 adds that the wetness of the present season is favourable to adding 

 materially to the list of land shells, of which very few were observed 

 on the occasion of the Union's previous visit to the same ground on 

 a very sultry day in 1880. 



Vertebrate Zoology. 



Mr. F. Boyes writes : — Some portions of the district to be visited 

 have lost much of their interest since the introduction of the steam 

 plough, and many hundreds of acres of peaty moorland and sandy 

 desert-like areas have been changed into cornfields, thereby consider- 

 ably altering the character of their fauna and flora. The large Rabbit 

 warrens (at one time the summer-house of the Stone Plover, the Red- 

 shank, the Snipe, and the Peewit, as well as the Nightjar and numbers 

 of Stock Doves, which latter nested in the Rabbit holes), have now 

 become almost deserted by these birds, and the ground is nov/ tenanted 

 by the ordinary well-known denizens of cultivated districts. To the 

 same cause is attributable the disappearance of the Lizard, the Adder, 

 and numerous other creatures peculiar to similar unreclaimed oasises, 

 but it is amongst the insects where the greatest change has been 

 effected ; it was there where our rarest species were formerly to be 

 found, now almost deserted by them in consequence of the alteration 

 of flora. But though we regret the loss of so much that is peculiar 

 and interesting there still remains a fauna well worth searching for and 

 investigating, amongst which may be mentioned the Crossbill, Jay, 

 Magpie, Nightjar, Heron, Turtle Dove, Woodpeckers (Green and 

 Great Spotted), Stock Dove, Wood Wren, and probably Stone Curlew, 

 but by far the most attractive bird likely to be seen is the Sand Grouse,, 

 which at present is within the district to be visited in large numbers, 

 though somewhat erratic in its movements from place to place. 



Micro-Zoology and Botany. 



No attention appears to have been paid to this branch of research, 

 and it is to be hoped that microscopists will avail themselves of the 

 opportunity for investigation.
