them. Dr. Horsfield divides the Javanese species into two 

 sections ; the first having the superior lobe of the nasal mem- 

 brane erect and lanceolate — the second having above a trans- 

 Verse membrane, stretching forward as a small arch. 



The species included in the first section are R. qffinis and 

 minor: those of the second are nobilis and larvatus above 

 characterized, vulgaris, deformis, and insignis. 



Vespertilio Temminckii. V. capite cuneato supra lateri- 

 busque planis, auriculis capite brevioribus oblongis rotundatis 

 margine exteriore parum excisis trago elongato falcato, vellere 

 sericato pilis brevissimis supra fuscis subtus sordide-flavis la- 

 teribus capitis corporisque nitore dilute rufescente. 



Of this species, peculiarly characterized by the shortness of 

 its fur, a detailed account is given ; with concise notices of the 

 following; allJavanese: — V. adversiis, Hardwickii, tralatitiusy 

 imbricatus, and pictus: all of which, except the last, are new. 



Passing now to a very different family of Mammifera, we 

 have to notice Dr. Horsfield's recent establishment of a sub- 

 genus of Ur.ms, from the U. malaymius, described in the fourth 

 number of this work, and a new species from Borneo, at pre- 

 sent exhibiting in the menagerie at the Tower*. His memoir 

 on the subject is contained in the sixth number of the Zoolo- 

 gicalJournal; but the first species discovered of the new group 

 having been described in the Researches, a notice in this place 

 will be most appropriate. 



To the new subgenus Dr. H. applies the name of Helarcfos, 

 from ehr) {calor Solaris) and ocpxrog (iirsi/s), its range appearinor 

 to be limited within a few degrees of the equator. The fol- 

 lowing extracts from his detailed subgeneric character will be 

 sufficient for our present purpose.

• Whilst this article was passing through the press, a living speciinen of 

 Umu.i malai/finux itself has been received from Sumatra by Sir Stamford 

 Raffles, and consigned jjrovisionally to the above menagerie, where it may 

 be compared with its congener, and the Talidity of Dr. Horsfield's si)ecific 

 distinction of the two satisfactorily ascertained.
