Buccinum , s. str., number of cusps in the single plates variable ; many 
transitional forms exist between the acknowledged species, some of which 
may be hybrids. B. grcenlandicum is first met with north of the Polar 
Circle in Europe, where it occurs at first in company with undatum (L.). 
B. jinmarchianum takes the place of the more southern humphreysianum , 
to be in turn succeeded by hydrophanum. B. grcenlandicum (Chemn.), 
varr. nn. acuta and hybrula, Hammorfest, littoral, var. noar B. sericatum

Kobelt continues his valuable critical monograph of this genus in 
Kuster’s Conch. Cab. pt. 317, pp. 41-72, pis. lxxxiii.-lxxxviii. The fol- 
lowing species are not figured in other works : B. amalice (Verkriizen),
