broad, notched in front, rounded behind, and extended on either side towards the front part; there 

 is a small, short siphon and a not very prominent muzzle ; the tentacles are subulate, very thick at their

30. TRIPHORIS, Besliayes. 



1. Teiphoeis speciosus. PL XI. Kg. 28 a, b. Triph. testa, acute turrita, medio subcylindracea, 

 anfractibus octodecim ad viginti, biseriatim nodatis, nodorum serie superiore proininula, anfractu ultimo 

 tubulato, valde producto, canali etiani tubulato ; albida, linea spirali aurantio-rufa undique tincta. 



Hab. China Sea. 



The last whorl is curiously produced beyond the diameter of the shell in the form of a 

 tube ; and the canal is also tubular. The whorls are characterized by two rows of nodules, 

 of which the upper is much the more prominent, and has a fine, spiral, orange-red line 

 beneath it. 



2. Teiphoeis sutuealis. PI. XL Pig. 29 a, b. Triph. testa turrita, anfractibus duodecim ad tre- 

 decim, eximie triseriatim granuloso-carinulatis, suturis concavo-impressis, leevigatis ; pellucido-alba. 



Hab. China Sea. 



The aperture of this delicately grain-keeled species, which is characterized by its hollow 

 sutures, is incomplete. 



■3. Teiphoeis alveolatus. PI. XL Pig. 30 a, b. Triph. testa elongato-pyramidali, anfractibus viginti 

 ad quatuor et viginti, planulatis, spiraliter triseriatim liratis, hrarum interstitiis clathratis ; intus extusque 

 fusca. 



Hab. China Sea. 



The whorls of this species are flattened and deeply latticed throughout. The aperture 

 is incomplete. 



4. Teiphoeis dexteoveesus. PI. XL Pig. 31a, b. Triph. testa elongato-pyramidali, gracili, an- 

 fractibus sedecim ad octodecim, medio concavis, spiraliter tricarinatis, carina mediana multo minore, 

 carinarum interstitiis sub lente minute concentrice striatis, sordide alba. 



Hab. China Sea. 



This species differs from the rest of the Triphorides under consideration in being con- 

 voluted to the right. The surface of the whorls is concave, and keeled at the upper and 

 lower margins. A fine keel intervenes in the centre, and the interstices are sculptured 

 concentrically with very minute stria?. 



5. Teiphoeis veeetjcosds. PL XL Pig. 32 a, b. Triph. testa gracillimo-subulata, anfractibus 

 octodecim ad viginti, granoso-clathratis, granis transverse oblongis ; sordide alba.
