142 NOTES—ORIGINAL AND SELECTED. Clausilia biplicata, Mont. in Essex.—Having to wait for a train at Purfleet on September 5th 1919, I devoted a short time to the investigation of a not very productive looking chalky bank in the vicinity of the railway station, when, to my great surprise, the very first shell to come to light was a specimen of C. biplicata. On further search I found that there was a fairly strong colony on the bank, living at the roots of the scanty vegetation and amongst the chalk debris. I know of no one likely to have introduced the species, and assuming it to be indigenous there, it is an interesting addition to Mr. Wilfred Mark Webb's "Non-marine Molluscs of Essex" (Essex Nat., x., 1897-8, pp. 27-48 and 65-81), and the locality is also a con- siderable extension of its known range in the Thames Valley.— F. B. Jennings. Hooded Crow and Great Grey Shrike in Epping Forest.—On 2nd November 1919, I identified a Hooded Crow (Corvus c. cornix) in Epping Forest. The Hoodie was flying in a leisurely manner, low down, over Fairmead Bottom. It crossed the Epping high road and was lost to view. A reliable observer who knew the district well, informed me that on rare occasions he had seen this crow in Epping Forest, but although I have studied the birds of the Forest for over ten years, this is the only occasion upon which I have seen one there. On 25th December 1919, while on Warren Plain, my attention was drawn by a light coloured bird, boldly perched on a medium sized tree. My thoughts immediately turned to the Lesser Grey Shrike which I saw commonly in Macedonia. On putting my binoculars on to the bird it was disturbed, but fortunately flew towards me, and as it passed the view I obtained left no doubt in my mind that I had seen the Great Grey Shrike (Lanius c. excubitor). The shrike settled on another tree, again on the highest bough in characteristic shrike manner, and finally dis- appeared into the private grounds of The Warren. On 11th January 1920, at the same place I again saw a Great Grey Shrike, probably the same bird. Records of this species in Epping Forest are remarkably scarce. Henry Do bleday, according to Miller Christy, had only seen one in the Forest. In
