Various Short Notes. 



does not specially emphasise the valuable work done by the 

 East Riding- members. To Mr. J. W. Stather, F.G.S., and to 

 Mr. Sheppard himself, acknowledgments are specially due for 

 researches carried on (for some nine years now) in a thoroughly 

 systematic manner, with unceasing- care and unflag'ging energy, 

 and great assistance has also been rendered by Mr. F. F. Walton, 

 F.G.S., Mr. W. H. Crofts, and others ; and it is a real pleasure 

 to bear this testimony to the East Riding- workers. 



Our gratitude to the Chairman, Mr. Kendall, can never 

 be told, but is graven deeply in the hearts of all of us. 



J. H. HOWARTH. 



NOTE on YORKSHIRE LEPIDOPTERA . 



Melanic Variety of Phigalia pedaria at Doncaster.— This variety, 

 which has been gradually increasing- in West Riding localities since its dis- 

 covery (circ. 1880), has made its appearance in Wheatley Wood for the first 

 time this spring, when I took a specimen on 21st March. — H. H. Corbett, 

 Doncaster, 6th April 1902. 



NOTE on LINCOLNSHIRE FLOWERING PLANTS. 



Queries anent the White Thorn. — Can any brother botanist give me 

 an idea of the age which the White Thorn (Cratcegus oxyacantha) will attain 

 when it is permitted to grow into a tree and to run its natural course? Is 

 there any proof of the very general belief that the two-seeded variety 

 (C. oxyctcanthoides) is the old English Thorn, and that the common hedge- 

 row variety {C. monogyna), which is one-seeded, is a modern introduction 

 from abroad? I have looked through the literature on the subject, but can 

 find nothing about these two points ; and when asked for my opinion a short 

 time ago about these questions I had to acknowledge I had never met with 

 any evidence which was of any value. — E. Adrian Woodruffe-Peacock, 

 Cadney, Brigg, 15th April 1902. 



NOTE on YORKSHIRE PALAEONTOLOGY. 



Sac cam rain a carteri Brady in Yorkshire. — The occurrence of 

 this interesting foraminifer at two localities in Yorkshire seems worth 

 recording, though it is unfortunately impossible to indicate the horizon in 

 the carboniferous series to which the examples might be referred. The 

 first specimen was found in a pebble of limestone in a gravel-pit excavated 

 in the glacial deposits on the left batik of the river Wharfe, about fifty yards 

 above the wooden bridge in Bolton Woods. 



The other specimen- — the most beautiful example I have ever seen, 

 though I have collected the species from the well-known "Pea Post" of 

 Northumberland —is a block of yellowish limestone, presumably an erratic, 

 found on a wall in the village of Clapham. The colour and aspect of the 

 limestone, which is closely packed with Sctccammina, suggests that it has 

 undergone some dolomitisation ; and if that surmise be correct, then 

 perhaps some geologist with a more detailed knowledge of the Lower 

 Carboniferous rocks than I possess may be able to indicate its probable 

 horizon. — P. F. Kendall, Leeds, 7th June 1902.
