Porritt, and he informs me that the species is one of the Cram- 

 bites, Ephestia knhniella. The species was first taken in our 

 county by the Rev. C. D. Ash, at Skipwith in November 1898, 

 and first recorded as British from Stoney Stratford in Bucking- 

 hamshire, in 1887. In all propabihty it has been introduced 

 here, but there is no doubt about it being plentiful now. — -B.

Sterrha sacraria at Qrang-e-over- Sands. — Mr. W. 



Shackleton of Bradford, recently shewed me a beautiful male 

 specimen of this rare geometrid, which he caught at Grange- 

 over-Sands in early September 1906. According to Mr. South, 

 six or seven specimens were obtained in Lancashire in 1867, 

 and it is interesting to note its occurrence again in that county 

 after the lapse of thirty-nine years. Very few records have 

 been made of this North African species in Britain since 1874. — 

 B. MoRLEY, Skelmanthorpe, Huddersfield, March 3rd, 1909. 

 A small number of specimens have been taken in the extreme 

 Southern Counties during the past few years, several of which 

 are now in my collection. — G. T. P.

 Paludestrina jenkinsi in Airedale. — In October last 

 year, Mr. C. T. Cribb, of the Vicarage, Shipley, found, in the 

 river Aire, above Shipton, a number of Paludestrina jenkinsi 

 along with other species, on Elodea canadensis. The occurrence 

 rence of this species is worth recording, as it is an inhabitant 

 of the coast, or of the streams that occur near the coast. Yet, 

 by some means or other, it is getting transported to various 

 parts of our inland counties. It was recorded from the river 

 Spen at Cleckheaton, about three years ago, and now from the 

 Aire Valley, so high up as Skipton. It would be interesting 

 to ascertain exactly the cause for this sporadic appearance up 

 and down the country, it having been turned up in several 

 other Midland Counties. — F. Booth.

Note on Transported Lias near Filey. — Those who have 



followed the elucidation of the Yorkshire coast geology, will 



remember that certain patches of blue clay which occur in the 



Boulder-clay at Filey were described by Judd as " Middle
