The nonienclatorial status of the genus Terebra and its subdivisions has been 

 very confused. This is largely due to an error of Quoy and Gaimard, who figured 

 Terebra subulata with the eyes wrongly placed, thus leading the brotliers Adams 

 into the mistake of dividing the geuus ou this character. Hinds, iu placing the 

 description of his subgenus Myurella after, instead of before the description of the 

 three species he referred to it, has betrayed several careless authors into error. 

 A few notes on the nomenclatorial history may make the changes required more 

 easily understood. 



The shells of this genus were called Strombus by Euniphius, and the name 

 Terebra, introduced by Adanson for a heterogeueous assembly, was adopted bino- 

 mially by Bruguiere, iu 17S9, and a type, T. subulata (Liune) supplied by Lam- 

 arck ten years later. The name Acus was proposed in the auonymous Museum 

 Calonniauum in 1797, but according to Slierborn had been used by Edwards for 

 a fish in 1771. The name Vertagus, proposed by Link as a substitute for Terebra, 

 iu 1807, is an exact syuonym of Terebra as treated by Lamarck. Terebrum 

 Montfort, 1810, is based on the type species of Terebra Lamarck, and Terebraria 

 Rafiucsque, is another change arbitrarily proposed for the same genus. Subula 

 Schumaciier was proposed as a substitute for Terebra, because that author thought 

 the shells " had more the form of an awl than of an auger." He divided the 

 group into two sections, of which the first was named Acus by Gray, in 1S47, 

 with the type T. tiiaculata, for which Oxymeris was substituted by Dall, iu 1900, 

 Acus being prcoceu|)ied. The second section of Schumacher typified by Terebra 

 dimiiliata will retain Schumacher's name in a sectional sense. 



The name Turricula (for T. subulata'), alleged by Ilcrrmannsen to have been used 

 by J. Hermann in his "Tabula" iu 1773, docs not appear in that work, tliough 

 the plural form is used (not iu a generic sense) to cover a subdivision of the 

 heterogeneous genus Bucciiinm. 



Hind.s proposed, in 1844, for three species of Terebra having mostly spiral 

 sculpture, strongly nodulous sutural baud, many slender whorls, and a thickened
