Q7. Stone on Birds from Colombia. 



[On a Collection of Birds from the Vicinity of Bogota, with a Review 

 of the Suiith-Anierican Species of Speotyto and Troglodytes. By Witmer 

 Stone. Proc. Ac. Nat. Sci. Philad. 1899, p. 302.] 



The Academy of Natural Sciences has come into pos- 

 session of a valuable collection of birds, made near Bogota 

 and on the surrounding ranges by the late Dr. J. W. Det- 

 willer, with localities attached to the specimens. Mr. Stone 

 now catalogues them, and reviews the S. American species 

 of Speotyto and Troglodytes. Of the former genus he 

 separates, as a new subspecies, ^. cunicularia tolimcB ; and 

 of the latter he describes, as a new species. Troglodytes 

 columhce. 



68. Wittierby on the Birds of South-western Spain. 



[Two Months on the Guadalquiver. By Harry F. Witherby, F.Z.S., 

 M.B.O.U. Reprinted from ' Knowledge,' 1899.] 



This is a pleasantly written description of a visit to ground 

 which is already familiar to readers of this Journal; in fact 

 there is now a sort of dragoman who provides boats, lodging, 

 and all accessories for '' trippers '^ to a district which was 

 once " wild " Spain. This was an agreeable " outing " ; but 

 we are glad to find that Mr. Witherby has more serious 

 ambitions, and that he has started for Khartoum and the 

 country beyond on the White Nile, accompanied by two 

 experienced collectors.

We have received the following letters, addressed " to the 

 Editors of 'The Ibis'^':— 



Sirs, — The January number of ' The Ibis' for the present 

 year contains figures of two birds, recently described by 

 Mr. Weld-Blundell and Lord Lovat in the Bull. B. O. C. 

 vol. X. pp. xix, XX. I think I can easily show that neither 

 of these birds can stand as a new species. 



The first bird figured is Oriolus meneliki W.-B, & L.,
