masonry on the central mound. A small fragment ot the 

 wall of this is all that remains. From this position the site of 

 the well-known pre-historic Lake Dwelling at Ulrome was 

 pointed out. Walking towards the beach, the party examined 

 the old lake bed. now exposed in the cliffs. This yielded a 

 number of interesting botanical and conchological remains — 

 relics of the primeval flora and fauna of the area. 



The botanists, and the general body of naturalists, spent the 

 day in continuing their investigations on the Mere at Hornsea, 

 and at the meeting which was subsequently held, it was reported 

 that important, and, in many cases, entirely new discoveries had 

 been made. 



A vote of congratulation and thanks was passed to Lord 

 Avebury by the delegates present, representing over 4000 

 naturalists in Yorkshire, for his efforts with regard to the Sale 

 of Plumes Bill. 



Reports of the work accomplished were given as follows : — 

 Vertebrate Zoology, Mr. R. Fortune ; Conchology, Mr. Harrison 

 Hutton ; Coleoptera, Mr. T. Stainforth ; Lepidoptera, etc., 

 Mr. G. T. Porritt ; Flowering Plants, Mr. J. F. Robinson ; 

 Mosses, Mr. J. J. Marshall ; Fungi, Mr. C. Crossland ; Diatoms, 

 Mr. R. H. Philip ; Geology, Dr. F. F. Walton and the Secretary. 

 Hearty votes of thanks to the landowners for the exceptional 

 facilities given were passed, a similar compliment being paid 

 to Mr. G. T. Porritt for presiding. 



The following reports on the excursion have since been 

 received from the officers : — 



Vertebrate Zoology. — Messrs. H. B. Booth and R. 

 Fortune write : — As might have been anticipated this section 

 was fairly well represented ; by far the greater part of the 

 members hailing from the W'est Riding. The Mere and its 

 surroundings proved the great attraction, the avi-fauna of 

 which appeared to them more like that of Norfolk than that of 

 a portion of their own county. 



Fourteen species of mamm.al? were identified, of which the 

 following were obtained : — Hedgehog, Mole, Common Shrew, 

 Stoat, Wood or Long-tailed Field Mouse, and House Mouse. 

 In addition to these, tw^o species of bats were observed at dusk — 

 a larger one and a smaller one — (probably the Noctule and the 

 Pipistrelle) , but they could not be secured for absolute identi- 

 fication.
