in other allied species. Id. 1. c. pp. 256-263, pis. v.-vii.

Nassa. F. P. Marrat discusses the specific characters, and comes to 
the conclusion that there are numerous intermediate forms between 
species hitherto admitted as distinct by most authors ; many special 
instances are mentioned by him ; P. Liverp. Soc. 1879. He also compares 
many recent and fossil species, with the conclusion that many of the latter 
are only sculptural varieties of the former ; P. Liverp. Geol. Soc. 1879. 
[The author may be right in many instances, but the Recorder fears that 
he goes too far in his views ; for instance, he has never found among 
large numbers of Mediterranean shells specimens intermediate between 
N. reticulata and cuvie.ri.'\
