somewhat blackish tinge prevails), the very numerous flexuous ribs 

 and fine spiral lirse are the chief characteristics. The last mentioned 

 do not cross the longitudinal ribs ; and around the top of the 

 whorls the first liration below the suture is somewhat remote from 

 it ; and also two which encircle the body- whorl near its middle are 

 rather further apart than the others, thus leaving the series 

 of little pits between them somewhat lai'ger than those between 

 the other lirae. Nassa Wilsoni, C. B. Adams, from Panama, is the 

 only species which bears any relationship to the present ; but 

 there are many distinctive difierences between them.

Eeeve describes the colour of this species as " light brown, encir- 

 cled with a pale band ;" and his figure is tinted a dirty olive, with a 

 bluish band beneath the suture. Neither of these colourings is 

 quite accurate. The type is of a pale purplish horn-colour, the 

 upper whorls with a single pale band round the middle, and the 

 body-whorl with three such zones ; the labrum is somewhat thick- 

 ened, and armed with about seven denticles ; the columella is 

 stained with brown, with a small tubercle above, and on that of 

 the Solomon-Island specimen there are one or two at its base.

There is another remarkable instance of wide geographical dis- 

 tribution, supposing both the above localities to be correct. Of 

 the identity of this specimen from the Solomon Islands with ex- 

 amples from Central America there is not the shadow of a doubt. 

 It has been compared with typical examples of mcesia received 

 from Sir Edward Belcher and labelled in Hinds's handwriting, and 

 in no respect differs from them. The number of the whorls should
