The Naturalist. 



which is a good addition to the lepidopterous fauna of Upper Wharfedale, 

 and happily confirms Mr. Porritt's surmise (see Nat. N.S. . viii., p. 27) 

 that he had seen it at the Union's excursion to Grassington in 1882. 

 Another species amongst others taken there by my brother may be 

 worth recording, viz., D. lievhosana. — E. P. P. Butterfield, Wilsden, 

 Bingley, Sept., 1883. 



[The interest of the capture of *S. conspicualis at Grassington is further 

 enhanced by the fact that the specimen was taken in June, as it points 

 strongly to there being two broods during the year of this comparatively 

 recent addition to the British list. Previously the species had only been 

 recorded as occurring in August. — G. T. P.] 



Nephrodium cristatwn. — A Correction. — Dr. F. Arnold Lees has 

 kindly called my attention to an erroneous statement in my List of York 

 Ferns {Naturalist, July, 1883, pp. 178 and 181), with regard to the first 

 finding of this fern at Askham Bog. Mr. West and I certainly discovered 

 it in September, 1875, without having the least idea that it had been 

 previously found there : but as Dr. Lees has referred me to more than 

 one previous record of it, I hasten to correct the error. He says : "In 

 Watson's ' Topographical Botany ' (1873-4) it stands recorded for the 

 south-west division of Yorkshire, with a query for the mid-west division 

 also. Askham Bog comes within the latter area. Mr. John Hardy, now 

 of Manchester (formerly of Sheffield), first added it to the Yorkshire 

 flora, having got it on the border of Thorne Waste. In 1872 I confirmed 

 that "find " by gathering it there myself in small quantity in a boggy, 

 bushy place. In 1873 I gave the S. W. division of Yorks. to Mr. Watson 

 for it. A year, or perhaps two, later (certainly before 1875), when I 

 lived at Leeds, Mr. Henry Ibbotson told me it grew on the bog at 

 Askham. He had, I understood, found it himself. It occurs in a MS 

 list of his which I hold, furnished to me when I was preparing my work 

 on ' West Yorkshire ' (including the Ainsty). I went to the bog and 

 gathered a frond or two myself ; as you say, it is very scarce, and 

 peculiar in habit of pinna-insertion, &c. To Mr. Ibbotson, who is a good 

 botanist, and discovered it independently of you, belongs the credit of 

 leading me to gather it and publish it in 1875 for Askham Bog, in ' West 

 Yorkshire ' (p. 324-5)." Of course I have no further wish to claim to 

 have first discovered this fern in Yorkshire, and would have corrected 

 the error earlier had not temporary absence from England prevented me. 

 Probably I should not have overlooked these previous records had I not 

 been for some years separated from Yorkshire and its botanists. — Robt.
