 whorl rather suddenly increasing, and sharply 

 angled at the periphery. Colour pale straw, 

 base and a subsutural band white. Apex ap- 

 parently heterostrophe, following whorl swollen, 

 next narrower ; as the whorls progress they 

 become slightly flatter. Whorls nine, parted 

 by a deeply channelled suture. Aperture with 

 a single slight fold. Length, 6 mm. ; breadth, 

 1 -5 mm. 



A single specimen with a broken lip from 

 63-75 fathoms off Port Kembla.

M YX A, gen. nov. 



A genus of the Pyramellidio, umbilicate, witli few whorls, no 

 columella fold, and the lip produced anteriorly. 



Type M. exesa. 



This genus might be taken for Niso, if it were not for the 

 heterostrophe apex ; so that it bears the same relation to Niso 

 as Enlimella does to Eulima.
