et tenuissime striatis ; canali basali brevi, recurvo ; apertura 
fere circulari; rubida, serie inferiore granorum cerea. 
Long. 8, diam. 23 mill.

The striking contrast between the circle of waxen-coloured beads 
on a dark red renders the above species conspicuous and easily re- 
cognizable. 
6. TRIPHORIS PERFECTUS. 
T. turrita, tenuiuscula, nitida ; anfractibus decem, cingulis dua- 
bus granorum ornatis, serie inferiore majore, moniliformi ; su- 
tura sulcata; canali basali oblique recurvo; canali posteriore 
tubulato, elongato, clauso, repando; apertura circulari; alba, 
serie superiore granorum rufescenti-fusca. 
Long. 4, diam. 13 mill. 
Hab. Ins. Kauai. 
I have attached the above name to this species, as it represents 
the genus fully developed. 
T. mirabilis (C. B. Ad.) and T. mirificus (Desh.) are of the same 
type. 
7. TRIPHORIS PUNCTATUS. 
T. elongato-turrita, solida; anfractibus quatuordecim, tricari- 
natis, carina mediana multo minore, interstitiis valde punctatis ; 
sutura sulcata, levi; apertura subcirculari; alba, pallide 
Susco et rosaceo irregulariter maculata. 
Long. 9, diam. 2? mill. 
Hab. Ins. Annaa. 
The above may be recognized by the deep punctures between the 
spiral keels, and smooth sutures. 
8. TRIPHORIS COSTATUS. 
T. subulata, solida, transversim costata, costis equalibus, regula- 
ribus, contiguis, subgranosis, planulatis ; sutura incerta; canali 
brevi, recurvo; apertura subcirculari; basi albida, spira cinereo- 
Susea. 
Long. 8, diam. 24 mill. 
Hab. Ins. Annaa. 
This species is made up of a series of equal-sized ribs, closely con- 
tiguous, rather plane, and somewhat granose; I have not been able 
to determine where the suture runs. 
9. TRIPHORIS ROBUSTUS. 
T. abbreviato-subulata, solida; anfractibus decem, biseriatim 
equaliter granosis, longitudinaliter tenui-striatis ; interstitiis 
suturaque linea subgranulosa spiraliter cingulatis ; canali basali 
brevi, recurvo ; apertura subcirculari; seriebus granorum al- 
bido, fusco et flavo maculatis ; sutura lata, rosacea. 
Long. 6, diam. 2} mill.
