The great variation in length of specimens included under this 
species is one of the most notable facts. There can, however, 
be no doubt as to the identification of all the material as this 
species. The unicostate scales give a simple and very easily 
applicable test by which it can be separated from the following 
species or any other of this group. It seems to grow under a 
wide range of conditions, this presumably accounting for the 
variation in size, the small specimens being probably only physio- 
logical forms. In the West Indies it rarely reaches as full develop- 
ment as in South America, but even the smallest specimens 
measured were usually fertile.
