Smaller, more tapering toward the ends and less cylindrical than 

 hitii. Long as is the above list of references, it could readily 

 be doubled ; but everything of value is believed to be here in- 

 cluded. 



A. SOLUTA Gmelin. PI. 42, fig. 18. 



Shell large, fragile, cylindrical, tapering toward the ends ; cov- 

 ered with a thin pale yellowish- brown epidermis. Spire projecting 

 but low and obtuse, terraced ; shoulder of whorls acutely keeled, a 

 flat, wide anal fasciole between keel and the deeply impressed suture. 

 Whorls nearly 5, the first one a minute, uptilted and half immersed 

 apical nucleus; body whorl forming most of the shell, densely 

 spirally striated throughout. Aperture narrow in its upper half, 

 with a wide posterior sinus extending back about a third of a 

 whorl ; lower half dilated and ovate, effuse at base. Outer lip fra- 

 gile, arching forward in the middle; coluinella very concave, with

The spire in this form projects more than in any of the other spe- 

 cies. It varies much in size, some Australian specimens being less 

 than half the dimensions given above. Fig. 16 of plate 42 repre- 

 sents the A. /'//"/> df Adam?, which Angas and Smith agree is a 

 synonym. A. Adams and Sowerby have given an incorrect syn- 

 onymy. The animal has been figured by Arthur Adams
