Doubtful and Spurious Species of Succinea. 



Succinea putris, Lin. (Deshayes, Encycl. Meth., 21; DeKay, 1839, 31; F^-eus- 

 SAC, Tabl. Syst., 9), and 



Succinea amphibia, Dkap. (Foiibes, Brit. Ass., 1837, 144 ; Fi^.russac, Tabl. 

 Syst. ; Binney, Terr. Moll., II. 159 ; Mus. Siieitard, 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 vervieta. Say, New Harm., Diss., II. 230 (1829); Desc. 23 (1840); 

 ed. Binney, 38 (5. venusta, W. G. B., err. typ.). Gould quotes this in the 

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



Succinea aperta, Lea, Trans. Amer. Philo. Soc, VI. 101, PI. 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 pcUucida, Lea (Proc. Acad. Nat. Sci. Phila., 1864, 109 ; 

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

 me to be Limncea 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. 



Succinea 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 incm-ved. Diameter, .17 mill. ; length, .23 inch. Alexan-

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 Mo&i'esiana, 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
