 with two faint series of pale brownish and very small spots ; the 

 last with a narrow yellow zone below the suture, circumscribed by an 

 indistinct, broad, white band, and furnished with two fine brown 

 revolving lines more or less evanescent towards the aperture, the 

 upper one at the periphery, the other around the yellow umbilical 

 area. Aperture oblique ; colurnella straight, thin, expanded, white. 

 Lip thin, white, slightly expanded. 



Length 23j, diam. 14, length of aperture 11 mill. 



Locality : Cochinchina. 



This, as well as the following, are members of the group of A. 

 flavus Pfeiffer, according to Mr. Hugh Fulton, who kindly ex- 

 amined the specimens and declared them to be new species. From 

 the former it differs in being shorter, in having 6 whorls only, a 

 dark colored apex, two narrow revolving bands on the last whorl, 

 and other particulars. Named in honor of Mr. Fulton, who has 

 very thoroughly and carefully monographed this difficult genus. 



Amphidromus Eudeli Anc. 



Shell sinistral, rather solid, oblong-conic, obliquely striate, nar- 

 rowly rimate ; spire conic, apex dark brown ; whorls 7, convex, the 

 first ones dull white, the fourth and lower ones cream, with oblique 

 bluish-gray stripes, interrupted at the middle on the penultimate 

 and preceding whorls, and evanescent at the suture ; last half 

 whorl bluish-gray, with a cream-yellow band and umbilical area of 

 the same tinge ; a narrow infra-sutural line of a reddish-brown color 

 on the last and penultimate whorls. Aperture small, oblique, ex- 

 panded, interior grayish. Columella thick, reflected, paler at the 

 upper part. Lip thickened, dark brown externally, purple inside, 

 particularly so near the umbilicus. 



Length 28, diam. 14, length of aperture 11 mill. 



Locality : near Binh-Dinh, Annam, in forests (E. Eudel). 



This is allied to A. zebrinus Pfeiffer, from Siam, but is appar- 

 ently larger and more solid, and differs in having a purple peristome ; 

 externally black-brown, and several striking characters.
