A. teliao Newc. Am. Jour. Conch., iS66, ii, p. 214, pi. xiii, figs. 11, 12. 



Shell sinistral, acutel}^ conical, pointed at the summit, inflated 

 below; whorls 6, rounded; suture deep; aperture subovate; colu- 

 mella short and broadly plicate; color white, covered with a thin 

 epidermis, with black and brown undulations often so dense as to 

 cover most of the shell; a broad sutural carmine band is a constant 

 characfler; aperture within white; columella and adjoining portion 

 of the base of the shell pink or orange. Long. 15/20, lat. 9/20 poll. 



Remarks. There is a beautiful group of these finely painted 

 acuminate Achatinellae, commencing with A. veiuista Mighels, and 

 containing the following series: A.veinista Mighels, A.citrina 

 Mighels, A. ranyi Newc, A. sanguinea Newc, A. teh'ao Newc, 

 A. picfa Jklighels. The four central islands of the group are repre- 

 sented by these species, the first two from Molokai, sanguinea from 

 O^Vi, picta from Maui, the other two from Lahaina. — Newc. 



A fine, light colored variety, with a rosy tip, is occasionally 

 found, but is much less common than those with a dark epidermis 

 studded with small, white triangular markings. — Newc. 



Animal, above tessellated brown and white; mantle of a dusky 

 5'ellow; bottom of foot of same color; margined with white; ten- 

 tacles long and of light brown; motions timid. — Newc. (An. lyyc 

 New York, vi, p. 334.) 



Hab. Mountains and behind Koele. — Perkins. 



It may be noted that A . ferussaci Pfr. has been omitted from 

 this as.sociation as the typical shell in Mr. Cumings collecftion is a 

 worn, rather large sized sang^dnca.
