An asterisk (*) before a species shews that the specimen 

 was found ahve ; a dagger (f) that it was found only in a very 

 young state. 



It will be noticed that by far the majority of species are 

 bivalves, which is what we should naturally expect on a sandy 

 beach. At Scarborough, the alga-loving univalves predominate. 

 The absence of such familiar species as AcmcBa virginea, 

 Helcion, Eumargarita, Littorina ohtusata, Skenea planorhis, 

 Natica alderi, and all species of Odostomia and allied genera 

 were particularly noticeable. 



Vertebrate Zoology. — Mr. Wm. Hewett writes : — Not 

 many species of mammals were seen. There was an abun- 

 dance of hares and rabbits, and also one weasel, and at the 

 evening meeting on Saturday, Mr. Thomas Audas reported 

 having seen a badger. 



The majority of those present at Monday's excursion took 

 the opportunity of observing the wondrous bird life along the 

 cliffs from Buckton to Bempton, where the Guillemot, Razorbill, 

 and Puffin were in countless numbers, along with the Cormorant, 

 Herring Gull, and Kittiwake. The methods of working by the 

 egg-climbers, of which there were four parties operating, also 

 proved of great interest. 



I saw a single Wheatear at Buckton, and another at North 



1912 July I.
