was convinced that it was a new species. Having compared the shell 

 with the species in the Enghsh collections and the descriptions in 

 Pfeiffer, and being satisfied that M. Denicke was correct in his idea, 

 I propose that it should be named after that conchologist. 



BuLiMus Denickei. 



Shell conical, trochiform, white, the upper whorls small, forming 

 a rather produced tip, the others rapidly enlarging, slightly convex, 

 forming a conical spire, the last angularly keeled ; axis perforated ; 

 mouth rhombic ; outer Up slightly reflexed, acute ; throat deep rose- 

 coloured. 



Hab. Chala, near Callao, on the Whitesand Hills. 



To the preceding communication by Mr. Gray, the following de- 

 tails were added by Mr. Lovell Reeve : — 



BuLiMTJS Denickei. Bui. testd pyramidali-conicd, subampliter 

 umhilicatd, apice papillari, anfractibus supern^ convexo-decli- 

 vibus, medio acutangulis, carinatis, undique peculiariter cor- 

 rugatis et malleatis, opaco-albis, immaculatis, aperturd sub- 

 oblongo-ovatd, labro tenui, simplici, effuse, aperturce fauce in- 

 tense purpureo-rosed. 

 Hab. Found imbedded in sand at the top of a lofty hill near the 

 Port of Chala, Peru, by M. Erneste Denicke. 



This interesting species of Bulimus is of about the same size and 

 form, and belongs to the same type, as B. lemniscatus, inhabiting 

 Ilo, Peru. Specifically it is very cUstiuct, the entire surface of the 

 shell being peculiarly indented and shrivelled, and of an opake un- 

 spotted white. The interior of the aperture is of a deep purple-rose 

 coloui". 



On a new species of Musophaga. 

 By John Gould, F.R.S. 



Mr. Gould exhibited to the meeting a drawing by Lieut. J. R. Stack, 

 of a new and beautiful species of Musophaga, of which a living ex- 

 ample had been for the last ten years in the possession of Lady Ross, 

 at St. Helena. Mr. Gould also exhibited some feathers shed from 

 the wings and tail of the bird, an examination of which, and of the 

 drawing, satisfied him that the bird was quite distinct from all pre- 

 viously described members of the genus. 



Lady Ross, who is at present in England, had informed Mr. Gould 

 that the bird was about the size of a heivpheasant, and that it had 

 been brought to St. Helena from the western coast of Africa, but the 

 precise locality in which it had been procured was unknovra to her. 



For this interesting addition to the Musophagce Mr. Gould proposed 

 the specific appellation of Rossce, in honour of its amiable owner. 



Musophaga Ross^. 



Body, wings and tail rich deep blue ; primaries and secondaries 

 arterial blood-red, narrowly margined and more broadly tipped with 

 purplish brown, as in the other species of the genus ; crown sur- 

 mounted with a high rounded crest of hair-like blood-red feathers ; 

 bill and denuded orbits yellow ; irides brown.
