tured to name this shell in memory of the Rev. David lire, the author of 
the “ History of Rutherglen and East Kilbride,” a work which contains the 
best enumeration of the fossils of the independent coal formation which has 
yet been published in this country.

Length from one to two inches ; whorls five or six, the upper part set 
round with two series of tubercles ; outer lip slightly toothed ; pillar lip rug- 
ged and granular. In, a young specimen which I received from the late Rev. 
James Lambert, Cambridge, as from Plymouth Sound, the whorls have nu- 
merous, fine, waved, spiral striae. These are crossed by more numerous and 
ime longitudinal striae, together with obsolete wrinkles of growth, which on 
the top of the spires, constitute well defined subtubercular rido-es. The 
white cover of the tube at the base of the pillar is finely granular. °
