We have in vain tried to matcli this small species. It is 

 undoubtedly an Alectryon, its congeners \iQin^N.monile^ Kien., 

 and allies, although, from the description, N. (Niotha) multi- 

 costata, A. Ad., a species included in the section remarkable for 

 the deep transverse sulcations, but which are obsolete in it, 

 comes very near AT. fretorum. Our species would seem to differ 

 in the conspicuous spiral sulcation just below the sutures, in the 

 broader contour in proportion to the length, and one or two 

 minor details. We are especially indebted to Mr. Ernest R. 

 Sykes for carefully comparing this Nassa with the incomparable 

 series in the National Collection, South Kensington.

 Conch, vol. viii. p. 273, pi. ix. fig. 2, 1896.) 



One of the few molluscs, lately described by us from Lifu, 

 that has occurred in this collection. Its nearest ally is 

 N. plebecula, Gld.

A series embracing the type with zigzag lines on a black 

 ground, merging into the condition in which the white streaks 

 are broken up into rounded or triangular white spots, and 

 evidently occurring together.
