and colour of the aperture and tlie plaits on the pillar. The 

 aperture of Vol. concinna is fulvous, and the innev lip, where the 

 mantle has extended, is of the šame colour, with a few traces of ihe 

 longitudinal lineations not yet obliterated. 

 My specimen is the only one I have seen.

Mus. Adamson. 



This species is nearly as solid andponderous as Con. Stercus Mus- 

 carum, Av-hich it resembles somewhat in shape, though Con. Adamsonii 

 is longer in proportion. It has also points which remind the observer 

 of Con. bullatus ; but is more įiearly alliedto Con. discrepans, Conch.

This shell was brought up ou the fluke of the anehor of H. M. S. 

 Mastiff, surveying-vessel, under the command of Lieut. Graves (\vho 

 has already enriched this department of natūrai history by his acti- 

 vity in collecting, 'vrhenever the pressure of his professional duties 

 ■would aUow him to do so,) from amuddy bottom, and a depth of ten 

 iathoms, ofF Napoli di Romania. The shell varies much, and other 

 ■pecimens have not the carinations, &c. nearly so much developed. 



There is a figure of this species in Mr. Sowerby's ' Conchological 

 niustrations,' under the name of Murex cariniferus.

Tliis curious shell, \vhich at first sight reminds the observer of 

 Bulinus Labeo, Brod., (Zool. Journ., vol. iv. p. 222.) brought home 

 by Lieut. Maw, R. N., and presented by him to the Zoological Society 

 of London, from vrhose Museum it has been stolen*, differs .strongly 

 from it, as will be seen by a reference to the figure in the ' Zoolo- 



• This certainly \vas, and I bclieve (\vherever it maybe)i3, the only :»pe- 

 citnen in Euvope. It \vas in reniarkably fine condition.
