AMPULLARIA. All 
the first half of the last being sculptured as in arata, the second half of the last as in 
exsculpta. These two so-called varieties seem to be individual variations of exaggerated, 
sculpture rather than local forms. 
Var. chiapasensis. 
Ampullaria malleata, var. y. chiapasensis, Fisch. & Crosse, loc. cit. p. 235, t. 48. fig. 5“. 
SmaJl, with more pointed conical spire and moderately large umbilicus. 
Long. 55, diam. 43 ; apert. long. 37, diam. 24 millim. 
Hab. S.K. Mexico: Las Playas, State of Chiapas, in marshes (Morelet }8). 
This form has a somewhat different appearance from the typical A. flagellata, and I 
should not treat it as a variety of that species if Fischer and Crosse had not done so. 
Var. oajacensis. 
Ampullaria malleata, var. £ oajacensis, Fisch. & Crosse, loc. cit. p. 235, t. 46. figg. 38, 3a, 5” 
Small, narrowly umbilicated and rather sharply pointed, with numerous inconspicuous pale bands; peristome 
orange. 
Long. 47, diam. 36; apert. long. 31, diam. 22 millim. 
Hab. 8. Centra Mexico: Monte de Mistam near Coapam, State of Oaxaca (Sallé 1°). 
Very near the preceding, save the longer spire; it is also somewhat like the 
specimens of A. flagellata from Cordova. 
The shell figured by Philippi (Joc. cit. p. 36, t. 9. fig. 7) under the name A. flagellata, 
Say, found by Liebmann in Mexico, without nearer indication of locality, comes very 
near this variety, only it is a little more globose and its peristome white, whereas it is 
orange-yellow in Fischer and Crosse’s figure. 
Var, melanostoma. (Tab. XXII. fig. 7.) 
Ampullaria reflexa, var. melanostoma (Parr.), Philippi, loc. cit. pp. 35, 58, t. 18. fig. 4 (1851) * 
Ampullaria livescens, Reeve, Conch. Icon. x., Ampullaria, t. 5. fig. 21 (1856) * 
Ampullaria flagellata, var. 1, Strebel, loc. cit. p. 27, t. 3a. fig. 142” 
Shining, greenish-yellow, with very short blunt spire, and the aperture rather dark inside. 
a. Long. 40, diam. 36; apert. long. 28, diam. 19 millim, 
b. 99 42, 29 37 5 39 32, 29 21 9 
Cc. 29 39, 29 37; 29 30, 99 20 99 
a. Dimensions of a specimen from Amatlan; 6. From Philippi’s figure; c. Specimen from Papantla. 
Hab. E. Mexico: Papantla and in a freshwater lagoon between Amatlan and Cosama- 
loapan (Deppe, in Mus. Berol.); Vera Cruz (Strebel). 
Var. malleata. (Tab. XXII. fig. 10.)

Very large, oval, with numerous malleated impressions, giving the shell a reticulated appearance ; interior of
