*' In the obsolete channel, occasionally visible at the top of 

 the aperture, this shell has possibly some relation to Gould's 

 M. sectilabre. The indentation, invariably present \u the internal 

 callus of the aperture, seems to have some reference to the 

 obliterated channel, and shows a passage to the Pupince. The 

 form has a great resemblance to that of the gigantic P. grandis, 

 Forbes [forhesi, Pfr.), which it exceeds in size. As in that shell, 

 the great length of the penultimate whorl, aboA'e the aperture, 

 contrasts with the shortness of the same part in the allied species 

 M. chnjsallis, Pfr," (Benson.) 



The accompanying figui'es have been drawn from a specimen in 

 the British Museum, measuring 34 mm. in length, 18 mm. in 

 diameter.
