strie, which appearance is produced by the numerous longi- 
tudinal Jirations in the interstices between them. 
Pleurotoma (Clavus) quadrilirata. 
Testa fusiformi-ovata, alba, inferne ad suturam et in anfr. ultimo 
circa medium linea saturate roseo-fusca cincta; anfract. 9, supra 
concavi, infra convexiusculi, costis subrectis superne versus sutu- 
ram undulatam evanidis (in anfr. ultimo 7 vix ad basim continuis, 
ultima maxima) instructi, et circa dimidium inferius liris spirali- 
bus 4 supra costas preecipue prominentibus cincti; anfr. ultimus 
infra liras spiraliter crebre striatus, infra ineam fuscam dilute roseo 
late zonatus ; apertura parva, sordide albida, longitudinis teste 
2 equans; columella recta, callosa, ad suturam tuberculata ; 
sinus mediocris ; canalis brevissimus, levissime recurvus.

The deep pinkish-brown line above the suture is most 
apparent between the ribs. The four lirations on the ribs are 
rather acute and prominent, and are only on the lower half 
of the whorls. 
Pleurotona (Clavus) interstrigata. 
Testa acuminato-pyramidalis, flavida, inter costas roseo-fusco stri- 
gata; anfract. 73, primi 13 leves, ceteri superne leviter con- 
stricti, inferne convexiusculi, costis crassis superne ante suturam 
evanidis (in anfr. ultimo 10 basi desinentibus) instructi, liris spi- 
ralibus supra costas subtubercularibus, in interstitiis fere obsoletis, 
cincti (liris in anfr. penult. 4, in ultimo circa 12), undique minu- 
tissime spiraliter striati, sutura undulata sejuncti; apertura intus 
flavescens, longitudinaliter fusco-roseo strigata, long. totius —+- 
adeequans ; columella callo prope suturam tuberculato induta ; 
sinus parvus ; canalis brevissimus.

Hab. St. Thomas and St. Vincent, West Indies. 
Each of the longitudinal ribs may be said to be composed 
of four transverse nodules, and those on the body-whorl are 
bifurcate from the middle downwards. ‘The lire on the body- 
whorl below the four principal ones are only slightly inter- 
rupted in the interstices between the ribs. 
Pleurotoma (Clavus) hottentota. 
Testa oblonga, subturrita, fuscescens, zonis duabus albis (in anfr. 
ultimo 3) in interstitiis inter costas interruptis ornata; anfract. 
8, superne leviter excavati, inferne convexiusculi, costis obliquis, 
superne versus suturas evanidis (in anfr. ultimo 12 infra medium
