THE YOUNG 



NATURALIST, 



Of the Dermaptera only one species has 

 been recorded. 



107. FOBFicDiA AUEiCDLABU.— Earwig, Abundant 

 in the valley. 



Of the class Myriapoda there are various 

 species of centipides, millipides, &c., but 

 only one has been definitely named : — 



108. LiTHOBius FOETiCATUS. — Grassingtcn. 



We have thus arrived at the end of the 

 enumeration, an enumeration which is made 

 with the direct purpose of showing up in 

 strong relief the the great deficiencies which 

 characterise the present state of our know- 

 ledge of a fauna so interesting and so re- 

 markable as that of the upper basin of the 

 Wharfe. It is hoped that naturalists who 

 can in any way contribute towards the com- 

 pletion of an investigation, of which the 

 which the present paper is one of the mile- 

 stones marking its progress, will lose no 

 time in communicating their lists, or even 

 detached observations, records, or speci- 

 mens, to the officers of the Leeds Natura- 

 lists' Club, who will at all times be pleased 

 to receive them. For the information of 

 of such it will be useful to indicate what 

 extent of ground the district covers. First, 

 then, it may be stated that the upper part 

 of it includes the hills called Cam Fell, 

 Gush Knot, Penyghent, Fountains Fell, 

 High Mark, Buckden Pike, and Great 

 Whernside, at the foot of which are situa- 

 ted the hamlets and towns of Oughtershaw, 

 Yockenthwaite, Buckden, Starbotton, and 

 Kettlewell, on the Wharfe, and Litton, 

 Arnchcliffe, and Hawswick on the Skirfare. 

 On the right bank of the united streams the 

 district takes in Kilnsey, Skirethorns, Lin- 

 ton, Threshfield, Threapland, Thorpe, Burn- 

 sail, and Drebley : while on the left or 

 northern bank is included a wide range of 

 country, including Conistone, Hebden, 

 Grassington, and Appletreewick Moors, 

 together with the villages from which these 

 names are derived. The line which sepa- 

 rates Upper Wharfedale from the lower 



portion of the Wharfe Valley is drawn fron* 

 Stump Cross Caverns along the crests o< 

 Simon's Seat and Earl Seat hills; thence' 

 crossing the Wharfe, near Drebley, it is 

 traced along the water-parting on Burnsall 

 Fells and towards Cracoe. The boundary 

 in every other direction is traced along the 

 watershed lines which separate Wharfedale 

 from Malhamdale on the south, from Rib- 

 blesdale on the west, and from Yoredale 

 and Nidderdale on the north. — L.N.C. 



NOTES AND OBSERVATIONS 



The Alpine Swift in Northumberland. 

 — A specimen of that rare bird, the Alpine 

 Swift [Cypseles alpinus) , was shot at Alnmouth, 

 a few days ago, by Mr. Wm. Rogerson, of 

 Newcastle-on-Tyne. It measures 9 J inches 

 in length, and 21 inches across the expand- 

 ed wings. The specimen was named by 

 Mr. Hancock, of Newcastle-on-Tyne, and is 

 in the hands of Mr. Duncan, St. Andrew's 

 Court, Pilgrim Street, Newcastle, for pre- 

 servation. Murray's hand-book mentions 

 only five specimens of the Alpine Swift, as 

 having been taken in the British Isles. 

 Morris records five in England and two in 

 Ireland, though one of the latter was ob- 

 tained " some miles from land." It is new 

 to the North of England, the most northerly 

 occurrence hitherto being a specimen shot 

 in Norfolk, in 1831. Mr. Hancock's valu- 

 able catalogue of the "Birds of Durham and 

 Northumberland," enumerates 266 species. 

 The Crane {Grus cinerea), recorded since its 

 publication, and the present species bring 

 up the number to 268.
