of smaller size, and attributes the larger size of the female to the neces-

Nassa. The variability of the shells in this genus is discussed by F. P. 
Marrat in a separate pamphlet, “ Varieties of Shells of Nassa, Liver- 
pool : 1880, with 3 pis. 95 pp. After a general introduction to the subject, 
he describes the animal of the genus, and gives a list of references to the 
animals of various species in different works [The author is mistaken 
in quoting Olivi’s Zoologia Adriatica, where no description of the 
living animal is given, and he omits to name the very first figure and 
description of a living animal of the genus given by Fabius Columna, 
De Purpura, Rome, 1616, cap. 4, regarding N. mutabilis']. He also notes 
38 species in which the operculum is serrated, 16 in which it is cre- 
nated, and 12 in which it is plain. He then gives a list of 1321 
numbers species or varieties (the latter diagnosed in a few words), 
describes 21 new species (see infra), and gives some examples of natural 
series of intimately connected species, passing one into another 
according to him ; he describes, finally, several species and varieties of 
Nassa, dredged on the same spot off Malta by Captain Horsfall, men- 
tions some deformities, and hints at the probability that this genus may 
be constituted “ by one shell in an endless varieties of forms.” [Cf. also 
Zool. Rec. xvi. Moll. p. 42.] Some earlier papers on the same subject by 
the author are appended to this publication.
