3. Description of a new species of Bulimtjs from Callao, 



COLLECTED BY ErNESTE DeNICKE. 



Communicated by J. E. Gray, Esa., V.P.Z.S. 



Mr. Erneste Denicke, a sailor on board a Hamburg vessel trading 

 with Chili, called at the British Museum, and informed me that he 

 had a new species oi Bulimus, which he had discovered on the White- 

 sand Hill at Chala, near Callao. He further stated that he had col- 

 lected the Chilian shells, and had studied shells in general, and that he 

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

 with the species in the English 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. 



It was pleasing to see the intimate knowledge which he had 

 acquired of the genera and species of shells, and the interest which 

 he took in the study, when we consider the laborious nature of his 

 occupation, and the very little time that he had at his command. 

 The only holidays he had while his ship was in London were spent 

 at the British Museum, at Mr. Cuming's collection, and in the gar- 

 dens of the Zoological Society. 



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 lip slightly reflexed, acute ; throat deep rose- 

 coloured. 



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