The specimen from Stat. 260 is very small, those from Stat. 277 are still much smaller 

 than those I possess from the Red Sea. The specimens are peculiar by their largely spread 

 callosity and dark colour of back. N. pulla is still a rather doubtful species, considered ' by 

 many authors to be only a variety of the preceding species.

Both specimens are typical and easily distinguishable from the next species, with which 

 Tryon united it, and is followed by other authors. Indeed both forms may be only varieties 

 of one and the same species.
