230 On new Sjpecies o/Conidse and Terebrida3. 



vol. xi. p. 262, I made a few remarks on a species of Terebra 

 which had been referred by Messrs. Deshayes, Hinds, and 

 Beeve (partly) to T. acieulina, Lamarck. Since writing the 

 paper referred to I have had occasion to reexamine this species, 

 and find that it is not in fact the Lamarckian shell. In his 

 diagnosis, which appears almost as if it were extracted from 

 Bom's description of T. cmerea (' Index Musei Vindobonensis,' 

 p. 267) , from the similarity of language, he gives " albido- 

 cinerea " as the colour of the species, which evidently in no 

 way applies to the present species, which is of a more or less 

 ashy-brown colour, banded with white beneath the suture, and 

 also longitudinally streaked with brown, and has a white zone 

 around the last whorl a little below the middle, which is 

 also distinctly seen within the brown aperture. 



M. Deshayes, in the second edition of Lamarck's ' Animaux 

 sans Vert^bres,' vol. x. p. 250, remarks that Lamarck was 

 wrong in changing Born's name cinerea to that of acicuUna 

 if his shell was the same as that of this author, and he considers 

 Born's species identical with that described by Lamarck under 

 the name of Terebra coirulescens. This, however, is a palpable 

 mistake \ for the latter is a smooth shell without any striation or 

 plication beneath the suture, differently coloured, and has the 

 sutures indistinct (" suturis obsoletis," Lamarck), which 

 arises from the fact of the whorls being encircled by a narrow 

 callosity just above, but contiguous to, the suture, which 

 peculiarity induced me to found the subgenus Impages for 

 this and a few other species possessing the same charac- 

 teristic. 



The synonymy of T. ccerulescens and T. cinerea is as 

 follows : —
