[213] Natalus stramineus.
[214] Furipterus horrens.
[215] Saccopteryx bilineata.
[216] In one species, Saccopteryx plicata, from Costa Rica, of which Professor Peters makes his genus Balantiopteryx, the sac is placed in the middle of the shoulder membrane. In this species, also, the facial part of the skull is inflated on each side. In S. canina and its allies the sac is in the margin of the membrane. These form the genus Peropteryx of Professor Peters.
[217] Other described species of the genus are Saccopteryx canina, from Brazil, Guiana, Venezuela, and Guatemala; S. leptura, from Surinam; S. villosa, from Brazil; S. Kappleri, and S. leucoptera, from Surinam; S. brevirostris, from Brazil; and S. plicata, from Costa Rica. Rhynchonycteris naso, the Sharp-nosed Bat, is allied to these, but distinguished especially by its very pointed snout. It inhabits Brazil, Surinam, and Guiana.
[218] Emballonura monticola.
[219] Other known species are Emballonura nigrescens, from Amboyna, Ternate, and Australia; and E. semicaudata, an inhabitant of the Samoa, Fiji, and Pelew Islands. An allied African species is Colëura afra, which, however, presents some characters indicating a relationship to the American Saccopteryx.
[220] Taphozous perforatus.
[221] Other described species of the genus are:—Taphozous longimanus, with a large throat-sac in the male, found in India, Ceylon, and Burmah; T. melanopagon, with no throat-pouch, but usually with a small black beard under the chin (see [figure above]), an inhabitant of India, Penang, Burmah, Cochin China, Java, and the Philippine Islands; T. Theobaldi, from Tenasserim; T. australis, from Australia and New Guinea; T. mauritianus, with white wings, from tropical Africa, Madagascar, and the Mascarene Islands; T. saccolaimus, from India and the larger Eastern islands; T. affinis, from Labuan; and T. Peli, from tropical Africa. The Valve-tailed Bat (Diclidurus albus), a native of Brazil, is remarkable for its whitish colour, and especially for the presence of a curious horny case, composed of two parts, which covers the extremity of the tail, and is attached to the upper surface of the interfemoral membrane.
