18 Mr. R. B. Hinds's Descriptions of new Shells. 



A fine species with squarish brown spots on a white sur- 

 face ; but I regret that the single specimen in Mr. Metcalfe's 

 collection has neither the apex or mouth entire. 

 7. T. cancellatus. Testa pallide rufente ; anfractibus 15 — 18 bi- 

 carinatis ; carinis albo maculatis ; inter carinas cancellata lineis 

 albis longitudinalibus intervallis fuscis ; sutura sulcata ; apertura 

 subquadrata ; sinu laterali margine contracta. Axis 4^ lin. 

 Geog. Straits of Malacca ; in 20 fathoms. 



JOS"*? 8. T. corrugatus. Testa cornea; anfractibus 17 — 20 bicarinatis, inter 

 carinas corrugatis, medio carina secondaria ; sutura leviter cari- 

 nata ; apertura rotunda ; sinu laterali lineari. Axis 6 J lin. 

 Geog. New Guinea ; dredged from 23 fathoms, among fine gravel. 

 Straits of Malacca; from 18 to 23 fathoms. 



9. T. maxillaris . Testa rosea; anfractibus 16 — 18, superficie laevi- 

 gata, bisulcatis ; marginibus sulcorum granulatis ; sutura sulcata, 

 marginibus granulatis, apertura subquadrata, sinu laterali parvo 

 patulo. Axis 5 \ lin. 



Geog. Straits of Malacca ; dredged from 18 to 23 fathoms. 



This shell is very remarkably characterized. The surface is 

 perfectly smooth, and of an agreeable rose-colour ; but each 

 whorl is divided into three unequal parts by two furrows. 

 The margins of each furrow, and also of the depressed line 

 which marks the course of the suture, are provided with a se- 

 ries of horizontal granulations, which look towards each other 

 and do not appear above the surface of the shell, but under a 

 magnifying glass display an appearance which seems to jus- 

 tify the specific name. 



10. T. micans. Testa gracili attenuata, fusca ; anfractibus 20 — 22, 

 supra coarctatis, triseriatim granulosis, serie inferiore maxima al- 

 bida, superiore minima ; apertura subquadrata ; sinu laterali lineari. 

 Axis 6 lin. 



Geog. New Guinea; dredged from mud in from 5 to 18 fathoms. 



11. T. asperrimus. Testa gracili attenuata ; anfractibus 24 —26, su- 

 perne valde coarctatis, inferne angulatis, serie duplici granulorum ; 

 prope suturam granuloso-carinata. Axis 6 lin. 



Geog. New Guinea ; dredged from a muddy bottom in 8 fathoms. 



The only specimen of this species in the collection has an 

 injured mouth. It is remarkable for its long needle-like shape ; 

 and the upper portion of each whorl being strangulated, and 

 the lower angular and with a series of tubercles, the shell has 

 a very rough and jagged appearance. 



12. T. marmoratus. Testa cylindracea fusca, albo marmorata ; an- 

 fractibus 16 — 18 triseriatim granulosis; seriebus sequalibus, con- 

 fertis, inferiore plerumque albida ; sutura obsoleta. Axis 3 lin. 

 Geog. West Indies. Cab. Gray. 



13. T. eleqans. Testa alba, fusco marmorata; anfractibus 16 — 18
