Tliis specie.^, of wliich only the shell is known, has an 

 altoiretlu'r different aspect from that of the type of Mesalia, 

 iiaving flatter whorls and numerous oblique costai upon the 

 upper part of the spire. The characters of the aperture, 

 however, show that it is rightly placed in that genus. 



In de.scribing his M. exilis Mr. Sowerby ob.served : — "The 

 actual position of this remarkable shell is uncertain, but I 

 provisionally place it in Mesalia on account of the charac- 

 teristic bas.il sinus." Such being his opinion, it is surprising 

 that he did not refer to Reeve's Monograph of the genu<, 

 published sixty-four years previously, or to other works 

 describin<T Mesalia, issued in the interval. Had he done so, 

 he could not have failed to identify the shell he proposed 

 describing with Reeve's M. melanioides. Having compared 

 the type of that species and the actual shell described as 

 M. eailis, both bt-ing in the British Museum collection, I can 

 testily with certainty to their specific identity. 



The figure in the Ann. & Mag. Nat. Hist, is not good ; 

 it shows the whorls too convex, and the basal sinus to the 

 aperture is badly depicted.
