Differing from other shells of similar general appearance in the 
narrow sulci of the middle and lower part of the last whorl. 
¥ Conus corrvueatus. (Pl. XXII. fig. 7.) 
C. testa parva, acuminata, liris duplicatis, subrugosis, granulatis et 
interstitiis minutissime sculptis cincta; supra et infra medium pal- 
lide griseo fasciata, strigis minutis fuscatis variegata; spira acu- 
minata; anfractibus cancellatis, acute angulatis, angulis concinne 
Susco punctatis. 
Hab. ? 
A more slender and much more finely sculptured shell than C. 
verrucosus, with the edges of the whorls neatly spotted with brown. 

Conus SOWERBYI, var. SUBZQUALIS. (PI. XXII. fig. 5.) 
C. testa utrinque subequaliter acuminata, medio acutangulata. 
Hab. China Seas. 
Described at first for this paper as a new shell, being remarkable 
for the length of its spire. It resembles C. precellens in form, but 
with less numerous ribs, and having the interstices very beautifully 
sculptured. The spire nearly equals the body of the shell in length. 
In C. acutangulatus the sulci are few, aud the intervening spaces flat. 
Conus sEmisutcatus. (Pl. XXII. fig. 13.) 
C. testa parva, utrinque acuminata, levigata, fumeo-fuscata, infra 
medium distanter plano-sulcata, versus extremitatem acuminatim 
coarctata ; spira acutissime angulata, concavo-acuminata; anfra- 
ctibus plano-concavis, versus apicem moniliferis. 
Hab. ? 
A little brown shell with whorls beaded near the apex. 
Conus GeMMutatus. (Pl. XXII. fig. 8.) 
C. testa parva, albida, utrinque subequaliter acuminata, costellis 
rotundis subrugosis lirata, interstitiis profundis, striis tenuibus 
longitudinaliter sculpta ; spira exserta, producta, valde acuminata ; 
anfractibus numerosis, papillis rotundis regularibus gemmuli- 
Sormibus coronatis ; apertura angusta, labio postice profunde 
sinuato. 
Hab. China Seas. 
A most wonderful fusiform little Cone, with a very produced spire, 
the whorls of which are beautifully beaded with gem-like papille. 

Conus RARIMACULATUS. (PI. XXII. fig. 4.) 
C. testa albida, ucute angulata, levigata, hic illic castaneo macu- 
lata; spira obscure cancellata, acuminata, flammulis castaneis 
picta. 
Hab. China Seas. 
A whitish smooth shell, with very few spots of chestuut. 
STROMBUS MIRABILIS. (Pl. XXI. fig. 4.) 
S. testa elongato-fusiformi, ad spiram et anfractum ullimum casta-
