MOLLUSCA, 



North Lincolnshire Mollusca. — While out in Newstead 

 parish, near Brigg, on the 9th January, my son Dennis and his 

 cousin, Tom Warner, took a dead Anodonta cygnea from a peaty 

 part of the Fairaway Drain. The valves are still held together 

 by the ligament. During the fourteen years I have been here 

 I have never seen this species living or dead. I have known its 

 habitats all my lifd, and it seems curious I have failed to find it.

North Lincolnshire Mollusca. — While collecting broken 

 shells from Thrush Stones to-day (nth January 1905), we took 

 two unusual forms, rubella 12045 ^^^^^ olivacea 12045. ^ have 

 only found the third band wanting thrice before in Lincolnshire. 

 The form 12300 I have never met with. Has anyone in Britain ? 

 To-day's most curious find was one specimen of rubella (12345), 

 creeping about as if it were mid-summer on the bank of North 

 Kilsey drain. — E. Adrian Woodruffe-Peacock, Cadney, Brigg.
