common on i6lh August 

 1904. It was growing on dead sticks and bits of heather, and 

 associated with Lepidozia trichoclados C. Mull. This latter was 

 first described as a British hepatic in 1902 by Mr. Macvicar. 

 I believe Mr. Slater has this Lepidozia from Wheeldale, Goath- 

 land, in one of his old gatherings. Mr. Macvicar approves 

 of my naming of the above hepatics. — Wm. Ingham, 15th 

 October 1904. 



Scapania aspera in West Yorkshire. — Mr. Ingham states 

 on p. 309 of 'The Naturalist' for last month that this species 

 has 'not hitherto, I believe, been recorded for the West Riding.' 

 It was recorded by me on p. 12 of this periodical for January 

 last as being frequent in every limestone district of West York- 

 shire. I distributed numerous specimens over twenty years ago 

 under the name then given to it by my constant correspondent, 

 the late H. Boswell, of Oxford. I always thought that it might 

 be another species, so when sending my friend Mr. Macvicar 

 a large number of Scottish species for his forthcoming ' Census 

 of Scottish Hepaticas,' I took the opportunity of sending him 

 specimens from between Buckden and Grassington, etc., and he 

 pronounced them to be true S. aspera. — W. West, Bradford. 







ALG/E. 



Diatoms at Spurn. — Some rather interesting gatherings 

 were made from algae growing in tidal pools on the Humber 

 side of the peninsula on the occasion of the recent visit of the 

 Yorkshire Naturalists' Union to Spurn. The most noteworthy 

 were an abundance of Actinocycliis Roperii, a species which 

 Norman records (under the old name of ' Coscinodisciis ovalis'), 

 as rare in Ascidian gatherings. The fact that it is now found 

 plentifully at Spurn goes to confirm my previously expressed 

 opinion^ that all the species found by Norman in the stomachs 

 of Ascidian Molluscs may eventually be discovered on our coast.
