The author rightly compares this shell, of which I have five 

 examples from the collection of the late Sir R. W. Ravvson, K.C.M.G., 

 with a species I myself discovered in March, 1872, on the Florida 

 Keys, where it occurred at Key West at low tide rarely and locally, 

 amongst blocks of coral, often tenanted by Paguri, indeed it was 

 difficult to get good specimens. This shell, named by me in MS. 

 and afterwards (1878) described^ by Mr. G. B. Sowerby as Z. 

 cayohiiesonicus^ is undoubtedly near funebris, but I think absolutely 

 distinct. As Mr. Preston well points out, the whorls are more ventri- 

 cose, sutures impressed, surface cancellate.

An elegant, brightly coloured species, nearly allied toZ. nielanorhyn- 

 chus, Tapp.-Can., but differing in its much more attenuate contour, 

 and enhanced sutural impression, the whorls on that account shewing 

 greater ventricosity. The ribs are more numerous too, eight on the 

 body whorl of nielanorhynchus, which is almost black tipped at the 

 base, while in Z. liesterce the coloration is a w^arm chestnut brown. 

 It gives me much satisfaction to pay a small tribute to a near relation 

 in thus adopting her Christian name for this species, my aunt, Mrs. 

 Fenwick, wife of the late Col. Thomas Fenwick, R.E., resident 

 several years in Mauritius, from whence she obtained for me the first 

 collection of shells 1 ever possessed.
