addition to those from the Cape region, the Museum also possesses 

 specimens from Angola and the Congo, but it is possible that these 

 had been imported with horses or mules. The localities, etc., of 

 the specimens in the Museum Collection are as follows. Cape 

 Colony : Colesberg, 1860, and Cape Town, 1864 (R. Trimen) ; 

 Burghersdorp, 1865 (Dr. Kannemeyer) ; King Williamstown 

 District, 1899 (Miss Barrett) ; Deelfontein, 1902 (presented by 

 Colonel A. T. Sloggett, C.M.G., R.A.M.C.) ; Griqualand West, 

 1902, " from horse " (O. E. H. Barrett-Hamilton) ; Bechuanaland, 



1907 (F. W. Jones). Natal : Durban, 1853 (purchased from 

 Stevens) ; Estcourt, January, 1897 (G. A. K. Marshall], 

 Basutoland : Maseru, January 13th and May 25th, 1902 (Captain 

 Richard Crawshay), and 1907 (L. Wroughtori). Orange River Colony : 

 Bloemfontein, 1898 ( Wilmari). Transvaal : Pretoria, 1904 (Dr. 

 A. Theiler, C.M.G.). Southern Rhodesia : Selukwe, February, 



1908 (E. C. Chubb) ; exact locality uncertain, 1908, "brought up 

 to Rhodesia on horses from the Orange River Colony " (LI. E. W. 

 Bevan). Angola : Bembe Mines, Lat. 7 22' S., 1860 (J. J. Monteiro). 

 " Congo," 1843 (Surgeon Andrew Curror, R.N., H.M.8. Waterwitch). 



According to von Olfers,f the type of Hippobosca rufipes was 

 taken by Lichtenstein on an ostrich (Struthio australis, Gurney) 

 at the Cape of Good Hope, but the describer of the species very 

 reasonably suggests that the fly may have come from a quagga 

 (Equus quagga, Boddaert), since in the early decades of last century 

 quaggas, which were then present in enormous numbers on the 

 Karroo, were very frequently found mingling with the flocks of 

 ostriches. As additional evidence that H. rufipes sometimes strays 



animatis corporibus in corpore animate reperiundis, Pars I." Hagen also gives the 

 place and date of publication as " Goettingse, 1815." In none of the catalogues 

 that I have been able to consult, however, is there any mention of an 1815 

 (Gottingen) edition; the 1816 (Berlin) edition alone is mentioned, and the title 

 quoted is the same as that given above, which is taken from the Museum copy, 

 formerly in the library of Sir Joseph Banks. Wiedemann (" Aussereuropaische 

 zweifliigelige Insekten," II., p. 604, note, 1830) quotes the 1816 edition. Since the 

 foregoing was written, I have received a most courteous letter from Dr. F. Beicke, 

 of the Konigliche Universitats-Bibliothek, Gottingen, informing me, in reply to an 

 enquiry, that a copy of the 1816 edition of Von Olfers's work is the only one 

 contained in that institution ; and that, in spite of an exhaustive search, he has 

 been unable to discover any evidence of the existence of an 1815 (Gottingen) 

 edition.
