upper ones with straight or even faintly concave outlines, pale at the

 lens) ; columella covered with a thin pellucid callus, with three or 

 four oblique plicae at the base ; basal callous band pale luteous, white 

 at the upper edge, with a brown line just beneath, and bordered 

 inferiorly by the uppermost of the basal oblique plicae, which is 

 also brown ; edge of the canal brown.

Hub. Station 14. 



The markings of these little shells, of which there are five, are rather 

 indistinct to the naked eye. The longitudinal pale-brown lines are 

 undulating, or partake of a zigzag disposition. They agree very well 

 with Gould's brief description, and most likely are rightly assigned to 

 his species, of whicli the Museum already possessed a single colour- 

 less example determined by Dr. P. P. Carpenter. 



89. AncilIiAria inornata. (Plate XX. fig. 56.) 



Shell elongate, acuminately ovate, white, faintly tinged with yellow 

 above the sutural line : whorls 4, coated with a thin enamel ; spire 

 moderately acute at the apex, with slightly convex outlines ; last 

 whorl indistinctly transversely striated with two narrow oblique sulci 

 on the lower part, whereof the upper is the deeper and borders the 

 basal balteus ; the extremity of the whorl deeply sulcated, with three 

 or four oblique plicae between the sulcations. Aperture occupying 

 rather more than half the whole length; basal notch broad, shallow. 



Length 8 millims, diam. 3.
