vodulis flavicantibus ornata; anfract. 10-11 supra paululum ex- 
cavati, medio angulati, superne ad suturam carina parva, pallida, 
subnodosa cincti, circa medium nodulorum flavicantium circiter 
15 serie ornati, liris spiralibus ad 6 (inferioribus duabus infra 
nodulos sitis quam ceeteris majoribus, tuberculisque parvis munitis) 
succincti; anfr. ultimus liris a nodulis descendentibus aliisque 
spiralibus concinne nodose clathratus ; apertura fusca, intus lirata, 
longitudinis totius + paulo superans ; canalis perbrevis, latus ; 
sinus latus, supra nodulorum seriem situs. 
Long. 13 mill., diam. 4. 
Hab, Ooshima Harbour, 8 fathoms; Tsusima Strait, 9 
fathoms; Matoza Harbour, 6 fathoms. 
The lirations within the aperture are more distinct in some

16. Pleurotoma ( ?) tuberosa, sp. nov. 
Testa elongata, fusiformis, turrita, albida, apice fuscescens, strigis 
fuscis inter costas variegata; anfr. 12, primi duo vitrei, politi, 
globulares, ceeteri convexiuscul, infra suturam undosam carinatam 
leviter constricti et canaliculati, infra canalem costis crassis sub- 
obliquis (in anfr. superioribus nodulosis) (una hie illic quam 
ceteris majore tuberosa et fusca) imstructi, spiraliter preecipue 
inter costas striati; anfr. ultimus circa peripheriam albo zonatus, 
costis ad 10 versus basim obsoletis, una post labrum maxima, 
fusca; apertura parva, alba, zonis duabus interruptis macularum 
externarum intus variegata, longitudinis totius } equans ; colu- 
mella callo crassiusculo amicta, ad suturam tuberculata; canalis

Long. 22 mill., diam. 7. 
Hab. Ooshima Harbour, 8 fathoms; Matoza Harbour, 6

This ee possesses the general aspect of varicosa, Reeve ; 
it is, however, distinct. ‘The brown swellings or varices (in 
varicosa white), the brown apex, small aperture, and white 
band around the periphery easily separate this form. 
17. Pleurotoma ( ?) erosa, Schrenck.

Lande, pl. 17. f. 5-7. 
Hab. Nemero, East Yesso, 3 to 4 fathoms; off Cape Blunt,
