 Dolini. (lonoa Musoura. — Type of ihe species. 



Diagnosh. — A small « Nyctinomus » (sensu lato, as in 

 Dobson's Catalogue ) , with -^ incisors , g premolars , and very 

 strong supraorbital crista; with large gular sac, the front margin 

 of the ears quite straight, the fifth metacarpal ecjual to about '^l^ 

 the lengtli of the third; and inhabiting Sumatra. — Forearm 38 mm. 



Details and Remarks. — The new Sumatran species of 

 ^lorinopterus to he described here belongs to a small section 

 of Uie genus which till now was known onlg from ihe 

 Mascarenes, Madagascar, and Port Natal. Thk section, cha- 

 racterised by the species having -^- incisors, -^ premolars, and a 

 gular sac, numbered hitherto two species, M. acetabxlosus Connii. 

 (Mascarenes, Madagascar, Port Natal) and M. jugular is Pet. 

 (synonym: Nyctinomus alhiventer I)ol)s. ; Madagascar) ( ' ). 

 M. acelabulosus lias a distinct emargination in the front margin 

 of the ear-conch, Ixdow the tip (see figure in M. 15. Akad. Herlin 

 1881, plate, lig. I), whereas in M. jugular is the front margin 

 of the ear is straight (1. c. fig. !2). M. doriae is in this as in 

 most other respects similar to M. jugularis, and on a comparison 

 with this latter species the subjoined description is ])ased: — 



M. do7^iae accords with M. jugularis, — in the general 

 shape of the skull; in the numl)er and structure of the teeth: in 

 the presence of a gular sac; in lia\iiig the front margin of the 

 ears quite straight; in shoi't : in all the more important cranial, 

 dental and external characters, even in ihe general size.
