1. Noctilio rufusy Spix=i\^. amcrictmus or hpori'nns (L.)=iV'. unicoJo)' 
(Wied) j VespertiUa mastivus (Valil) = iV; dorsatus (Wied)=iV. leporinus 
(Gerv. Casteln. pi. 12. figs. 6 & 6«) is probably merely a variety : p. 670, 
2. Noctilio albivente7‘, Spix=i\^ qffinis (D’Orb. & GerA^)=iV'. leporinus 
(Gerv. Casteln. pi. 12. fig. C7>) = ?iV. ruhcr (Rengger). Very badly figured 
by Spix. Differing from N. rufus in size ; with or without a light dorsal 
band, as N rufus. Prof. Peters adds the measurements, p. 672, and figures 
the skull, fig. 1. 
3. Molosstts ursinusj Dysopes alccto (Temm.) = ilf. rufus (Geoffr.). 
The measurements are given, p. 676 ,* and the skull is figured, fig. 3. 
4. Molossus nasutus, Spix. Ears in form and size similar to those of 
M. ohsctcrus, not united, the distance between them being 2 millim. Tragus 
very small, with broad base, and with a very small pointed process at the 
lower end of the base. Nares as in 31. ohscurus. Margin of the lips swollen, 
without a trace of cross folds. Wing-membrane terminating at the last 
third of the tibia. Calcaneum Very long, extending nearly to the tail. Tail 
with eleven vertebrae, six projecting bej’^ond the wing. Ventral side of 
lumbar portion of the wing with a thick woolly fur, continued in a broad 
strip below the forearm, and descending on both sides of the metacarpus of 
the fifth finger nearly to the middle of the same. The ventral surface of 
the humeral portion is hairy near the throat only, whilst on the dorsal sur- 
face of the same portion of the wing a tapering band of thick hair extends 
to the middle of the forearm. A band of thin hairs, 6 millim. broad, runs on 
the other side of the forearm, the hair becoming thicker between the fourth 
and fifth fingers, and descends to the commencement of the third fifth of the 
metacarpus of the fifth finger. Brown, lighter below: p. 676 5 skull, fig. 4. 
6. Molossus fumariuSy Spix, identical with the preceding species: p. 679. 
6. Tliyroptcra tricolor, Spix, described by Basch, Nyt Mag. Naturvid. 
Christ. 1843, iv. 1. 
7. Prohoscidca ( = Emhallonura, Temm.) saxatilis, Spix = Vespertilio naso 
(Wied). Generally with two upper incisors on each side: p. 681. 
8. Prohoscidca rivalis, Spix, identical with the preceding species : p. 681. ’ 
9. Vespertilio hrasiliemis, Spix. Original specimen lost : p. 681. 
10. Vampyrus cirrliosus, Spix= Tracliyaps fidiginosus (Gray). Cfr. p. 27. 
11. Vampyrus hidens, Spix, belongs to the genus Lophostoma (D’Orb. & 
Gerv.). A detailed description is given : p. 686. 
12. Vampyrus soi'icmus, Spix. Cfr. p. 28. 
13. Pliyllostoma planirostre, ^f\yi—Ph.perspicillatmn (Geoffr.) is an Arti~ 
hem : p. 687. 
14. Glossopliaya amplexicaudata (Geoffr.) (Pall.) : p. 687. 
16. Piplxylla ccaudata, Spix. Young examples appear to have -f- molars, 
adult ones ' P* 587. 
Nycteris grandis, sp. n., Peters, Monatsber. Akad. Wiss. Berl. 1866, 
p. 361. Similar to N. ftdiginosa in colours and fut, but exceeding in size 
N. javanica. Ears as long as the head. The four upper incisors are 
three-lobed, and the second lower premolar is'scarcely one-third the size of the 
preceding, not compressed in its longitudinal diameter. From Guinea. 
(Allen). Professor Peters has demonstrated that the nearest 
ally of this American genus is Nyctophilus from Australia. lie thinks that.
