PetaloconchuS, PiDonia, and Aletes, formerly regarded as di- 
stinct genera, are only Stages of growth occurring in the same 
species at different periods of its life. The names may he re-

cerning the syiiotiyniy of specieS.

CryptoUa (Ileshayes). This genus has been alluded to by Spengler in 
1781, and named Serpnla nwdreponna b}’- Modcer in 1794. It was again 
observed by Macdonald (Nat. Hist. Review, 1862, p. 78), who always found 
a sort of Sipuncidns in it; Dr. Gray (Proc. Zool. Soc. 1849, p. 74) a Pagurus. 
It is probable that the animal belongs to the Vermeiidce, but is often de- 
stroyed and replaced by those intruders. Morch, Journ. Conch, xiii. pp. 11-13.
