the 'sixties.' 



All four British species of Polypodhim are common, 



Polypodium dryopteris and P. phegopteris both occur below 



Keld. 



Allosorus crispus is locally abundant on upland crags, where no 

 calcareotis matter is present. It never grows on limestone. 



Cystopteris fragilis is one of the commonest ferns on dry crags, 

 old walls, etc.

Polystichum aculeatum is yet abundant. 



Lastraea oreopteris is very abundant locally, especially on the 

 sheltered parts of the fell-sides. 



Asplenium viride is abundant in limestone joints, deserted lead- 

 mine levels, etc. 



Asplenium trichomanes has a wider habitat. 



Asplenium adiantum-nigrum occurs very locally ; it is found on 



some of the crags near the dale-head ; also below Gunnerside.

 Hymenophyllum tunbridgense has been met with near one of 



the fosses in Swaledale.

Seal on Coast of Durham.— A Phoca gryphus was picked up on March 17th, 

 1887, in the sea between Hartlepool and Seaham ; it weighed 35 stone, was 8 ft. 

 long, and nearly 6 ft. in girth.— J. W. L. T. Fawcett, The Grange, Sallley. 



Natterer's Bat near Thorp Arch.— I am pleased to be able to record an 

 occurrence of Natterer's or the Reddish-gray Bat ( Vespertilio nattcreri) for this 

 district. On the nth inst., walking from Thorp Arch Station towards Walton, 

 I found the bat lying on the road, but recently dead, as it was quite warm and 

 bleeding at the mouth and nose. On opening the Bat I found the front of the 

 skull smashed as though it had flown against, or been struck by something. It is 

 a female and weighed 115 grains.— Edi;ar R. Waite, The Museum, Leeds, 

 2 1st July, 1890.
