P. DOLEI (Baldwin), p. 60, is rarely found dextral. 



P. CARNICOLOR Bald., p. 58, might better be classed as a sub- 

 species of eburnea. 



P. TEREBBA Newc., p. 61. According to Mr. Thaanum, tere- 

 bra-ligneria forms are all around the head of lao valley, high 

 up ; also on Mt. Helu and Mt. Lihau.

Achatinella saccata Pfr. is an absolute synonym of the 

 above. Through the kindness of Mr. E. A. Smith I can figure 

 the type-specimen in the British Museum. The original de- 

 scription follows. 



Achatinella saccata Pfeiffer. PI. 54, fig. 4. Shell subper- 

 forate, sinistral, turrited, rather solid, striatulate, a little de- 

 cussated under the lens, glossy, white (candida) ; spire regu- 

 larly tapering, the apex acute ; suture narrowly margined ; 

 whorls 6%, rather flattened, the last equal to two-fifths the 

 length, a little convex, the base subcompressed-sack-like ; colu- 

 mellar fold high, tooth-shaped, brown or flesh-colored; aper- 

 ture very oblique, semioval, the base laterally produced, inside 

 pale rosy ; peristome simple, unexpanded, the columellar mar- 

 gin dilated, somewhat free. Length 21, diam. 9y 2 mm. Sand- 

 wich Islands, Mus. Cuming (Pfr.). 



Achatinella saccata PFR., Proc. Zool. Soc. London, 1859, p. 

 30 ; Monographia Hel. Viv., vi, 175. Eburnella saccata Pfr., 

 PEASE, P. Z. S., 1869, p. 647. 



The slight roughness of the figure is due to the process of 

 reproduction.

The species are most numerous in northern Hawaii, but ex- 

 tend more than halfway down the island, on both sides. The 

 colonies, except in Hamakua district, are extremely rare and 

 isolated. Their locations on the island may be represented 

 thus.
