 The name ananas, as applied to this species, dates from Pallas, 

 1766, who described it very well indeed. But the name, as used 

 previously by Linne (Syst., ed. x, p. 797) was particularly applied to 

 a Gothland fossil coral of the genus Acervidaria. So it should, with- 

 out doubt, be dropped for this living species, to which it has been 

 so long applied. However, this name has also been applied, by the 

 earlier writers, to other existing species, so that its synonymy is 

 complex. Fortunately the early name fragum is available and has, 

 appai'ently, not often been applied to other species, so that its use 

 for this one can hardly lead to any confusion. My own experience, 

 based on a study of large numbers of specimens, living and dead, is 

 in accord with that of Mr. Vaughan, as to the necessit}^ of uniting 

 the several forms described by Duch. and Mich, and by Quelch as
