*** Tail more or less elongated, extending one-half of its length 

 beyond the interfemoral membrane. Probably partly insectivorous. 



14. P. stramineus^ Geoif. 



15. P. Geoffroyi, the P. Mgyptiacus of Geoffroy-Saint-Hilaire, 

 a trivial name vrhich M. Temminck has ventured to change be- 

 cause the animal has since been discovered out of Egypt. We 

 would join him most cordially in testifying respect for the natu- 

 ralist to whom he has dedicated it; but we cannot agree with him 

 that it is " dans I'interet de la science" to set aside a name which 

 possesses the powerful claim of priority. 



\Q, P. titth(echeilus. Size rather less than the preceding species. 

 Snout short : eyes nearer to the nostrils than to the ears ; ears 

 short, notched near the apex of their posterior margin, trans- 

 versely wrinkled at their base, and bordered by a whitish line ; 

 nostrils distant, tubular; upper lip with two large tubercles, sepa- 

 rated from each other by a groove. Tail short, almost enveloped 

 in the interfemoral membrane, its slender point free : interfemoral 

 membrane notched. In the adult male the neck and breast are 

 rufous, the upper part of the body brown, and the under grey : in 

 the female these colours are modified by a mixture of olive. 

 Inhabits Java and Sumatra. 



17. P. amplexicaudutus, Geoff. 



18. P. marginatusy Geoff. The only specimen known to exist 

 is in the Paris Museum. On this the original notice was founded, 

 but it is in too imperfect a state for a detailed description. It has 

 so close an affinity to the P. titthoecheilus that M. Temminck has 

 been induced to suspect that it is identical with that species. 



This sketch of the characters of the new species of Pteropus 

 contained in the fifth number is abridged from the detailed 

 descriptions given by M. Temminck. It is to be regretted that he 

 should constantly abstain from giving in a specific phrase the 

 leading characteristics of each ; an omission which is calculated 

 materially to increase the difficulties of the enquirer, and is directly 

 opposed to the practice of the best Zoologists. But a far heavier 

 charge may be advanced against this Monograph, It is indeed a 

 ground of just complaint that of the five Pteropi figured, uo less
