 an angle, nearly covering the perforation. Alt. 35, diam. 18.2 mill.

Amphidromus furcillatus Mouss., FULTON, Ann. Mag. N. H. (6), 

 xvii, p. 76. 



Mousson's original description, translated above, was from a speci- 

 men in rather poor condition, according to Fulton ; the ground-color 

 having faded. In fresh specimens the ground is buff, with a rather 

 wide pale zone below the suture (which has a yellow or sometimes 

 pink margin), and fading to whitish on the spire. This ground on 

 the last whorl is closely and more or less conspicuously streaked with 

 grass-green lines. The purple- brown oblique stripes or flames are 

 forked or broken into three branches above, with great regularity, 

 upon the pale belt below the sutural margin. When these flames 

 continue to the aperture, we have typical furcillatus, but when they 

 fade upon the last whorl, and the green streaks are conspicuous there, 

 it is the form virescens (figs. 38, 39). In the typical form the bases 

 of the purple-brown stripes may be more or less united by a spiral 

 band, and sometimes there is another defining a small dull reddish 

 columellar area. This area is to be seen also in the var. virescens. 

 Fig. 40 is a copy of the type figure. 



The coloration is strikingly like certain forms of A. quadrasi.
