Test similar to that of the type but smaller ; plasma 

 and pseudopodia as in the type.

Australia (Fenanfy. Seychelles (Wailex). 



The typical N. lageniformis is usually 110-130 JJL in 

 length, although in New Zealand it reaches a length 

 of 160 p (Penard) ; small forms 85-100 //, 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 /A in length it is often difficult 

 to decide to which species they belong.
