Sipho (Klein), Morch, Cat. Toldi, 1852, p. 104 {non 0. Fabricius, 

 1823, nee T. Brown, 1827, 1833, 184-1). 



Shell thin, usually fusiform, whorls rounded, typically smooth 

 aud striated ; spire elevated ; columella plain ; canal produced 

 and often recurved. 



The term Sipho, commonly employed for this genus, was first 

 proposed by Klein,' but that author's work, being pre-Linnean, 

 cannot be accepted. The name was brought on by Morch in 

 1852, as above indicated. But in 1847 Beck had already 

 proposed Tritonofusus, which is synonymous with Sipho, Klein, as 

 interpreted by Morch, and must therefore take priority. 



Even if that were not the ease, Sipho (Klein), Morch, could not 

 be adopted, as T. Brown had employed the term in 1827.^ If 

 that be objected to on the ground that the work in which it was 

 suggested was merely a collection of plates without descriptions, 

 Sipho [Si/pho), Brown, must fall in synonymy with Puncturella, 

 Lowe, 1827, though Brown subsequently attempted^ to establish 

 his term. 



In reference to Sipho, 0. Fabricius, 1823 (not 1822, as commonly 

 quoted), that name was proposed in an auction catalogue,* referring 

 to the books, natural-history specimens, etc., which belonged 

 to Bishop Fabricius.* Murex infundihulum, Gmel., appears to be
