The typical N. layeniformis is usually 110-180 p in 
length, although in New Zealand it reaches a length 
of 160 p (Penard); small forms 85-100 mw are not 
uncommon in some localities and are easily recognized, 
but the smallest individuals closely approach N. tubu- 
lata Brown in size and general proportions but always 
possess the characteristic torulose neck. On the other 
hand individuals of N. tubulata are found in which 
the neck is slightly but distinctly torulose, and when 
these measure about 75 w in length it is often difficult 
to decide to which species they belong.
