The Natuealist. 



ensuing year, a British Botanical Bibliography, to include a reference to 

 all that has been published during 1880 upon British plants. He would 

 be grateful to any private individuals or local societies for any publica- 

 tions they may have or publish, giving a record of what is being done in 

 local botany by them. Communications should be addressed to Mr. 

 James Britten, F.L.S., Editor of Journal of Botany, Natural History

Additions to the West Riding Flora. — Dicvanella heteromallaj 

 var. elata, Ferg., a very tall form, Marsden Moor. Limnobium ochra- 

 ceum, var. flaccidum, Milde, a long distinct form in a rill near 

 Marsden. Hypnum cupressiforme, var. lacunosum, a fine robust 

 form occurring on limestone walls in sub-alpine districts. Tricho- 

 stomum crispuhim, var. elatum, Gordale. Madotheca porella, gathered 

 from a rock in CoUingham Bank Wood. Chantransia violacea, 

 Ktg., growing on Lemanea fucina, Borg., on rocks in the stream 

 which pours down Gaping Ghyll, Inglebro', both species being new. 

 Gloeotila mucosa, Ktg., in a pool on Malzeard Moor. Conferva Funkii, 

 Ktg. , and Ulothrix tenuis, Ktg. , at Frizinghall Dam. Fragilaria muta- 

 bilis, Sm., very abundant in a well at Marsden. Gomphonerna constrictum, 

 Ehrh., near Wooley. Gloeocijstis vesiculosa, Naeg., Rawcliffe Common, 

 Asterionella formosa, Hass., near Wetherby (or Bradford). There is an 

 uncertainty as to the exact habitat of the last-mentioned plant. About two 

 months ago I gathered some very fine fruit of Campylopus turfaceus, near 

 Wetherby ; the ripe spores were shed in such abundance in drying, that 

 I placed some on slides, and carefully laid covers on them, placing them 

 in a large evaporating dish with Bradford tap-water, covering the dish ' 

 with sheet glass. This was done to grow the protonema of the moss. • 

 When I looked for protonema I found an abundant crop of fine examples 

 of Asterionella formosa on the slips and covers, and I am unable to 

 pronounce whether it originated from the Bradford tap-water or the 

 Wetherby spores and dust, though 1 lean to the latter, because thej 

 Asterionella grew all over the bottom of the dish, the slips, and covers ( 

 quite away from the sown spores as well as near them. I have now sown 

 the bottom of the evaporating dish with small glass circles, in anticipation 

 of a fine harvest. — Wm. West, Bradford. 



Coremia munitata. — Correction. — The insect which I took at Wharn- 



cliflfe was, as Mr Harrison suggests ( Naturalist vi., p. 4:2.), C. propugnata, 



and it was under that name that I exhibited it to the Leeds Naturalists' 



Club. The mistake was made by the member who wrote down the name 



of my insect from my dictation for the secretary's use, and he either 



misunderstood me, or else wrote munitata for propugnata inadvertently. 



At all events, I showed the insect under its right name. Our secretary is 



not to blame either, for he copied the list as supplied to him. — Charles
