DOUBTFUL AND SPURIOUS SPECIES OF SUCCINEA. 



Succinea putris, LIN. (DESHAYES, Encycl. Meth., 21; DEKAY, 1839, 31; FERUS- 



SAC, Tabl. Syst, 9), and 



Succinea amphibia, DRAP. (FORBES, Brit. Ass., 1837, 144; FERUSSAC, Tabl. 

 Syst. ; BINNEY, Terr. Moll., II. 159 ; MRS. SHEPPARD, Tr. Lit. Hist. Soc. 

 Quebec, 1829, I. 194), have been quoted from America. Having never seen a 

 well-authenticated specimen of either, I omit them. 



Succinea vermeta, SAY, New Harm., Diss., II. 230 (1829) ; Dese. 23 (1840) ; 

 ed. BINNEY, 38 (S. venusta, W. G. B., err. typ.). Gould quotes this in the 

 synonymy of S. avara. See Terr. Moll., II. 64, 73, and above, p. 421. 

 Succinea aperta, LEA, Trans. Amer. Philo. Soc., VI. 101, PL XXIII. Fig. 101 ; 

 Obs., II. 107 (1839), is said by GOULD (Terr. Moll., II. 67) to be 

 identical with S. rotundata, of Sandwich Islands. 

 Succinea pellucida, LEA (Proc. Acad. Nat. Sci. Phila., 1864, 109 ; 

 Journ. of same ; Obs., XL 134, PL XXIV. Fig. 106), appears to 

 me to be Limncca columella. A figure of an authentic specimen, 

 received from Mr. Lea, is here given. 

 Succinea oblonga and putris, credited to North America by PREST- 



WICH, Quart. Journ. Geol. Soc., XXVII. 493. 



Succinca Haleana, LEA. Shell obliquely ovate, shining, somewhat transparent, 

 thin, golden color ; spire short ; sutures impressed ; whorls 3, con- 

 vex ; aperture large, broadly oval ; outer lip regularly expanded ; 

 columella incurved. Diameter, .17 mill. ; length, .23 inch. Alexan- 

 dria, Louisiana. (Lea.)

 XXIV. Fig. 110. 



Mr. Lea's original description is here given. Fig. 309 is drawn from a speci- 

 men received from him. See, also, L. &. Fr.-W. Sh., I. 259, 1869. 

 Succinea Moorcsiana, LEA. Shell obliquely oval, minutely striate, opaque, whit- 

 ish, somewhat thin ; spire exserted ; sutures impressed ; whorls 3, a little 

 convex ; aperture nearly round ; outer lip expanded ; columella incurved and
