Show 466 MR. BOULANGER ON IGUANA TUBERCULATA. [Nov. 3, pearl-like excrescences which are placed at each corner of the bill. They form a triangle, of which two are of a very fine pearl-like blue, and the third of a pale buff-colour. When the bird opens its mouth the buff-coloured pearl is found to be the real corner of the bill, whilst on each side is a blue pearl. The beak itself is of a shining black colour, the head is grey, the throat lighter. The breast is a greyish buff, gradually melting into the yellowish white of the belly. The back is olive-green, and the tail-coverts bluish green. " The egg is white. The nest, as will be seen, has no roof to it, as have the nests of most Australian Grass-Finches, but is an open construction of some dried weeds and grass, and was placed in a little wooden box, of which the front was open. " Five little birds came out, and at the age of about three weeks, I think, flew out, and were very active and independent from the beginning. The old birds have fed them entirely on canary-seed and white millet. They used no ants'-eggs or anything of that sort. "They seem to be perfect vegetable-feeders. How the plumage of the young birds changes I hope to be able to let you know later." The Secretary exhibited, on behalf of Prof. E. C. Stirling, of the University, Adelaide, C.M.Z.S., an original water-colour drawing of the new Australian Mammal, Notoryctes typhlops, prepared from a pencil-sketch taken from life. Prof. Stirling had written as follows:- " This drawing represents the animal in an observed attitude, and shows one or two of the characteristics which I have described. The ground is the red sand so prevalent in the interior, and is coloured from a sample I brought down. The ' tussocks' are those of Ariodia irritans, the Porcupine-Grass or spinifex of the Interior, some of the tussocks being in flower. For the sake of the distance and perspective they have been represented proportionately too small; but the sketch conveys very well the idea of the kind of country the animals are found in, i. e., bare sand, with scattered tussocks of this pointed grass." Mr. Boulanger exhibited an Iguana with reproduced tail, and made the following remarks :- " The specimen of Lguana tuberculata, from Curasao, which I exhibit, was received a few days ago at the Natural History Museum. It is interesting for having the tail regenerated-a somewhat unusual occurrence in this well-known Lizard, and especially for the remarkable appearance of the restored portion. The caudal scales in Lguana are disposed in verticils, but on the regenerated organ they are arranged quincuncially ; and instead of the black annuli we have a black dorsal stripe. This stripe begins at the base of the regenerated portion, a little to the right, at the posterior edge |
