The nomenclatorial 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 brothers Adams 
into the mistake of dividing the genus on this character. Hinds, in 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 Rumphius, and the name 
Terebra, introduced by Adanson for a heterogeneous assembly, was adopted bino- 
mially by Bruguière, in 1789, and a type, T. subulata (Linné) supplied by Lam- 
arck ten years later. The name Acus was proposed in the anonymous Museum 
Calonnianum in 1797, but according to Sherborn had been used by Edwards for 
a fish in 1771. The name Vertagus, proposed by Link as a substitute for Terebra, 
in 1807, is an exact synonym of Terebra as treated by Lamarck. Terebrum 
Montfort, 1810, is based on the type species of Terebra Lamarck, and Terebraria 
Rafinesque, is another change arbitrarily proposed for the same genus. Subula 
Schumacher 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 1847, 
with the type 7. maculata, for which Oxymeris was substituted by Dall, in 1900, 
Acus being preoccupied. The second section of Schumacher typified by Terebra 
dimidiata will retain Schumacher’s name in a sectional sense. 
The name Turricula (for T. subulata), alleged by Herrmannsen to have been used 
by J. Hermann in his “Tabula ” in 1773, does not appear in that work, though 
the plural form is used (not in a generic sense) to cover a subdivision of the 
heterogeneous genus Buceinum. 
Hinds proposed, in 1844, for three species of Terebra having mostly spiral 
sculpture, strongly nodulous sutural band, many slender whorls, and a thickened
