30 Mr. Sylvanus Hanley on the 



the characters of Gray's ideal of T. palmulata (from a speci- 

 men in the British Museum). Blainville, who avowedly 

 derived his description from Adanson's plate, has ascribed to 

 his T. Stutchhuryi^ pallets which precisely suit those of 

 Adanson's figure, but says the valves are perceptibly less long 

 than broad, which does not agree with the more equal height 

 and breadth of the valve portrayed in Adanson's memoir. 

 It is possible that the valves and pallet in one case or the 

 other did not belong to the same species. It might save some 

 confusion, if the shell be really a recognizable one, to prefer 

 the earlier Lamarckian appellation of hipahnulata (Syst.) f. 



In the synonymy of the Sowerbyan palmulata appears the 

 name T. PMUppii, Fischer. This name was first applied by 

 Gray (Ann. & Mag. Nat. Hist. 1851) to Philippi's erroneous 

 ideal of T. navalis (En. Mol. Sic. vol. i. pi. i.) ; but no 

 description was attached to his correction. 



T. minima, also annexed as a synonym, was very briefly 

 described, in French only, by Blainville, in his often-men- 

 tioned monograph, as having a very long stalk to its pallet. 



T. senegalensis. — Blainville, who has given this name to 

 the Taret du S^n^gal of Adanson (Mem. Acad. Paris, 1759, 

 pi. ix., and Voy. S^ndgal, p. 263, pi. xix.), observes that the 

 pallet is truncated, not " bicorn^e." As these words did not 

 harmonize with the pronged pallet depicted in the ' Iconica,' 

 I was puzzled, but found on examination of the museum 

 types that the fault lay in the drawing, which, as Mr. E. 

 Smith declares, gives " but the feeblest notion of the pro- 

 cesses copied." Adanson's figures, indeed, are so roughly 

 executed that I hardly dare conjecture what they were de- 

 signed for {navalis ?, &c.). None of them, however, resemble 

 the equally indefinite species of the ' Iconica.' The difference 

 of outline in the valves of Adanson's three species is not very 

 marked. 



T. nucivora. — As the illustrator has stated that he had not 

 seen the pallet, it is a pity that he did not more precisely state 



* Mr. Edgar Smitli observes that " the only shells in the museum 

 lahelled T. palmulata were pencilled by Mr. Samuel Stutchbury (a 

 dealer) as coming from Sumatra." He could not find either valves or 

 pallets which would suit the figures in the * Iconica.' 



t I am a little reminded of Adanson's figures by the valve and first 

 joint of the pallet of T. {Xyl.) Dtmlopi of Wright (Trans. Linn. Soc. 

 vol. xxiv.), a shell mentioned in Sowerby's monograph.
