Dec. 9, 1834. — Specimens were exhibited of three species of the 

 genus Bulinus, Lam., which were regarded by Mr. G. B. Sowerby as 

 previously undescribed. He characterizes them as Bul. leucostoma, 

 badius, and bicolor. 



The specimens were brought to England by Mr. Miller, to whom 

 the Society is indebted for their exhibition. 



The reading was concluded of Mr. G. Bennett's paper on the 

 Ornithorhynchus, an abstract of which was given in our Number for 

 April last, Lond. and Edinb. Phil. Mag., vol. vi. p. 307. 



December 23. — 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 Latcs, Cuv. ; Mor- 

 myrus, Ej. ; Sudis, La Cep; and Notopterus, Ej. ; and thus tend, in 

 common with the specimens from the same expedition exhibited at 

 the Meeting of the Society on June 10 (Lond. and Edinb. Phil. Mag. 

 vol. v. p. 311), 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 culmen, 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 Pteroglossi ; this 

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

 of the Ramphastida,' as the Pter. prasinus, 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 latter 

 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, (vol. v. p. 383.) immediately 

 before the Pter. prasinus, Licht., under the name oiPter. hcematopygus. 

 The precise part of South America in which this bird was captured 

 has not been ascertained. 



Col. Sykes, when reading to the Society, in 1832, (see vol. ii., 

 p. 230.) his Catalogue of the Birds of Dukhun, not having exhibited 

 the nest and eggs of the Lonchura Cheet, and of that species of Tailor- 

 bird which he denominated Orthotomus Bennettii, brought them under 

 the notice of the Society on the present occasion. 



The nest of the Lonchura Cheet is a perfect hollow ball, made of 

 a delicate Agrostis, with a lateral hole for the entrance of the birds.
