Allied to A. mitra, but more obviously radiately ribbed than any 

 of the varieties of that species, and differing in the yellowish interior, 

 with opaque white central tract. Tlie largest specimen before me 

 measures, length 28, breadth 23, alt. 14 mill. The species varies 

 considerably in degree of elevation. 

 A. (jARRETTii Pilsbry. PI. 33, fig.s. 96, 97, 98. 



Shell small, oval, conical, the apex acute, erect, slightly in front 

 of the middle ; slopes convex. Surface having numerous close radi- 

 ating riblets, of which a few (about seven) are generally larger. 

 Color dull blackish-brown, or gray with lines of dark. 



Inside white, the large central area either solid blackish-brown or 

 clouded ; border narrow, black or light, dotted dark brown. 



Length 13, breadth 10, alt. 5 mill. 



Length 11, breadth 9, alt o] mill. 



Viti Islands. 



A small species, collected by Garrett, and apparently distinct 

 from the described Australasian forms, as well as from the few 

 described from Polynesia. The figures represent a strongly sculpt- 

 ured specimen, but some specimens have the riblets more nearly 

 equal in size, and in some the color, both inside and out, is lighter. 

 It is a very solid little shell, somewhat similar to some forms of 

 A. cubensis. It is much more solid and differently sculptured than 

 A. mitella. 



The only species reported from the Viti Islands besides A. sacch- 

 arlna is a Patella nana Dkr., enumerated in the Mus. Godeffroy 

 Catal. V, p. 149, 1874; but I have|3een able to find no description 

 of it. It is again catalogued in the Catal. vi, Nachtriige zu Catal. 

 V, p. 91, 1877. 

 A. STRIATA Quoy & Gaimard. PL 19, figs. 37, 38 ; PI. 35, figs. 25-29. 



Shell orbicular, convex, very delicately striated, brown or black ; 

 inside sky-blue, the margin brown. Apex obtuse. 



A large species, nearly round ; the summit is anterior. Length 

 30, breadth 25, alt. 6 mill. {Q.)
