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.

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-
