600 MR. G. B. SOWERBY ON NEW SPECIES OF SHELLS. [Nov. 3, 



Hab. Hongkong (CutAill). 



The characters of this species are much the same as those of S. 

 Septimus (Duclos), of which Mr. Cuthill has sent me several speci- 

 mens from the same locality ; but the form is very different, the 

 latter being a narrow shell of the form of S. succinctus (Linn.), which 

 is found in Ceylon. 



4. Columbella (Anachis) sinuata, sp. nov. (Plate LXXII. 

 figs. 2, 2 a.) 



C. testa fusiformi, rufo-fusca, cceruleo-albo et brunneo variegata, 



tenui, pellucida ; spira acuminata ; anfractibus 9, planalo- 



conveocis, Icevibus, longitudinaliter reyulariter valide costatis ; 



costis ad anfractum ultimum, versus marginem medio tubercu- 



latis ; apertura oblonga, intus ccerulea, costata ; columella 



corrugata, tenuiter encaustica ; canali brevi, pro/undo, recurvo ; 



labio externo superne elevato, expanso, incrassato, medio sinu 



lato pro/undo emarginato : long. 1 7, lat. 9 mill. 



Shell fusiform, reddish brown, variegated with bluish white and 



dark brown, thin, transparent ; spire acuminated ; whorls nine in 



number, flatly convex, smooth, strongly ribbed longitudinally ; the 



ribs on the last whorl towards the margin tuberculated in the middle, 



transversely ribbed at the base ; aperture oblong, interior blue, ribbed ; 



columella wrinkled, covered with a transparent, shining enamel ; 



canal short, deep, recurved; outer lip thickened and expanded at 



the upper part, and with a broad deep sinus in the middle. 



Sab. Upper California. 



A very remarkable little shell, almost generically distinct from any 

 hitherto known species ; I think, however, it truly belongs to the 

 section Anachis (H. & A. Adams). The sinus is almost like that 

 of a Pleurotoma ; only it is in the middle of the lip. 



5. AMPtrLLARiACATAMARCENSis, nov.sp. (Plate LXXII. fig. 4.) 



A. testa subglobosa, imperforata, solidiuscula, lutescenti-alba, 

 atrqfusco fasciata, undique subtilissime reticulata ; epidermide 

 tenui, lutescente; spira exserta, parviuseula, subacuta; anfrac- 

 tibus convexis ; apertura ampliuscula ; columella callosa, fusco 

 suffusa ; labio externo subincrassato, vix reflexo : long. 70, lat. 

 60 ; apert. long. 50, lat. 35 mill. 

 Shell rather globose, imperforate, rather solid, yellowish white, 

 banded with dark brown, throughout very finely reticulated ; epider- 

 mis thin, yellowish ; spire rather small, exserted ; whorls convex ; 

 aperture rather wide ; columella thickened, suffused with brown ; 

 outer lip somewhat thickened, scarcely reflexed. 

 Hab. Catamarca (on the Andes of Peru). 

 A fine species of the type represented by A. columellaris.
