 dish and with golden reflections, on the ventral surface of 

 the last whorl. Aperture ovoid, piriform, bluish within, the 

 right margin simple and sharp, columella feebly arcuate, 

 whitish; a thin bluish callous on the right margin. Length 

 65, diam. 26, aperture 27x13.5 mm. (Furtado).

Resembles somewhat A. colubrina Morel., but differs in 

 proportions and the vivacity of its coloring, and by the gran- 

 ulation. A. perfecta Morel, is larger and not so slender, 

 with a somewhat different color-pattern.
