348 FAUNA HAWAIIENSIS 



subgenus Laminella Pfeiffer. 



Laminella Pfr., Malak. Blatt. i. 1S54, p. 126. 



Pfeiffer's original group was very heterogeneous, as was that of Pease under 

 this name (P. Zool. Soc. London, 1869, p. 648); the latter author also proposing 

 Perdicella for a portion of the group. 1 would propose to select A. gravida F^r., the 

 old and well-known species, as the type.

(70) Amastra {Lamittel/a) citrina (Mighels MS.) Pfeiffer. 



Achatinella citrina Mighels, Pfeiffer, Mon. Helic. Viv. 11. (1848), p. 234; Reeve,

 [animal]. 

 Pease united (P. Zool. Soc. London, 1869, p. 652) this species with A. vemcsta. 

 Conchologically, they differ in the periostracum, shape of whorls, &c., while, from the 

 descriptions given by Newcomb, the animals are distinct in colouration. 

 Hab. Molokai, Kalae to Waikolu (Baldwin) ; Molokai (Perkins). 



(71) Amastra {Laminella) concinna Newcomb. 



Achatinella concinna Newcomb, P. Zool. Soc. London, 1853 ['8541 P- i57. 

 pi. XXIV. fig. 79. 



Newcomb's type was a bandless dextral shell. In the very fine series collected, 

 both dextral and sinistral forms occur ; black bands are either absent or present, and, 

 in the latter event, vary from one to even four in number. 



Hab. Lanai (Newcomb, &c.) ; Koele side of highest point, side of highest point 

 furthest from Koele, near Koele at 3000 feet (Perkins). 



(72) Amastra iyLaminelld) depicta Baldwin. 



Laminella depicta Baldwin, P. Ac. Philad. 1895, p. 228, pi. xi. figs. 2)Z — 5 [animal 



described]. 

 A very fine series, shewing a range of colour from pale yellow to rich orange, 

 tinged with crimson ; it is sometimes dextral, but sinistral forms predominate. 



Hab. Molokai, Kamalo (Baldwin); mountains, and above Pelekunu (Perkins).
