Entomology. 



No attention has been paid to insects as yet. Carabiis nitens is- 

 common at 1620 feet on Birkdale Tarn moss (W. Eagle Clarke), and 

 Selenia lunaria has been taken near Muker by Mr. S. L. Mosley. 



Conchology. 



Mr. W. Denison Roebuck, F.L.S., Leeds, observes that the list of 

 Upper Swaledale Mollusca (see Naturalist for August, 1890), includes 

 so far thirty-five species, only two of which — Lii/incea trimcatula and 

 Ancylus fliiviatilis — are aquatic forms, the swift and turbulent character 

 of the Swale and its tributaries being unfavourable to a longer list.. 

 It is strange, however, that L. peregrahzs not yet occurred. The seven 

 slugs are the ordinary forms, while the montane and calcareous- 

 character of the district is shown by the abundance of Cla2isilia dubia, 

 JBaiea, H. arbustorum and H. nipestris. Other species present include- 

 Helix sericea, w^hich is well distributed and very common, Azeca^ 

 Biilimiis obscurns, Vertigo pygincea, Carychiuin, Helix pulchella, H. 

 rufescens, and eight species of Zonites. Of the species not recorded 

 search should be made for Limax viaxiimis, both Succinece, Helix 

 C07icinna, H pyg/ncea. Vertigo edentula, H. fiisca, H. aaileata, etc. 

 The road-sides from Isles Bridge upwards to Keld, and the limestone 

 scars at Gunnerside and elsewhere are prolific hunting grounds, while 

 the luxuriant and well-sheltered woods of the romantic gorge in which 

 the Swale dashes over the beautiful Force of Kisdon, and the scars 

 which border the river north of Keld, have never been thoroughly 

 investigat'ed, and the woods might even be found to produce not only 

 the above, but such species as Helix lamellata, Pupa ringens and 

 Clausilia lauiinata, none of which are on record. 



Vertebrate Zoology. 



The mammals known include the Red Field Vole (E. R. Waite)^ 

 Water Shrew (S. I^. Mosley), Water Vole, Squirrel, &c. The Reptiles 

 include the Lizard and Slowworm (Viper absent), and the Fishes are 

 Loach, Minnow, Bullhead, Eels, and Trout. The Oxnop Beck Trout 

 have been described by Day as distinct, under the name of Salmo- 

 fario swaledalensis. 



Mr. J. G. Goodchild writes that the birds are those common tO' 

 nearly all the upland areas of the North of England. The Buzzard a 

 few years since, and the Peregrine, the Raven, the Merlin, and 

 occasionally the Short-eared Owl bred, not uncommonly, among the 

 moors. The Curlew, Dunlin, Common Snipe, and Golden Plover 

 are common in the breeding season. Amongst the smaller birds the 

 Grey Wagtail, Dipper, and Ring Ousel are common. Mr. S. L. Mosley 

 has found the Dunlin's nest, and noted Ravens, a species which has- 

 bred in the dale within recent years. 



Micro-Zoology and Micro-Botany. 



Mr. W. W^est, F.L.S., has recorded (Nat., Aug. 1889, p. 246} 

 various species of Algae found on Birkdale Tarn moss, at 1620 feet, 

 including several uncommon ones, and would be glad for members to- 

 send him tubes containing water from permanent pools on the moors..
