PARTULINA, MAUI. 53 



It is smaller, with less convex whorls, the last one shorter. So 

 far as we know it is always dextral. Perforation small, some- 

 times closed. In the typical form the bands, of a light brown 

 color, are more or less distinctly spotted with darker; and when 

 the bands spread to cover most of the surface, they are marked 

 with dark streaks. The last embryonic whorl has oblique 

 stripes as in related species, and the first neanic whorl is irregu- 

 larly clouded and streaked. The columellar fold is low and 

 oblique, white. Lip distinctly but narrowly thickened within, 

 white, outwardly a little expanded. 



Length 21, diam. 12, aperture 10 mm. ; 6J whorls. 



Length 20, diam. 11 mm. 



A. talpina Gul. has always been considered synonymous wit{i 

 gouldii. It is here figured (pi. 11, fig. 17) from a specimen 

 from Gulick. Although Gulick mentions only one band, his 

 figure and specimens show numerous lines also. The colu- 

 mellar fold is slightly stronger and less oblique than in typical 

 gouldii. The original account follows: 



' ' Achatinella talpina, shell dextral, slightly perforate, elongate 

 ovate-conic, rather thin, subcorneous, not shining, finely 

 striated, beneath the lens scarcely decussated; brown with a 

 whitish band encircling the base, covered with a thin, brown 

 ash, velvety epidermis. Apex somewhat obtuse, tessellated 

 with white and chestnut; spire regularly conical; suture simple, 

 moderately impressed, whorls nearly 7, convex, the last regu- 

 larly rounded, equal to 62 to 76 hundredths of the length. 

 Columella strongly plaited above. Aperture semi-orbicular, 

 brownish-white within; peristome thickened within, scarcely 

 reflected anteriorly, with columellar margin white and reflected 

 over the deep perforation; parietal margin wanting. Length 

 21.6, breadth 12, length of aperture 9 mm.; weight 5.5 grains. 



"Var. b. With apex corneous, without tessellations; very 

 rare. 



" Var. c. Ventricose; spire short, curvilinear. A small speci- 

 men has the following dimensions: length 17, breadth lOf, 

 length of aperture 7f mm., Weight 4.5 grains."
