110 THE NAUTILUS. 



as typical, pi. 4, fig. 9, fig. 8, left, has the last whorl closely 

 streaked with rood's brown, cinnamon and pale pinkish buff, 

 the former predominating, crossed by several darker, burnt 

 umber, spiral bands and lines. A band below the suture white. 

 This pattern fades on the penult whorl, leaving the upper part 

 of the spire and the apex white. In some specimens the streaks 

 are more or less diluted, pi. 4, fig. 7, to the point of disappear- 

 ing, forming transitions to the following. The second main 

 pattern, pi. 4, fig. 6, has a cartridge-buff ground, a sutural band 

 and the spire white; streaks faint or wanting, but there are two 

 dark bands, weakly interrupted, at periphery and on the base; 

 sometimes a third below the subsutural white band. This is 

 much the coloring of A. spaldingi, 



The columellar fold is rather thin and situated high. The 

 aperture shows the banding vividly within. Outer lip quite 

 thin.

 whorls.

A. spaldingi is quite distinct from the light form of meineckei 

 by its texture, dull surface, etc. A. thaanumi stands nearer to 

 lehuiensis and meineckei, the unstreaked pattern of the latter ap- 

 proaching it; yet at present thaanumi appears distinct by its 

 coloration and rather solid, smooth shell. 



Mr. Meinecke's account of the finding of these shells follows.
