cally parallel, there being no rapid increase in the diameter of the successive .chambers. 

 The typical form, in which the chambers are few in number and increase rapidly in 

 diameter towards the oral extremity, occurs at WS 71 and 93, but is much more finely 

 costate than is usually the case. There is the usual variation, especially at WS 83, where 

 the species is common, and included a marginuline specimen which might be attributed 

 to Amphicoryne falx, Jones and Parker, but is doubtless merely a local sport of a common 

 species. At the same station a complete series might be obtained linking up N. simplex 

 and A'^. scalaris.
