prove that Geoffrey's work was not actuall}^ published until 1818, 

 but this evidence can hardly be accepted as conclusive. When spe- 

 cific names of long standing, based on type-specimens from known 

 localities, as well as several generic names, are affected by the change 

 of reference, it seems best to require absolute proof to discredit the 

 date of publication of a work like the "Description de I'figypte." 

 If such proof is ever discovered, RMnopoma and other generic and 

 specific names will date from Oken, 1816, as cited above.

Genus COLEURA Peters. 



1867. Coleura Pkters, Mon.-ber. K. Preuss. Akad. Wiss. Berlin, p. 479. (C. 

 afra.) 



Only one of the two known continental species of this genus of 

 bats is included in our East African collections. The unrepresented 

 species, C. gallarum Thomas, is of doubtfid validity, probably at the 

 most only a northern race of Coleura afra. The old record of a 

 Seychelle Island species at Zanzibar has been questioned bj^ Thomas.^ 



COLEURA AFRA (Peters). 



1852. Evihallonura afra Peters, Reise Mossambique, Sang., p. 51. (Mozam- 

 bique; type in Berlin Museum.)

British East Africa: Voi (HeUer). 



Some measurements from this specimen arc: Head and bod}^, 65; 

 tail, 17; foot, 11; ear, 17; forearm, 48. Skull: Condylobasal length, 

 without premaxillary bones, 15.8; greatest length, 17.4; zygomatic

 a.cns= T. perforatus.) 



Bats of this genus seem to be rare or difficult to obtain in East 

 Africa, as only a single specimen was collected on each of the larger 

 expeditions.
