(PL VI, fig. 4) of another small example, also given to me by 

 Dr. John Young, as it is slightly flatter than that of the shell 

 originally figured. Besides the specimens formerly mentioned, 

 Mr. J. Smith has four from the Lower Limestone Series of Dykes, 

 Kilbii'nie, and one from the Upper Limestone Series of High 

 Smithston, Kilwinning. In the Liege Museum I observed a shell 

 from Vise resembling this in shape and ornamentation, but much 

 larger : the four lower whorls, which alone are preserved, have a 

 length of 5 '5 millimetres and greatest width of 2-25 mm.

Kemarks. — As this species appears to be rare, it is interesting 

 to record that Mr. J. Smith has three additional well preserved 

 specimens, one from Moss Mullock, in the Upper Limestone Series, 

 one from Craigenglen, and the third from Law, Dairy, in the 

 Lower Limestone Series. He has also two worn shells, which 

 probably belong to this species, from the last-named locality. The 

 example from Moss Mullock has the protoconch intact : it stands 

 up detaelied from the post-embrj^onic whorl, and is nearly orbicular 

 in form.

Holotype. — Op. cit. pi. iv, fig. 7. Geological Survey Collection, 

 Royal Scottish Museum, Edinburgh. 



Locality and horizon. — Woodhall, near Edinburgh, in the 

 Calciferous Sandstone Series. Four specimens in the Kirk by 

 Collection, Hancock Museum, Newcastle-upon-Tyne, appear to 

 agree with this species. The}^ are from Randerstone Castle, also in 

 the Calciferous Sandstone Series.

Remarks. — Since this is one of the rarer s^^ecies, it is worth 

 noting the existence (in Mr. J. Smith's collection) of a specimen 

 from the same localit}^ as the holotj^pe, and also of others from 

 High Smithston and Moss Mullock, Kilwinning, in the Upper 

 Limestone Series.
