" elongata, antibrachium longitudine superante, apice obtusiusculo : 2. 

 " Pkc. brevimanus ; Plec. vellere supra rufo-fusco, subtus albescente; 

 " auriculis oblongis, capite baud duplo longioribus ; trago ovato-lanceo- 

 " lato ; Cauda aatibrachium longitudine cequanti, apice acuto." In ad- 

 dition to these distinctive characters others are suggested by a comparison 

 of the dimensions of each of the species appended by Mr. Jenyns to his 

 descriptions. They differ also in absolute size, the expansion of the 

 flying membrane in the Plec. aurilus exceeding that of the Plec. brevi- 

 manus by one half; and in colour, the former being brownish-grey 

 mixed with dusky, which is merely of a somewhat paler tint below, 

 while in the Plec. brevimanus the upper parts have a reddish tinge, which 

 presents a marked contrast to the yellowish white of the under surface. 

 The only specimen of the latter which has yet been seen was found ad- 

 hering to the bark of an old tree at a distance from any habitation, which 

 would appear to indicate that its habits differ from those of the Plec. au- 

 ritus, a resident altogether in buildings, and taking shelter more parti- 

 cularly within the roofs of dwelling-houses. Mr. Jenyns concludes his 

 notice by stating his suspicion, founded on a memorandum made by him 

 respecting a specimen not now in his possession, that a third, and much 

 larger, species of long-eared Plecotus exists in England. 



Mr. Bell has given us, in his " Description of a new species of Pha- 

 langisfa" a detailed account of the Phal. gliriformis, the specific cha- 

 racter of which will be found at page 502 of our present volume. In 

 form it resembles the common Dormouse, than which it is somewhat 

 larger, broader, and more depressed ; and the habits of the two animals 

 are also extremely similar. The Phal. gliriformis is nocturnal, remain- 

 ing asleep during the whole of the day, and coming forth late in the 

 evening, when its movements are rapid and vivacious. It feeds on nuts 

 and other similar nutriment, sitting up on its hind quarters, and carrying 

 its food to its mouth by means of its fore paws, which it uses as hands. 

 It has not, however, been observed to hibernate like the Dormouse, nor 

 had it, up to a very late period in the year, evinced any disposition to 

 prepare a winter bed, although wool and other soft substances were pur- 

 posely placed within its reach. Two living specimens in the possession 

 of Mr. Morgan have furnished the materials for Mr. Bell's detailed de- 

 scription and account of the habits. Both of them are females, and one
