426 On Gasteropoda collected in Japanese Seas. 
44, Admete ovata, sp. nov. 
Testa ovata, tennis, semipellucida ceeruleo-alba ; anfractus 4—5 con- 
vexi, supremi 2-3 erosi, penultimus longitudinaliter oblique plica- 
tus, plicis superne suturam non attingentibus et spiraliter striatus, 
ultimus maximus, subglobosus, striis spiralibus circiter 20 in- 
sculptus; apertura ovata, longitudinis totius 8, adeequans ; colu- 
mella arcuata, callo tenuissimo induta, basi oblique truncata. 
Long. 64 mill., diam. 34; apertura long. 4 mill., diam. 2. 
Hab. Lat. 42° 52’ N., long. 144° 40’ E., 48 fathoms, 
sand and mud; temperature at bottom 37°-39°. 
This species is peculiar for its ovate form and very short 
spire. Only the penultimate whorl appears to be plicated. 
45. Admete globularis, sp. nov. 
Testa parva globularis, tenuis, nivea; anfractus 43, primi tres parvi 
convexiusculi sutura leviter canaliculata sejuncti, ultimus globosus 
magnus, omnes spiraliter tenuissime sulcati, apertura aliquanto 
magna, subpyriformis, longitudinis totius fere ? equans; colu- 
mella callo tenui lato supra anfractum producto amicta, versus 
basim oblique truncata; labrum tenue, simplex. 
Long. 4 mill., diam. anfract. ultimi 2. 
Hab. Lat. 42° 52' N., long. 144° 40’ E., at a depth of 48 
fathoms, on a sandy bottom, with a temperature of 37°-39°. 
This is a very remarkable species, and unlike any shell which 
has ever come to my notice, and probably may eventually be 
placed in a distinct genus. It is in form very much like Cassis 
saburon ; and the truncature of the columella resembles that of 
Verena crenocarina in the Melaniade, or of the genus Achatina 
among the Pulmonata. The thin callous deposit extends from 
the juncture of the labrum with the body-whorl to the end of 
the columellar truncation, and spreads out some distance over 
the whorl. 
46. Oliva (Porphyria) mustelina, Lamk. ; Conch. Icon. vi. f.23. 
Hab. East of Niphon, 3 fathoms, soft mud. 
47. Olivella fulgurata, Adams & Reeve. 
Oliva fulgurata, Adams & Reeve, Voy. Samarang, pl. x. f. 12. 
Oliva Fortunei, A. Adams, MS. in Coll. Cuming. 
Hab. Yamada Harbour, lat. 39° 32' N., long. 141° 53’ E., 
in 7 fathoms, bottom sand and broken shells. 
The Japanese specimens are of a pale horny colour, varie- 
gated with undulating chestnut markings.
