Essex Naturalist, ix. 49 and x. 56), It was reported that owls 



continued to increase. Kestrels, sparrow-hawks and magpies 



remained about constant. Small birds were very numerous, 



and the gold finch is on the increase, and has nested in regularly 



increasmg numbers. 



MOLLUSC A. 



Ostrea Angulata, an introduced Mollusc, at Southend. 

 — In 1903, Dr. C. B. Plowriglit sent me specimens of Ostrea 

 ■angulata attached to periwinkles which had been bought in the 

 Lynn market. 



In October, 1903, I visited Southend and found full-grown 

 specimens attached to stones, mussels, and oyster shells. They 

 were picked up, dead and alive, on the tide mark from Southend 

 •gas works to Shoeburyness. The thickness of the shell makes it 

 more liable than other oysters to be rolled about by the water, 

 and hence many of them were so worn they could only be dis- 

 tinguished from oval stones by their regular black and white 

 banding. 



On making enquiries I was fortunate enough to meet a 

 Southend dealer who supplied the Lynn market. He informed 

 me that this oyster was introduced from Portugal for cultivation 

 in the Thames Estuary, but they were considered too small, and 

 so their owners "loped 'em overboard " ; but again, unlike other 

 oysters, the spat settles readily, so that they are now well 

 ■distributed. 



As this species was offered for sale in the Southend shops, I 

 thought it unnecessary at the time to call any attention to its 

 occurrence. — T. Fetch, B.Sc, Leytonstone. 



Testacella Haliotidea, Drap., at Colchester. — Dr. 



Chichester yesterday brought me in a specimen of this subter- 

 ranean carnivorous slug, which had been found in his garden at 

 Crouch Street, Colcliester. This is the only Essex example that 

 has come under my notice. — Henry Laver, F.L.S., March

Arion Intermedius Norm. (A. minimus Simroth) in 

 Epping Forest. — This slug is not recorded as an Essex species 

 in Mr. Wilfred Mark Webb's " Non-Marine MoUusca of Essex"
