Fulton (1896) original descriptions on Amphidromus adamsi articulata - “Like subunicolor, but with a reticulated colour-band composed of square dark brown spots encircling the periphery and continued at the suture of upper whorls; ground-colour may be either yellow or reddish brown.”
Fulton (1896) original descriptions on Amphidromus adamsi aureocincta - “Upper whorls dirty white, lower of a yellowish fawn colour; a narrow golden-yellow band just below and encircling the suture; lip and columella white. Long. 29-41 millim., maj. diam. 14-18 millim.”
Fulton (1896) original descriptions on Amphidromus adamsi duplocincta - “Ground-colour either yellow or reddish brown, with two purple-brown bands on last whorl, one above the pink umbilical area and the other at the periphery; lip and columella pink.”
Fulton (1896) original descriptions on Amphidromus adamsi inornata - “Thin, pale lemon-colour, first three whorls semitransparent, and with some oblique and more or less indistinct brown stripes, subangulate at the periphery; suture slightly channelled; lip and columella white; umbilical area sometimes tinged with pink.”
Fulton (1896) original descriptions on Amphidromus adamsi luteofasciata - “Ground-colour either bluish grey or white; last whorl encircled by three yellow bands situated above and below the periphery and just below the suture; the two upper bands are continued on upper whorls; sometimes there are some distant white spots or oblique white stripes at the periphery; lip, columella, and umbilical area pink.”
Martens (1903) original descriptions on Amphidromus adamsi obliquatus - “Testa elongate conoidea, sat tenuis, levissime striatula, nitida, carnea vell pallide flavida-virescens, guttis nigricantibus diaphanis raris adspersa, strigis albis latiusculis oblique deorsum et antrorsum descendentibus picta; apertura valde obliqua, peristomate crassiusculo, breviter reflexo, rosaceo-albido, extus et intus distinctius roseo-limbato, margine columellari verticali incrassato, umbilicum prorsus claudente, callo parietis aperturalis pertenui. Long. 38-40½, diam. 19-20, apert. alt. obliqua 18-19, diam. 11-13 mm.”
Fulton (1896) original descriptions on Amphidromus adamsi ornata - “Ground-colour either yellow or reddish brown, with a broad spiral band of short, oblique, equidistant dark brown stripes at the periphery, continued above at the suture; lip, columella, and umbilical area pink.”
Fulton (1896) original descriptions on Amphidromus adamsi rubiginosa - “Last whorl rusty brown, fading to dirty white on upper whorls; lower half of last whorl is darker than the upper part, the difference being more or less sharply defined; sometimes ornamented with oblique brown-coloured stripes and a reddish-brown fillet at the suture; lip and columella white at umbilical area is a narrow zone of brown. colour extending over the columella at point of insertion.”
Fulton (1896) original descriptions on Amphidromus adamsi rufocincta - “Ground-colour fawn or light brown, with three pink spiral bands - one immediately below the suture, and the other two above and below the periphery, the upper one being continued above."
Fulton (1896) original descriptions on Amphidromus adamsi simplex - “Ground-colour lemon, which is sometimes suffused with orange; a pink spiral band below the suture; upper whorls either plain or with some brown spots above the suture of third and fourth whorls. Long. 26 millim., maj. diam. 15.”
Fulton (1896) original descriptions on Amphidromus adamsi superba - “A most beautiful variety of a bluish-grey ground-colour, ornamented with three spiral colour-bands - a pink one just below the suture, one either yellow or pink at the centre of the whorls, and the third (a yellow one) at the lower part of last whorl; on the upper whorls are oblique stripes, which are interrupted by the spiral bands; lip, columella, and umbilical area pink.”
Fulton (1896) original descriptions on Amphidromus placidus - “Shell sinistral, broadly conical, slightly perforate, thin, obliquely striate, somewhat angulate at the periphery; whorls 6, slightly convex, apex brown; apical whorls white, lower of a pale lemon-colour; columella straight, rather thin, slightly expanded, white at upper part; lip pale purple brown, expanded and slightly reflected. Shell height – 31 mm, shell width – 16 mm.”
