stinct from any of the trumpet-shaped species, though curiously in- 

 termediate between the Triton variegatus and mistralis. I now de- 

 dicate it with great pleasure to a much-esteemed collector, ■vi'hose 

 cabinet bears interesting testimony of her exce]lent discrimination of 

 species.

 rotundis ; spird suhelatd ; anfractibus costis duplicibus subdistan- 

 tibus undique cinctis, strid unicd elevatd interveniente, costis supe- 

 ris leviter nodosis, costis interstitiisque subdlissime crenulatis ;

This shell is not uncoramon in coUections, though it appears to 

 have been singularly neglected by naturalists. lt presents a most 

 remarkable modification of the Trito7i canaliferus : the entire sculpture 

 of the two species — such as, for example, the double rib, the inter- 

 vening raised line, the t\vo only varices, the profusely \vrinkled colu- 

 melia, the long slightly tvvisted canal, &c — is the šame in both ; but 

 the canaUculated structure of the suturės, which forms so very im- 

 portant a specific character in the Triton canaliferus, is wanting. 

 The Triton Sinensis might therefore be recognised as an example of 

 the Triton canaliferus with the spire pushed out as it were ; or one 

 in which the whorls have not been subject to that peculiar depression 

 •vvhich forms so deep and characteristic a channel round the suture. 



Tbiton grandimaculatūs. Trit. testd ovato-turritd, crassd, in- 

 ferne coarctatd, varicibus tribus ; spird subobtusd ; anfractibus 

 superne angulatis, transversim exiliter striatis et liratis, liris su- 

 peris tuberculato-nodosis ; fuscescente-fulvd, varicibus et columellm 

 parte superiori maculis grandibus nigerrimo-fuscis ornatis ; colu- 

 melld Icevi vel obsolete plicatd ; labro intus dentato, dentibus niger- 

 rimo-fuscis ; aperturcE fauce albd ; canali breviusculo, subascen- 

 dente.

This shell appears at first sight to be nothing more than a casual 

 variety of the Triton totorium ; it \vill be found, ho\vever, upon ex- 

 amination to differ materially. The large tuberculated humps of the 

 Triton lotorium are here represented by regular series of small rounded 

 knobs, -vvhich impart a kind of cancellated structure to the earlier 

 ■whorls which is very characteristic ; the lower part of the shell is not 

 distorted, and the varices, especially at the back, are vividly painted 

 ■with large distinct brown blotches.
