78 CYLLENE. 



spiraliter sulcata, lcmgitudinaliter distante costata; spira pyrami- 

 dali, lirata; sutura fusco-lineata. — Differing from the preceding 

 in being transversely sulcated ; the longitudinal ribs are thick, 

 angulated, and few, a single dark line of colour marks the suture. 

 Hab. ? 



4. unimaculata (f. 81, 32), A. Ad. MS. — C. testa C. sul- 

 cata simili, sed latiori ; anfractu ultimo breviori, macnlo magno 

 ad unguium picto. — Shorter and wider than C. sulcata, and with 

 a large brown spot on the upper angle of the last whorl, which is 

 short in proportion. Hab. ? 



5. lugubris (f. 7, 8, 9), A. Ad. Toy. Samarang. — C. testa 

 ovata, crassa; spira acuta; anfractibus undique creberrime sul- 

 catis, superne tumidis, subtiliter noduloso-plicatis ; intense cas- 

 tanea, labio albo, anfractuum margine superiori albivariegata. — 

 Strongly sulcated throughout, of a dark-brown colour, finely 

 plicated at the angle of the whorls; the columella white, produced 

 and turned upwards at the back. Sooloo Islands. 



6. Oweni (f. 19, 20), Gray, MS. B. M.—C. testa ovata, 

 subangulata, pallida, fusco-variegata, subdistanter spiraliter sul- 

 cata; labio externo superne depresso, intus tenuiter striato.— A 

 rather large species, resembling C. lugubris, but of a pale colour 

 variegated with brown, excepting the spire, which is dark. The 

 spire is shorter, the grooves are coarser, and the upper part of 

 the body-whorl and outer lip angularly depressed. Hab. ? 



7. pallida (f. 21, 22), A. Ad. — C. testa parva, pallide 

 fulva, obscure liueis articulatis ornata, supra et infra, spiraliter 

 sulcata, longitudinaliter tenuiter plicata ; anfractibus ad suturain 

 moniliferis. — A rather small, pale species, varied with articulated 

 lines, beaded at the suture, and spirally sulcated above and below. 

 West Africa. 



8. plumbea (f. 23, 27, 28), Soivb. Thes.- — C. testa, caeru- 

 lescente, subangulata, supra et infra spiraliter sulcata, longitu- 

 dinaliter distante plicata, seu planata; anfractu ultimo superne 

 depresso, ad suturam albo-marginato ; apertura intus fusca, validi 1 

 sulcata, labio externo et columella flavidis. — The variety f. 27, 

 28, although without ribs on the body-whorl, presents so many 

 characters in common with the type, that I think the variation is 

 accidental. Hab. ? 



9. okientalis (f. 12, 13), A. Adams, Pro. Zool. Soc. 1S50. 

 — C. testa ovato-fusiformi, albida, maculis luteo-fuscis ornata,
