Third lower molar smaller than first or second, but with all the elements complete. Skull (fig. 12) very delicate and lightly built, the rostrum about half as long as brain case, broad and flat, with distinct though not excessive lateral inflation and a broad median longitudinal groove. Anterior lower border of orbit so expanded that toothrows are not visible from above. Postorbital processes very slender, extending nearly to zy- gomata. Basisphenoid pits broad and shallow, the median divi- sion barely indicated by a low ridge. Audital bulla smaller than combined area of pits, distinctly emarginate antero-internally. Mandible with angular process bent conspicuously outward. Tibia scarcely flattened posteriorly. Extern- ally characterized by the slender form and absence of both specially elongated muzzle and deep depression between eyes. Like all of the Old. World mem- bers of the family, Emballonura lacks unusual glandular development in the wings. Species examined.—Emballonurasemi- caudata (Peale), E. peninsularis Miller, E. anambensis Miller, and E. nigre- scens (Gray). Remarks.—In the presence of 2 - 2 up- per incisors, in the slight flattening of the tibia and in the special modifica- tions that distinguish most of the other genera, Emballonura is the most primi- tive member of the family. It is also the most widely distributed genus in the gr'oup, in this respect approached by Taphozous only. Genus COLEURA Peters. 1867. Coleura Peters, Monatsber. k. preuss. Akad. Wissensch., Berlin, p. 479. 1878. Coleura Doeson, Catal. Chiropt Brit. Mus., p. 364. Type-species.—Emballonura afra Peters. Geographic distribution.—Eastern Africa from Mozambique to upper Egypt; Seychelle Islands. Number of forms.—Only two members of this genus have been de- scribed. Characters.—Like Emballonura, but upper incisors only 1 -1; pre- maxillary strongly bent i
