 Atlas United- States Explor. Exped. (Wilkes), pi. x. f. 1/1 ; Otia, 

 Conchol. p. 62. 



Hab. San Christoval, Solomon Islands {Brazier) ; Wilson's Island 

 {Gould). 



The little shell which I associate with this species, agrees very 

 well with Gould's description, with the exception that the spiral 

 liration which is situated a little above the middle of the whorls, 

 and is larger than the others, is decidedly nodulous ; and that at 

 the suture is also nodulous, the nodules of the latter being smaller 

 than those of the former. The figure given by Gould is not good, 

 as it does not show the little dark-brown spots which exist around 

 the lower portion of the body-whorl. 



77. Vanikoro acuta, Redux, var. — Narica acuta, Recluz, May. de 

 Zoologie, 1845, p. 60, pi. 133. f. 1, 2. 



Hab. San Christoval, Solomon Islands (Br«zier) ; "Lord-Hood Island, 

 Moluccas, and Cape Natal" {Cuming). 



The single example from the Solomon Islands differs somewhat 

 from the types of this species. The umbilicus is narrower, and 

 the spiral sculpture rather coarser, and the strise more deeply 

 incised. 



78. Neritina siderea, Gould, Proc. Boston Soc. Nat. Hist. 1847, 

 vol. ii. ; Otia Conchol. p. 48; Reeve, Conch. Icon. ix. f. 171, a, b. — 

 Neritina dispar, Pease, American Journ. Conchol. vol. iii. p. 285, 

 pi. xxiv. f. 3. 



Hah. San CliristoA-al, Solomon Islands {Brazier); Feejees {Gould). 



The two specimens from San Christoval are very large, measur- 

 ing eleven millims. in length, and are much paler in colour than 

 the typical form. The fine longitudinal wavy lines (not mentioned 

 by Gould) are somewhat distant ; the white triangular spots, which 

 are shaded on the left with purple black, are rather large ; and the 

 last whorl is encircled jiear the middle with two indistinct bands 

 of the same colour. From the series of this species in the 

 Museum collection, it would appear that the smaller the specimen 

 the blacker it is and the white spots fewer.
