Bustard, Red-breasted Snipe, Whiskered Tern, Mediterranean 

 Black-headed Gull, Brunnich's Guillemot, White-billed 

 Northern Diver, Levantine Shearwater. It may also be 

 remarked of Tengmalm's Owl that out of the twenty known 

 British specimens no fewer than twelve have occurred in this 

 county, and three of these Mr. Clarke has had the personal 

 pleasure of adding on the most imquestionable authority. In 

 addition to this, numerous occurrences of rare species — which 

 have hitherto remained unpublished — now appear for the 

 first time in print.
