is slightly more slender in shape, the whorls are rather flatter, the strise are more 

 oblique, and the edges of the whorls overlap the suture to a greater degree. 

 Nevertheless the general aspect of the shell is very similar, and the enlarged 

 pattern which Phillips gives exactly corresponds and shows the beading. Upon the 

 whole, Mr. Lee's specimen is quite as much like Phillips's figure as are many of his 

 other types to the figures which he gives of them ; and as many of his originals 

 from Barton were in Mr. Lee's Collection, I am strongly of opinion that the present 

 fossil was the actual shell from which Phillips drew his figure and described this 

 species. It is to be noted that there is every appearance of imperfection about 

 the base of his figure, which is just the place where the present fossil is defective. 



We may therefore, I think, take it for granted that the present species, as 

 represented by the shell in the British Museum, is the Loxonema lincta of Phillips ; 

 and we have next to observe that Phillips, although placing it under the genus 

 Loxonema, suggests that Buccinum imbricatum, Sow., and B. arculatum, Goldfuss, 

 should be referred to the same genus as this shell : these latter he ultimately 

 included in his new genus Macrocheilus, and it is evident that Mr. Lee's shell 

 belongs to that genus. This gives another argument for its identity with Phillips's 

 shell, as he speaks of " the disproportion of the whorls (owing to the last including 

 and concealing so much of the penultimate) ; " and this feature, not seen in his 

 figure, would remove one of the differences we have noted above. 



Affinities. — From M. subcostata, Schloth., sp., the present shell is separated by 

 its much larger spire and shorter body-whorl, and by the simpler character of its 

 ornamentation. From the other accompanying species it is distinguished by not 

 being smooth, and from most of them by the shortness of its body-whorl.
