Falconer : The Spiders of Yorkshire. 257 



In many cases in the following list the absence or paucity 

 of records will probably be found to be due to the areas in 

 quest on having been imperfectly investigated. As some 

 indication of the wealth or poverty of the county's araneidal 

 fauna, the numbers placed after the names of families and 

 genera {e.g., Fam. Drassidce, 7-22; genus Drassus, 4-8), denote 

 the proportion of Yorkshire to British species. All entries 

 other than my own, except where necessary, are distinguished 

 by the collector's initials, or their source indicated, the abbrevia- 

 tions employed being : —

The Bempton Peregrines. — On May 13th, when climbing 

 commenced at Bempton, the Peregrine Falcons had two eggs 

 in the old eyrie. John Hodgson, who went down to look at 

 them, reports that they looked old and dirty. There was no 

 more climbing at that end of the cliffs and when the eyrie was 

 again looked at on 24th June the young had flown. Whether 

 both got safely away it is impossible to say, as the climbers 

 purposely left the place absolutely quiet, and their ordinary 

 climbing did not extend beyond Hartley Shoot. — E. W. Wade. 



Mason Bee at Whitby.— During early June I frequently 

 noticed a specimen of this bee in my garden, and later in the 

 month found a cluster of mud cells built between the window 

 frame and sash of a room, the window of which facing south, 

 having been left slightly open. There were 25 or 30 cells in 

 two layers all closely sealed, and each containing a ball of 

 honey and pollen, on the top of which a small grub attached 

 by its posterior claspers was feeding. Being obliged to remove 

 the colony they were placed on a wa^l under a plant pot, but 

 enemies were evidently attracted, perhaps by the strong odour 

 of the honey, and have prevented any further observation. —
