Lieut. -Col. Sykes in the Chair. 



Drawings were exhibited of four Fishes of the River Quorra, made 

 by Lieut. Allen, Corr. Memb. Z. S., from specimens obtained by 

 him during his late voyage up that river into the interior of Africa. 

 They exhibit the forms of Lutes, Cuv. ; Mormyrus, Ej. ; Sudis, La 

 C<^p; and Notopterus, Ej. ; and thus tend, in common with the spe- 

 cimens from the same expedition exhibited at the Meeting of the 

 Society on June 10 (page 45), to illustrate the analogy borne by the 

 Fishes of the rivers of Western Africa to those of the Nile. 



A specimen was placed on the table of a Toucan, apparently 

 hitherto undescribed, and forming part of the collection of N. C. 

 Strickland, Esq., by whom it was communicated for exhibition. 



Mr. Gould, at the request of the Chairman, pointed out its distin- 

 guishing characteristics. By its comparatively short bill, which is 

 furrowed on the sides, and broad and flattened on the cuhnen, with 

 the base of the under mandible extending obliquely beyond the line 

 of the eye ; by the shortness and roundness of its wings, of which the 

 fourth quill-feather is the longest, the fifth, sixth, and seventh being 

 nearly of the same length; and by the comparative shortness of the tail, 

 which is less decidedly graduated than in the typical P^erof/Zo.^fs? ; this 

 bird agrees with the species described in Mr. Gould's ' Monograph 

 of the Ramphastidte,' as the Pter. prasrnus, Licht., and Pter. sulcatus. 

 Swains. With those species Mr. Gould proposes to associate it in 

 a group, to be designated, on account of the grooved bills of the Birds 

 comprised in it, Aulacorhynchus . From the other two species it is 

 readily distinguishable by the white band nearly surrounding the 

 base of its bill, and by the blood-red spot on the rump. The Jatter 

 character affords the trivial name of the species, which may, for the 

 present, be inserted in the account of the Toucans given by Mr. 

 Gould at the Meeting of July 8, 1834, (page 78,) immediately before 

 the Pter.prasinus, Licht. 



Pter. h^ematopygus. Pter. svpra subolivaceus, infra ccerulescenti- 

 viridis, pectore saturatiore ; uropygio coccineo ; rectricibus qua- 

 tuor infermediis brunneo apiculatis. 

 Long. tot. 14 poll. ; rostri, 2-| ; alee, 44 ; cauda, 5\ ; tarsi, l-J-. 

 Desce. Rostrum saturate castaneum albo ad basin subcinctum, 

 Orbitse rubrae. Pedes olivaceo-brunnei. Sexus uterque, sicut in 

 Pter. prasino et Pter. sulcato, similis. 



The precise part of South America in which this bird was cap- 

 tured has not been ascertained.
