74. M.O.A.L, MORCH’S REVIEW OF THE VERMETID#, [Feb. 11, 
noduloso liris destituto; apertura circularis, subsoluta ; color 
albus, punctis ferrugineis paucis obsoletissimis ; faucibus juxta 
aperturam macula castanea; hic illic lapillis agglutinatis. 
(Descriptio ex specimine originali Musei Wratislaviensis. ) 
Vermicularia scabra, Gravenh. Tergest. p. 55. no. 2. 
Hab. Ignot.; Lusitania? 
The locality is very doubtful, as most of the species described in 
the work quoted, according to the original specimens, for the loan 
of which I am indebted to Professor Grube, are from the West Indies. 
The brown spot in the aperture and the size of the shell remind one 
of Siphonium nebulosum ; but the sculpture is quite different, and in 
this respect it approaches to the next species. In the collection of 
Charles VIII. is a specimen with a long apertural tube, probably 
from Portugal, which is very like it. |
