At Birch Hall, the toads, while preferring the big reed beds, threaded their egg masses in all parts of the lake near the banks. At Theydon Bois the exodus of the young frogs took place in June, when it never seemed to me a very striking phenomenon, and young toads are seen on land at the same time; but, after the first heavy shower about mid-July (the 20th in 1915 and 1918, I note) young toads no bigger than bluebottles swarm every- where in astonishing numbers. At such times the people can hardly be convinced that the little animals have not been rained down from the sky. In a few days these swarming hordes have disappeared. 6.—NEWTS. It is difficult to understand how so many observations on Essex newts escaped my note book. For example, I cannot find any mention of the palmated newt,1 which is certainly common in some areas at least. Near Theydon, in winter, I used to find both the great warty and the smooth newts hibernating either under damp logs or deep in ponds. In captivity, smooth newts may live for many months, right through the winter, without being seen anywhere except deep in the water of the tank. A Forest common newt with a double tail lived with me for nearly a year; and a great warty newt from the same local- ity had, I noticed, the second toe duplicated on the left hind foot. THE BRITISH YELLOW WAGTAILS. By GULIELMA LISTER, F.L S. OUR common yellow wagtail is a regular summer visitor to the British Isles, and is distributed over the greater part of England from April to early September. In Essex it nests abundantly in low meadows and marsh land near the coast. Outside England it is comparatively rare, and appears to breed in small numbers only in west Holland, west France, and, perhaps, in Portugal, migrating in winter through the west of Europe to west Africa. It was first described by Willoughby and Ray in their "Ornithologia," published in 1676, where, 1 The Palmated Newt used to occur (and possibly still occurs) in a pond in the Forest at High Beach, Ed.
