SHELLS COLLECTED liN JAPAN, '295 



This Lymnea approaches Lymnea ovata, but has a shorter spire, which is less exserted, less 

 acute, the whorls more rounded, and differs in color. The columella lip is reflected on the body 

 whorl. 



PURPURA SEPTENTRIONALJS. 



Plate 5, figs. 16, 17. 



Purpura, testa, subfusiformi, ovata, crassa, ponderosa ; basi subcanaliculata et recurva ; 

 anfractibus laBvibus, transversim obsolete liratis ; apertura parva, labro intus obscure denticu- 

 late ; castaneo-fusca, intus alba. 



Shell somewhat fusiformly ovate, thick, ponderous, slightly channelled and recurved at the 

 base ; whorls smooth, transversely obsoletely ridged ; aperture small, lip obscurely denticulated 

 within ; chestnut brown, interior white. 



Habitat, Sitka, on authority of Eeeve. 



Eeeve Conch. Iconica, pi. 10, fig. 50. 



There were several specimens of this interesting shell brought home, but without any habitat 

 being attached. Whether it was found in the Japanese waters, therefore, is uncertain. 



BULLIA PERRYI. 



Plate 5, figs. 13, 14, 15. 



Testa, ovato globulosa, tenuicula, basim versus inflata, spira breve, acuta, suturis impressis, 

 anfractibus lasvigatis, flavido, cinerea, aperturas fauce rubiginosa. 



Shell ovately globulose, rather thin, inflated towards the base, spire short, acute, sutures 

 impressed, whorls smooth, color yellowish ash, interior of aperture rusty brown. 



Habitat, Bay of Yedo. 



It is extremely difficult to place this shell. It does not agree in many of the characteristics 

 of the genus Bullia, but comes closer to it than to any other. It looks like a Cymba on the first 

 glance, but has no plaits on the columella. There was only one found, and that was taken by 

 the dredge.
