38 MUREX. 



intus creiiato, spira breviuscula, anfractibus angulatis. — The 

 varices are fewer than in M. liratus, with a large tubercle 

 in most cases, between. 



173. liratus, f. 173, A. Adams. — Testa rugosa solida 

 quadrigona, fusca, spiraliter lirata, varicibus octonis, nodu- 

 losis, castaneis, antice vix frondosis ; spira pyramidata, elevata, 

 anfractibus obtuse angulatis ; apertura subovata, margine 

 externo crenulato et dentato ; canali brevissimo, lato.— The 

 varices are numerous, solid, and plain, excepting two or three 

 very small spinose fronds near the base ; the angle falls 

 below the middle of the shell, making the spire pyramidal 

 and the canal very short. 



174. Adamsi, f. 234, Sowerby. — Testa angulata alba solida 

 brevis ventricosa, spiraliter leviter lirata ; varicibus octonis 

 crassis lseviusculis, ad canalem subdigitatis, ad marginem 

 disci imbricatis ; apertura magna, pyriformi canali brevius- 

 culo, lamina discoidea latiusculo. — Smoother than the others 

 of this group. 



175. tenuis, f. 174, Sowerby. — Testa breviter fusiformis, 

 tenuis, lseviuscula, pallide fulva castaneo fasciata, spiraliter 

 lirata, inter varices plicatim unituberculata ; spira pyramidata, 

 acuminata, anfractibus angulatis ; varicibus quaternis tuber- 

 culatis, antice subfrondosis ; canali brevi, lato. — This pretty 

 little species of which I have only seen one specimen, at first 

 sight reminds one of M. vibex, but differs from that doubtful 

 rnurex in having regular varices distinguishable from the 

 intermediate tubercles, and a nearly closed canal. 



176. pudicus, f. 243, A. Adams. — Testa brevis, fere alba, 

 scabra ventricosa angulata, spiraliter lirata, interstriata, 

 varicibus senis crassis rotundis approximates, ad canalem 

 imbricatis, spira pyramidata, anfractibus angulatis, supra 

 angulum subplanatis, apertura angulata, labio externo crenato, 

 intus lirato ; canali brevi, lato, lamina discoidea excavata. — 

 A short angular shell without fronds on its varices. 



177. asper, f. 244, A. Adams. — Testa alba, scabrosa, ventri- 

 cosa, brevis, spiraliter serrato-lirata ; anfractibus senis, robustis, 

 aculeatim frondosis, ad canalem subexfoliatis, spira brevius- 

 cula, anfractibus superne angulatis, apertura subrotunda, 

 margine externo serrato, intus subdentato, canali brevissimo, 

 lato, lamina discoidea excavata. — Resembling M. pudicus, 

 but more frondose.
