however, may be inferred from the feeble groove running round 

 the anterior portion of the body-whorl. The columella is exca- 

 vated, and for the size of the shell its plicated anterior extremity 

 is not very large. Professor Tate remarks that this species is 

 intermediate in character between A. hehera and Apseudaustralis.

This may be readily distinguished from all other Australian 

 Tertiary Ancillte by the peculiar aspect of the callous growth 

 around the spire, which is sculptured with narrow, sharply 

 rounded, spiral ridges of unequal size, the larger with two or 

 three smaller ones interposed. The spiral band, though deep, 

 is very narrow, and terminates with a sulcated denticle. The shell 

 is almost cylindrical.

This small shell resembles A. semihcvis, but it has a more 

 obtuse apex, and is strongly angulate at the suture ; callus com- 

 paratively thin, denticle not prominent.
