Cerithium Shoplandi, sp.n. (Pl. IX. fig. 3) ) 
O. testa elongato-fusiformi, solidula; spira supra multum attenuata, 
albo-cinerescente ; anfractibus 10, sex supernis parvis, quatuor 
ultimis longitudinaliter irregulariter costulatis et varicosis, in 
ultimo hic costis omnino evanidis, illic a medio usque ad basin, 
varicibus albescentibus, anfractibus spiraliter duplicato suleorum 
ordine preeditis, interstitiis transversim et interruptim cinereo- 
nodulosis vel lineatis, sex in ultimo anfractu, tribus in penultimo 
ordinibus ; apertura ovata, labro incrassato, intus quinque-suleato, 
suleulis rubro-tinctis; columella obliqua, alba, incrassata, brevi 
rostrata. 
Long. 18, lat. 8 mm. 
An elegant Cerithium, most nearly allied, in my opinion, to 
the larger and coarser C. moniliferum, Dufr., from the Philip- 
pines, the chief distinctive characters besides those of size 
lying in the great attenuation of the upper whorls, the distinct 
ribs, white varices, and the fine red furrowed lines just below 
the inner edge of the outer lip. 
Several examples. It gives me much pleasure to connect 
with this pretty species the name of its discoverer. 
Bittium chrysomallum*, sp.n. (Pl. IX. fiz. £.) 3 
B. testa fusiformi, solida, alba, ochraceo-variegata ; anfractibus 
decem, apicalibus ...?, caeteris apud suturas multum impressis, 
arcte longitudinaliter costatis, costis regulariter, quasi spiraliter 
nodulosis, ultimo, penultimo, et antepenultimo anfractu quatuor, 
ceteris tribus gemmarum ordinibus preeditis, in ultimo infra 
medium evanidis, inde, usque ad basin, pulchre spiraliter lirato ; 
apertura breviter ovata, intus albescente, labro paullum effuso, 
subquadrato, margine columellari obliquo, ad basin brevissime 
rostrato. 
Long. 6, lat. 2 mm. 
A very delicately variegated Bittiwm, not nearly akin to 
any species with which Iam cognizant. It is white, fusiform, 
with regular gemmate ribs, the disposition of these gemma 
giving an appearance of spirals round the whorls, so regularly 
are they disposed ; there are three rows of these in the upper 
whorls, four in the three lowest ; in the body-whorl the ribs 
disappear below the middle, whence to the base are to be 
seen spiral clear-cut lires; the mouth is somewhat compressed, 
outer lip rather effuse, beak very short, columella oblique. 
The variegation of yellow-brown and white is most proncunced 
in the last two whorls. 
* ypvodpaddos, with fleece or sheen of gold; from the pattern.
