35. A. Hosei, Smith, Proc. Zool. Soc. 1895, p. 115, pi. iii. 



fig. 20. 



Log. Meri, Sarawak. 



Near flavus in form, with a thin yellowish-green epidermis 

 as in sylheticus, but easily distinguished from both by the 

 single colour-band encircling the last whorl. 



36. A. flavus, Pfeiffer, Proc. Zool. Soc. 1861, p. 194; Novit. 



Conch, no. 270, pi. xlvi. figs. 7, 8. 



Loc. Siam. 



Specimens of Adamsi, var. inornata, are often seen in 

 collections under this name ; but flavus is a more solid shell, 

 with a faint reddish band at lower part of last whorl. The 

 type specimens are all I have seen of this species. 



A. flavus, var. proxima, Fulton. (PL VI. fig. 4.) 



Loc. ? 



Differs from flavus in being more elongate, has two in- 

 distinct bands at basal part of last whorl, and has a spiral 

 line of equidistant light brown spots just below suture of 

 third and fourth whorls. 



A single specimen in my own collection. 



37. A. zebrinus, Pfeiffer, Proc. Zool. Soc. 1861, p. 194; 

 Novit. Conch, pi. xlvii. figs. 9, 10. 



Loc. Siam. 



Of this distinct and pretty little species I have only seen 

 the type specimen in the British Museum. 



38. A. areolatus, Pfeiffer, Proc. Zool. Soc. 1861, p. 194; 

 Novit. Conch, no. 272, pi. xlvi. figs. 11, 12. 



Loc. Siam. 



A thin shell somewhat like porcellanus, but with close 

 forked markings on the upper whorls. 



The type specimens are all I have seen.
