Miscellaneous, 397 gascar, and whose zealous efforts have very materially forwarded our knowledge of the ornithology of the East-African Archipelago. The genus Ti/las is nearly aUied to HypsipeteSy but differs in the beak being decidedly stronger, broader, and more inflated ; in the longer wings, which in Hypsipetes do not reach to the middle of the tail; in the tail being proportionally shorter; and in the rictal bristles being much more developed. The under tail-coverts are very long. The iris is yellow — a colour not found hitherto in the genus Hypsipetes. The whole system of coloration is different from that of the latter genus. MISCELLANEOUS. Notice of a new Species of Cynoipterns from Moriy Island, By Dr. J. E. Gray, F.R.S. The British Museum has lately received from Mr. A. B. Wallace two interesting specimens of a fruit-eating Bat from Morty Island, col-lected in 1861, which appears not yet to have been registered in the Catalogues. I therefore subjoin a short specific description of it. It is easily known from all the other species by the extraordinary length of its tail ; indeed, it seems to form a section or subgenus apart, that may be called TJronyctei'is. Cynopterus (Uronycteris) alliventer. Tail elongate and free, produced beyond the narrow interfemoral membrane. Nostrils much produced, tubular, and far apart. Brown above, with greyer base to the hairs. Face and throat only slightly hairy, grey ; side of the neck and breast yellow-brown ; side of the body brown ; chest and middle of the belly white ; the wing browur Hab. Morty Island. The length of the fore-arm 2 inches ; length of tail (dry) nearly I inch. The wing-bone on the upper surface of the wings of both speci-mens is marked with some irregular white spots ; these may be only accidentally or even artificially produced in the process of preserva-tion, or by carriage, as the spots on the two sides of the same wing are mdike, and those of the two specimens dissimilar. On the Larvce of Hypoderma. By F. Braxjer. In August 1860, the author communicated to the Zoological audi Botanical Society of Vienna some observations on the change of skin in the larvae of Hypoderma. He now calls attention to the agree-ment of his observations with those published by Leuckart on the larvae of the MuscidcBy which is especially important, as the investi-gations were quite independent of each other. In the CEstridcB change of skin was said to take place by Neuman and Joly j but neither of these authors had witnessed this pheno-
