The two following belong to the tribe of Horse-shoe Bats, Rhino- 

 lophina : — 



5. Aquias. 

 Ch. gen. — Prosthema permagnum, complicatum, parte posteriore lan- 

 ceolate erecta, tribus magnis cellis utrinque ; processus centralis 

 compressus margine anteriore lato, expanso, foliaceo, lobato, me- 

 dio basi convexo ; ferrum equinum anterius magnum simplex ex- 

 pansum, centro inciso, setosum ; labium inferius duabus verrucis 

 triangularibus in medio notatum. Mammce in pube distinctse. Alee 

 a digitorum basi. 



Nose-leaf very large, complicated ; hinder part lanceolate, erect, 

 with three large cells on each side in front ; central process com- 

 pressed, with an expanded broad foliaceous lobed front margin, and 

 with a convexity in the front of its base edge, formed by a diverging 

 ring on each side in front. The front horse-shoe large, simple, ex- 

 panded, nicked in the centre, very hairy; lower lip with two trian- 

 gular warts in the centre. Pubal teats distinct. Wings from the 

 base of the toes. 



This genus may be divided into two sections : — 



1 . The interfemoral acutely produced ; tail as long as the shin 



and foot. Rhinolophus luctus, Temm. 



2. Interfemoral truncate ; tail as long as shin. R. trifoliatus, 



Temm. 



We have a specimen in spirit in the Brit. Mus., which differs from 

 Temminck's description of Uh. luctus in several particulars, but these 

 differences may arise from his description having been taken from a 

 dry specimen. 



6. Rhinonicteris. 

 Ch.gen. — Prosthema breve, erectum, cella utrinque, et altera anteriore 



in medio basi ; processus centralis compressus, anterius planus ; 



ferrum equinum emarginatum, concavum ; inter nares culmen fim- 



briatum. Aures magnae. Alee a talo. Dentes incisores f incisi ; 



superiores distincti ; labium inferius triangulari tuberculorum mole 



scabrum. 



Nose-leaf short, conical, erect, with a cell on each side and one 

 in the centre of the front of its base ; the central process compressed, 

 flattened in front, and without any pit beneath; the horseshoe 

 deeply nicked, concave, with a longitudinal anterior fringed ridge, 

 ending in a pit behind, between the nostrils, and with a ridge over 

 the nostrils on each side. Ears large, separate. Tragus none. Pubes 

 — . Wings from the ankle. Cutting teeth ^, notched ; upper 

 distinct ; lower lip with a triangular group of small warts in front. 



Type, Rh. aurantius = Rhinolophus aurantius. Gray ; Eyre's Cen- 

 tral Australia, i. 406. t. 1. fig. 1.
