Hutton's type, w ich was stated to be from Waihao (2.e., the greensands), 
has been lost и. 1915, p. 10). Since several similar s species occur at 
this vend Meere localities (all dig d classed A. suturalis), it is therefore 
importa to choose a suitable neotype. Obviously, if there were no 
аре he specimen used nd Suter for his description should be taken, 
but Sa RE the кле барг; ubtful. The tablet is labelled “ Waihao,” 
but the form and preserva a of the shell , and the matrix within it, were 
noticed by Mr. 
found in the 
greensand Ta re. Similar shells and matrix occur above the limestone of 
the Pareora River, at Blue Cliffs and Mount Horrible, so it seems likely 
that the specimen was from one of these localities and had become mixed 
ith a Waihao collection. Perhaps it is really from the Waihao vag fe but 
from a horizon above the limestone. Hutton distinctly says his 
shells were from the greensand, so unless his actual type can be ath uced 
the neotype should be chosen from that bed. His figure is of a globose 
shell with a low spire, and of large dimensions, and does not look very like 
a Waihao shell. Indeed, it is more like Suter’s specimen, so the error of 
locality may have crept in before Hutton handled the specimen, and Suter 
may have actually used the type for his description without kno owing it. 
Since there are no means of finding out which is the correct solution,
