46 ZOOLOGY OF THE VOYAGE OE H.M.S. SAMAEA.NG. 



Hab. China Sea. 

 A slender species, latticed throughout with transversely oblong granules. 



6. Teiphoeis granulatus. PI. XI. Fig. 33 a, b. Triph. testa turrita, medio subcylindracea, anfrac- 

 tibus duodecira ad quatuordecim, triseriatini granulatis, granulis regularibus confertis, anfractuum suturis 

 subinipressis ; sordide alba. 



Hab. China Sea. 



Distinguished by its short, cylindrical form, and by the precise arrangement of the 

 granules with which it is sculptured. 



7. Triphoeis gemmulatus. PI. XI. Pig. 34 a, b. Triph. testa pyramidali, basi concavo-planuJata, 

 anfractibus duodechn ad quindecini, planulatis, triseriatim granulatis, seriebus distantibus, mediana fere 

 obsoleta, inferiore prominula ; pellucido-alba. 



Hab. China Sea. 



A very distinct species, of true pyramidal form, encircled with three distant necklaces 

 of granules, of which the middle is almost obsolete. 



8. Teiphoeis pyramidalis. PL XI. Pig. 36 a, b. Triph. testa pyramidali, basi subplanata, anfrac- 

 tibus ad octodecim, superae et interne bicarinatis, earinis granulatis, inferiore minore ; rufo-fuscescente. 



Hab. China Sea. 



"Each whorl of this species is encircled with two granuled keels round the upper part 

 and two round the lower part, and in each instance the lower keel is the smaller. The aper- 

 ture, as in the preceding species, is incomplete. 



9. Teiphoeis nodifertjs. PI. XI. Pig. 37 a, b. Triph. testa turrita, anfractibus duodecim ad qua- 

 tuordecim, medio subangulatis, triseriatim nodosis, nodis transversim oblongis, ad angulum majoribus, 

 apertura rotunda, superne sinuata, canak' tubulato ; alba. 



Hab. China Sea. 



This, and the first here described, are the only species of which the specimens are 

 complete at the aperture, and have the tubular canal which is characteristic of the genus. 



6. PARASITICA. 



31. STYLIFER, Broderip. 



The accounts hitherto given of this parasitic mollusk, not being derived from living- 

 specimens, have not been satisfactory. Mr. Broderip described the mantle (Pro. Zool. Soc. 

 1832, p. 61) as thick, very large, and cup-shaped, enveloping the last whorl of the shell, 

 whilst the animal presented only the rudiment of a foot. Mr. Gray observes (Zoology of
