74 M, o. A. L. morch's review of the vermetidtE. [Feb. 11, 



noduloso Kris destituto ; apertura circularis, suhsoluta ; color 

 albus, punctis ferrugineis paucis ohsoletissimis ; faucibus juxta 

 aperturam macula castanea ; hie illic lapillis agglutinatis. 

 (Descriptio ex specimine original! Musei Wratislaviensis.)

 Hah. 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.
