alba secunda ornatus; anfr. 124 medio angulati, longitudinaliter 
flexuose obsolete plicati, plicis superne leviter nodulosis, medio

This is a very pretty species, and belongs to the same 
group which includes P. Metcalfec, Angas, and some others. 
19. Bela tessoensts, sp. nov. 
Testa ovato-fusiformis, sordide albida; anfr. 6 convexi; primi 2 
leeves, ceeteri plicis longitudinalibus subacutis (in anfr. ultimo 14 
flexuosis, infra medium sensim evanescentibus) instructi, et striis 
confertis elevatis (una quam ceteris majore anfractuum medium 
succingente, in ultimo obsoleta) inter et supra costas ornati ; 
apertura ovato-oblonga, subangusta, longitudine spiram sequans, 
intus fuscescens; columella levis, alba, vix tortuosa; labrum 
tenue, superne leviter sinuatum ; canalis brevissimus, latiusculus,

Hab. South-east of Yesso, lat. 42°58! N., long. 104° 24! E., 
at a depth of 43 fathoms ; bottom, sand and mud. 
This very beautiful species is well characterized by its 
convex whorls, which are neatly plicated longitudinally—and 
especially by the close and fine spiral liration with which the 
entire surface is ornamented, one lira larger than the rest 
encircling the middle of each calnceal 
20. Murex (Chicoreus) adustus, Lamk.; Conch. Icon. 11. f. 29; 
Kiener, Coq. Viv. pl. 33. f. 1. 
Murex despectus, A. Ad. Proc. Zool. Soe, 1853, p. 72. 
Hab, Ooshima. 
Having carefully compared the type of despectus with spe- 
cimens of Lamarck’s species, I do not hesitate to place the 
former as a synonym; for I cannot trace any differences. 
Supposing the locality “ West Indies,” quoted by Mr. Adams, 
to be correct, then this is a remarkable instance of wide 
geographical range.
