CONUS Supp.— Plate III. 



The cold Cone. Shell stoutly ovate, rather thick, 

 transversely finely and delicately ridged, ridges 

 obsoletely granulated towards the base, spire three- 

 grooved ; pale straw-colour, base and apex violet. 



Hah. ? 



There is a peculiarity in the transverse ridges of this 

 species becoming slightly granulated towards the base, of 

 which it is impossible to give an idea in a figure ; the 

 upper portion of the shell is smooth and of rather solid 

 growth ; the whole is of a pale yellow colour having the 

 base and apex tinged with dark violet. 



Species 285. (Mus. Cuming.) 



Conus infrenatus. Con. testa oblongd, tenia, subinjlatd, 

 Icevigatd, spird depressiusculd suturis rudibus ; roseo- 

 albidd, tteniis fuscescente alboqne articidatis, subdistan- 

 tibus, cingulatd, apice roseo. 



The bridled Cone. Shell oblong, thin, somewhat in- 

 flated, smooth, spire rather depressed, sutures rude ; 

 rose-white, encircled with rather distant fillets of 

 articulated light brown and white, apex pink. 



Hob. ? 



Related in some degree to the C. aplustre, but certainly 

 distinct ; it is of a light rather inflated growth, of a pale 

 rose tint, encircled throughout with rather distant conspi- 

 cuous articulated fillets. 



Species 286. (Mus. Cuming.) 

 Conus trigonus. Con. testa subtrigono-ovatd, basin versus 

 mlcatd, spird peculiariter depressd, quinque-sulcatd, 

 apice acuto ; albd, rnfo-fusco tinctd et fasciatd, taniis 

 numerosis eximie articidatis angustis undiqite cingula- 

 td, spird tessellatd. 

 The triangular Cone. Shell somewhat triangularly 

 ovate, grooved at the base, spire peculiarly depressed, 

 five-grooved, sharp at the apex ; white, stained and 

 banded with reddish-brown, and encircled with nu- 

 merous narrow delicately articulated filaments, spire 

 tessellated. 



Hab. ? 



Remarkable for its broad flattened spire ; it approaches 

 somewhat to the 0. Japonicus, Bruguiere, known oniy by 

 the figure in the Enc. Me'th. pi. 330. f. 3. but cannot be 

 pronounced to be the same.
