Succiiica virgata microspira C. and F. (1878). 



S. V. pucblcnsis C. and F. (1878), not S. pucblcnsis C. and F.

Eleven specimens; from the banks of La Laja (H, vii, a), 



and from wet place with water oozing out over rocks, on the 



shore of Laguna de Catemaco (H, vii, d). Examples measure:

The Latin description of Crosse and Fischer (1878) gives 

 the name of this variety as var. (beta) microspira (p. 659), 

 but the French description gives it as var. (beta) pncblensls ; 

 under the remarks it is again called var. (beta) microspira. 

 The plate does not use the varietal name (xxvii-3). Von Mar- 

 tens (1900) re-describes the form as microspira n. 



Succinca brcvis Dunker? One specimen; from grass on 

 the cleared portion of the Hacienda de Cuatotolapam (H, ii, c). 

 This shell has quite the shape of a young S. virgata, but is 

 solider and more opaque than are even the adults of that spe- 

 cies. The growth-lines are heavy, so as to give the shell almost 

 a ribbed appearance, while the spiral lines are also quite evident. 

 The color (after stay in alcohol) is creamy and opaque, alter- 

 nating in stripes w^ith a rather dark amber. The shell has 

 almost 3 whorls, and there is a rather definite callus on the 

 columellar margin of the aperture.

 Sfrcptostyla irrigua similis Strebel. Five specimens; from 

 the ground in the lowland forests (H, i, a). The following is 

 the synonymy of the entire species, as it appears to me:
