88 THE NAUTILUS. 



Figure 27, NATICA IMMACULATA Totten ; all three must be re- 

 ferred to the genus Polinices. 

 Figure 29, BELA DECUSSATA Couthouy becomes Lora decus- 



sata Couthouy. 

 Figure 30, COLUMBELLA LUNATA Say becomes Alia lunatcu 



Say 

 Figure 31, COLUMBELLA AVARA Say becomes Anachis avara 



Say. 

 Figure 32, NASSA OBSOLETA Say becomes Alectrion (Ilyan- 



assa) obsoleta Say. 

 Figure 33, NASSA TRIVITTATA Say becomes Alectrion (Tritia) 



trivittata Say. 

 Figure 35, BUCCINUM CINEREUM Say is now Urosalpinx 



cwierea Say. 



Figure 36, Fusus ISLANDICUS Gmelin. This should bear the 

 name Coins stimpsonii Morch. It is interesting, in this 

 connection, to call attention to the fact that an error has 

 slipped into Johnson's " Fauna of New England ", in 

 his citation under this species on page 137. He cites 

 the type locality as as Faero. The fact is, Morch states 

 at the reference cited that Fusus stimpsonii (F. comeus 

 Say, Amer. Couch.), is the American species; that the 

 Faero specimens differ from it, are thinner shelled, and 

 have flatter whorls than F. stimpsonii. Say misidentified 

 this as the corneus of Linnaeus. 



Figure 37, Fusus PYGMAEUS Gould is C&lus pygmaeus Gould. 

 Figure 38, Fusus DECEMCOSTATUS Say is now Chrysodomus 



decemcostatus Say. 

 Figure 41, EANELLA CAUDATA Say is now known as Eupleura 



caudata Say. 



Figure 46, MELAMPUS BIDENTATUS Say is now generally con- 

 sidered to be Melampus lineatus Say. 



There have been so many changes and so much discussion 

 in the preceding remarks that it might seem as if Professor 

 Morse's paper had been criticised. I wish here to dispel any 

 such impression. All that we have attempted is to bring up 

 to date an involved nomenclature that will render his con- 

 tribution the more intelligible to those who do not have thel 

 mass of literature necessary to effect these needed changes.
