_pallide carinati vel incrassati, infra carinam leviter constricti,

The bifurcation of the ribs on the body-whorl is very re- 
markable. The ribs are broader at the upper ends than in- 
feriorly. Three or four of the spiral lirations are coarser than 
the rest, and are thickened on crossing the ribs. The palish 
keel beneath the suture is a little undulating and spotted with 
brown. 
Pleurotoma (Crassispira) flavocarinata. 
Testa ovata, saturate fusca, infra suturam carina validissima flava 
ornata; anfract. 9, superne valde carinati, infra carinam sulco 
angusto arati, infra suleum costis parvis 18-20 (in anfr. ultimo 
fere ad basim continuis) instructi, inter costas spiraliter striati ; 
anfr. ultimus liris ad 12, quarum superlores sex supra costas nodu- 
losee sunt, succinctus, striis paucis spiralibus inter liras ornatus ; 
apertura parva, longitudinis totius 2 adequans; labrum infra 
carinam sinu parvo subamentiformi fissum; columella rectius- 
cula, callo tenui amicta ; canalis perbrevis, vix recurvus.

This species is very easily recognizable. The uniform 
deep brown or chestnut colour, the very stout yellow keel 
around the upper part of the whorls, and the little numerous 
ribs on the lower are the principal characteristics. The keel 
is edged above, or, in other words, is not quite contiguous 
with the suture. The sculpture is very like that of P. discors, 
Sowerby. 
Pleurotoma (Crassispira) latizonata. 
Testa solida, acuminato-ovata, dilute rubra, albo late fasciata; an- 
fract. 8, planiusculi, costis exilibus circa 24 et liris spiralibus 4 
(in anfr. ultimo 14) granulate cancellati, parte superiore tertia 
haud spiraliter lirati, ubique spiraliter minute striati; apertura 
parva, longitudinis totius 7% adequans; columella juxta sutu- 
ram valde tuberculata; labrum crassissimum; sinus parvus, 
minime profundus ; canalis brevissimus. 
Long. 9 mill., diam. 33.
