FUSUS. 7 1 



apertura magna, intus lirata, margine rude crenato. — Broad, 

 rough, of a burnt brown colour. 



7. versicolor, f. 22, Gmelin. — Testa ventricosa, spiraliter 

 subacute lirata, pallide fulva, distanter longitudinaliter 

 costata, inter costas castaneo strigata, ad angulum macu- 

 lata, spira breviuscula, anfractibus 10, rotundis vel medio 

 leviter angulatis, ultimo subelongato ; apertura subovata, 

 intus crenulato gradatim in canalem decurrente ; canali 

 crasso. — Our fig. 22 represents a medium degree of angula- 

 tion. The broader and more angular was taken by Rve. for 

 distans, Lam. The original of Chemn. is narrow and round- 

 whorled. 



7*. distans, f. 162, Lam. — For this species we figure a 

 shell in Mr. Hanley's collection, which closely resembles that 

 figured by Kiener from Lanarck's collection. 



8. undatus, f. 6, Gmelin. — Testa magna ponderosa sub- 

 lsevigata, spiraliter leviter striata, anfractibus supra medium 

 subangulatis, tuberculis maximis undatis ; apertura parva, 

 margine crenulato ; apice acuminato, canali breviusculo, 

 subtortuo. — The large tubercles being of solid structure 

 makes this shell the heaviest of its tribe. 



9. similis, f. 44, Baird. — Testa albida, rugosa, spiraliter 

 rudissime costata, ad angulum anfractuum distanter nodis 

 maximis munita. — This species has much the form of 

 F. undatus and F. similis, but contrasts with both, especially 

 the former, in the roughness of surface and thickness of ribs. 



10. NODOsorLiCATUs, f. 45, Dunker. — Testa albida lata sub- 

 rugosaliris tenuibus cincta ; spira breviter conica, anfractibus 

 9 angulatis, ad angulum nodosis ; apertura subangulata, intus 

 lirata, margine crenato ; canali rectiusculo. — Kesembling F. 

 undatus and F. nodoso-plicatus, but differing from the former 

 in being more sharply tuberculed, and from the latter in 

 being much smoother. 



11. Beckii, f. 18, Jonas. — Testa alba ventricosissima, 

 planulatim spiraliter costata ; spira brevi, acuminata, an- 

 fractibus acute costatis, depressis, latis, ultimo latissimo, 

 canali angusto, tortuo ; apertura magna intus et ad marginem 

 crenata. — The whorls are depressed and wide, the spiral ribs 

 are slightly flattened, and the last is suddenly contracted 

 where it passes into the narrow and tortuous canal. 



12. nobilis. f. 4, Reeve. — Testa alba, ventricosa, spira
