the Lower Amazons. 271 



18. DicHdurus sontatus, Peters. 



S. 38, 165. Para. 



"Caught in tlie old io\vn."—E. S. 



These specimens are of great interest, <is no example of 

 D. scutatus has been recorded since Peters described the 

 species in 1869, and its locality was unknown. The species 

 is evidently quite distinct from D. alhus by its smaller size 

 and less complicated caudal gland ; but without spirit- 

 specimens the differences in this latter respect are not easy to 

 appraise. 



The skull agrees with that of D. alhus in the extension of 

 tiie palate behind the level of the posterior molars. 



19. Depanycteris Isabella, gen. et sp. n. 

 cJ . 73. Manacapuru, Rio Solimoes (^. /S/ie^A/a^^). Tt/pe. 



Depanycteris, gen. nov. 



Allied to Diclidurus. Colour pale brown, not white. 

 Ears about as in Diclidurus ; no trace of the enormous lobe 

 on tiie tragus found in Cyttarops. Tiiumb not so remarkably 

 abbreviated as in Diclidurus and possessing a distinct claw. 

 Hind limbs with the feet markedly longer in proportion to 

 the tibiae, the distance from the base of the calcar to the tip 

 of the claws more than half the length of the lower leg, while 

 it is decidedly less than half in Diclidurus. Groove along 

 inner side of tibia shorter, more open, and less sharply defined. 

 Tail-tip in male without any horny capsule, although there 

 is apparently a structure somewhat similar to that of the 

 female of Diclidurus. 



Skull in most respects similar to that of Diclidurus, but 

 the palate is deeply emarginate behind — to the level of the 

 front edge of m^, — while in front it is also more broadly 

 excavated. Basial pits well defined. 



Teeth about as in Diclidurus. 



Genotype. D. Isabella, sp. n. 



This relative of Diclidurus is in general a less highly 

 specialized form than that is, its brownish colour, more 

 normal pollex, and less developed caudal glands all being 

 evidence in this direction. It has no special affinity with 

 Cyttarops. 



Depanycteris Isabella, sp. n. 



Size about as in Diclidurus scutatus. Colour very similar 

 to that of Mesophylla macconnelli, the head and shoulders
