T. ephippiiim, Spengler. Philippi^ had already some idea of this when he estahlished 

 his T. Gruneri. Reeve's figure, Sp. Ill, of T. ephippiiim, Spglr., exactly corresponds 

 with Spengler's original specimens and with T. Gruneri, therefore I fail to see the 

 reason why Römer finds that Hanley's figure of ephippiiim is "himmelweit ver- 

 schieden" from Reeve's figure; they are almost identical if the figures are placed 

 in the same position.

All the specimens from the Gulf of Siam are entirely destitute of the granu- 

 lated sculpture characteristic of galatæa (Hanley); at first I determined them as 

 belonging to a form near to T. Candida; but on account of the confusion which 

 has prevailed within this group (and which V. Beutin has but partially dispersed) 

 I asked Mr. Edg. Smith to be kind enough to compare them for me, and he deter- 

 mined them as M. Candida, Lam., "in which the peculiar granose epidermis is ob- 

 solete. T. arafiirensis, Smith, is dilTerent in form." Hanley (Proc. Zool. Soc. London, 

 XII, 1844, p. 147) has described, under the name of T. Diana, a form of his galatæa 

 with a smooth surface, and it must undoubtedly be this varietj' to which the 

 specimens from the Gulf of Siam are most closely allied.

- Gmelin's Tellina papyracea = Tellina {Metis) lacunosa, Ch. Spengler quotes: Lister, Hist. 

 Conch., pl. 395, fig. 242 as a synonym of his T. papyracea; this figure according to Mörch, resembles 

 more closely Spenglers T. sinuata.
