336 Gr. E. Dobson — Brief Descriptions of five new Bats. [No. 4, 



but also, — in one genus especially, — quite as well developed as in the frugi- 

 vorous. 



In every species of the genus Taphozous, Greoff., examined by me, I have 

 found well developed post-orbital processes. In a skull of T. melanopogon, 

 Tern., before me, a long and slender post-orbital process of the frontal extends 

 more than half the distance between the frontal bone and the zygomatic 

 arch, forming nearly one-third of the entire circumference of the orbit. 



Post-orbital processes of the frontals are also found in the genera Mega- 

 derma and Nycteris. In the latter genus the post-orbital process may be 

 described as a triangular expanded lamina of bone, of which the base extends 

 from the sagittal crest to the maxilla ; in the former it is short and blunt, 

 and its base is perforated, as in Pteropus, by a supra-orbital foramen. 



In Yesperus pachypus, Tern., a small post-orbital process exists. 



The above examples show that in many species of insectivorous bats 

 post-orbital processes of the frontals are present. In no species, however, 

 have I succeeded in detecting corresponding zygomatic processes, as hi the 

 genus Pteropus. 



Beief descriptions op pive new species op Rhinolophtnp: Bats, — 

 ly G. E. Dobson, B. A., M. B. 



The following short descriptions of new species of Rhinolophine bats in 

 the collection of Chiroptera in the Indian Museum are intended as prefatory 

 to more detailed descriptions, to be published hereafter with illustrations. 



1. Rhinoiophtts Yunanensis, n. sp. 



Ears large ; antitragus separated from the outer margin by a deep, an- 

 gular incision. Nose-leaf large ; the horizontal horse-shoe shaped portion 

 concealing the upper lip as in Ph. luctus. The upper edge of the central 

 erect, anteriorly flattened, nasal crest meets, at the same level, the upper 

 edge of the posterior vertical membrane. Lower lip divided by a single ver- 

 tical incision. Wings from the ankles ; tail contained within the interfemo- 

 ral membrane, with the exception of the extreme tip ; interfemoral mem- 

 brane cut square behind, or slightly concave. 



Length, head and body, 2'7 inches ; tail 09 ; ear (anteriorly) 1"0 ; nose- 

 leaf 07 ; forearm 2'2 ; tibia 11. 



Sab. — Hotha, Yunan ; collected by Dr. Anderson during the Yunan 

 expedition.* 



* Other new species of bats obtained by Dr. Anderson during the Yunan Expe- 

 dition have been shortly described by the writer in the Proc. As. Soc. Beng. for Sept. 

 1871.
