416 intermixed with a few Round Worms. I cannot understand why every bird should be thus infested. One young Blackbird, caught by my dog, which could only have been out of the nest some few hours, was equally full. There are great numbers of these birds about this year, and at present they are feeding out in the fields. This seems to be most injurious, aV dogs, horses, and cattle are thus exposed to the parasites. I enclose specimens taken from various Blackbirds and Thrushes, and should be very interested to know to which family of the Tænia they belong. I have examined a few Starlings and small birds, but in no instance have found them infested. If any readers of 'The Zoologist' have come across a similar occurrence I should be glad to hear of it, also if there is any means of reducing it.— (Mill Hill, Middlesex).
