In thus identifying the Challenger shell referred to above, I only mean that it agrees with shells 

 thus named in the British Museum. Weinkauff, though he excludes for his species some of the 

 authorities quoted above, would probably class it uuder his Cyprcea, subtcres. I have seen no speci- 

 mens of that sjjecies, but neither the figure nor the description, nor the remarks on the description (see 

 Conch. Cab., ed. Kiister, p. 27, pi. viii. fig. 4, pi. xiii. figs. 1—4) give the impression that the species is 

 well defined. If, however, there really be two species, which Deshayes (Lam., Anim. s. vert., ed. 2, 

 vol. x. p. 555, No. 81, Cyprcea tabescens, Dillwyn) and Gray (Zool. Journ., vol. i. p. 381, No. 44 do.) 

 and Sowerby (Conch. 111., fig. 14 ?) have confounded together, then perhaps Weinkauff has done the 

 best thing possible in cutting the knot, and giving a new name to the second, retaining Gmelin's name 

 for the species which Schrbter (Einleitung, vol. i. p. 161, pi. i. fig. 7) had figured and described ; only- 

 it would have been better, if possible, had the existing names of teres and tabescens been disentangled 

 and fitted to their respective species without the introduction of this aggressive third name.
