MELVILL AND STANDEN : SHELLS FROM LIFU. 408 



C.spurca L., but the dorsal confluent markings seem charac- 

 teristic, and the lateral spotting at once separates it from, 

 at all events, typical examples of C. arnica. 



Trivia exigua Gray=T. tremeza Duclos. — Many beautiful 

 and fresh examples of this exquisite species, the most 

 recherchee perhaps of the smaller Trivia. It is recorded 

 from the Sandwich Islands, as well as the New Caledonian 

 group. 



T. globosa Gray. — Two characteristic specimens. Of wide 

 distribution ; we see no difference between the shells 

 from the Eastern, as opposed to those from the Western 

 Hemisphere. It extends from the West Indies, Sandwich 

 Islands, to Australia ; it may almost be deemed cosmo- 

 politan within the tropics. It is not, however, very 

 commonly found in collections. 



T. grando Gask. — Also recorded from Manila. Apparently 

 typical. Several specimens. 



T. pellucidula Gask. — Four examples of what is apparently 

 this species. 



T. vitrea Gask. — Several specimens ; also recorded from the 

 Philippines. 



Family CEKITHIlDAi. 



Triforis carteretensis Hinds. — A plain species with grooved 

 plain spiral keels. The British Museum specimens, with 

 which ours have been compared, are from New Ireland. 



T. cinguliferus Pease. — Several specimens. Also from the 

 Sandwich Islands. 



T. hilaris Hinds. — A variegated species with close receding 

 keels. Several specimens. Also from the Sandwich 

 Islands and the Philippines. 



T. obtusalis Jousseaume. — An obese black noduled shell. 



T. ruber Hinds. — Pale violet, not red, as the name would 

 suggest. Exceedingly abundant. It also occurs at New 

 Ireland, Tahiti, and Isle of Bourbon.
