the district explored being within the magnificent Harewood Estate, including the 
North-Kastern portion of the Park. A. succobolus, new to science, was found on 
that occasion. Of course, mid-May is not the season for a crop of fungi, but a few 
Spring species are certain to be met with by careful investigation of the ground. 
VERTEBRATE ZOOLOGY.— The Vertebrate Section will' be officially 
represented. 
Mr. R. Fortune writes ; — The district is exceedingly ricli in bird life. The 
Green and (ireat Spotted Woodpeckers are to be found, also the Tree Creeper and 
most Northern woodland species. Three species of Owls, Hawfinch, Red Flycatcher, 
Gold Crest, etc. Owing to strict preservation, Hawks are not tolerated. A small' 
and gradually diminishing Heronrv may be re seen in the Park. On the lake 
several pairs of Great Crested Grebes and a fine herd of Whooper Swans mav be 
seen, and in an enclosed lake are a number of ex^emely interesting wild fowl. With 
regard to the smaller mammals very little has been done in working them out. 
Information, especially with regard to the Bats, is particularly desired No records 
appear to have been published with respect to the Fishes and Reptiles. 
CONCHOLOGY.— The Conchological Section will be officially represented. 
Land and Freshwater MuUusca. — Mr. W. D. Roebuck writes : — There is 
but little known, the geological formation being an unfavourable one. Roadsides 
in and by the Park have yielded Hygroniia rnfescens, Hvalinia cellaring Pyramidula 
rotundata. Pupa cylituiracea, etc. Sphyradiittn edentulnm was found at Harewood 
by Mr. W. Nelson. Cochlicopa lubrica has occurred at Castley and Pool Bank, 
P. rotundata also Hygrofnia hispida at Netherby and var. subriifa at Pool, 
H. rnfescens is abundant on Pool Bank. Helix hortensis at Pool and common at 
Weeton, H . nemoralis occurs on Pool Bank and at Weeton, Hyalinia helvetica 
occurs at Pool Bank and at the south end of Arthineton Viaduct, H alJiaria at 
Weeton and //. cellaria at Arthington. Of freshwater shells Limtura peregra occurs 
in various waters, and Platto^bis spirorbis at Fool, and Mr. W. Nelson took 
PI. albus commonly at Hollin Lake, near Wike. 
The fish-pond sliould be searched for water-shells and the woods for woodland 
forms. A visit to the backwater near Carthick Ford might be worth while, and 
there are holocene fossils on the Wharfe bank not far off. 
ENTOMOLOGY. — The Entomological section will be officially represented. 
Lepidoptera. — Mr. W. D. Roebuck writes : — The only records are as follows : 
Colias edusa, J^a/iessa cardtii, Polvommatus icaru<:, Macroglossa stellalaru?n and 
Anisopteryx irscularia have occurred at Arthington, Chortobius pamphilus at 
Dunkeswick. Abraxas grossul riata. Xvlophasia 7urea, Mamesira persicaria and 
Plusia c/nysiiis^i Weeton Bridge, Camptooratnma bilineata at Pool and Gonopteryx 
libaitix at Pool Bridge, Oigyia aniiqtia and Hvherma au) antiaria at Harewood 
and UraPleryx sanihucata in the Park. This shows how urgent is the need for 
further records, even of the commonest species. 
Diptera — Three ':])ecies only are on record : Ha:tnatopota pluvialis (Cleg) at 
Weeton, Mesembrina meridiana and Hovialo7>i^ia bre^is at Pool. 
Neuroptera. Nothing known. 
Coleoptera. Nothing on record. 
Hymenoptera. — The only records are of a sawfly, 7 richiosoma beiuleti, at 
Arthington : a fossor, Blepharipus dimidiatiis. and two humble-bees, Bombus 
lapidarius, B. hortorum and Chrysis ignita at Harewood. 
In order that an early account of the excursion may appear in the "Naturalist," 
notes and reports should be forwarded before May 20th, to the Secretary of the 
Y.N.U., the Museum, Hull.
