62 LEPTACHATINA, GROUP N. 



callus which is not joined to the outer lip, and its large 

 umbilicus. 



N. Group of L. sculpta. 



79. L. LUCIDA Pease. PL 8, figs. 65, 66. 



"Shell elongate, thin, imperf orate, dextral, glossy, trans- 

 lucid, longitudinally costulate ; spire somewhat obtuse ; whorls 

 7, convex, marginate and scarcely crenulate at the suture; 

 suture subimpressed ; aperture almost vertical; columella 

 thin; columellar fold obsolete; lip thin; pale yellowish corn- 

 eous, sometimes reddish brown at the suture. Length 6.0, 

 diam. 2.0 mm." (Pse.) 



Kauai: Kealia (Baldwin); Kilohana, district of Lihue 

 (Cooke). 



Leptachatina lucida PEASE, P. Z. S., 1869, p. 650 (nom. 

 sol.) ; Journ. de ConchyL, 1870, p. 93. Achatinella (Lepta- 

 chatina) lucida PFR., Mon. Hel. Viv., viii, p. 249. 



A single shell, from the last locality, agrees very well with 

 Pease's description in the texture of the surface and color, it 

 has, however, 8 whorls and is slightly larger than Pease's 

 type, having the following measurements: length 6.2, diam. 

 2.3, length of aperture 2.0 mm. 



The species is related to L. knudseni, but is easily separated 

 by its costulate surface. 



80. L. STRIATA (Newcomb). 



"Shell acutely turrited, reddish horn color, minutely and 

 impressly striated transversely ; apex acute ; suture moderate ; 

 whorls six to eight, the last % of the whole length ; aperture 

 produced, subovate ; columella excavated, truncated, twisted 

 below into a fold. Length 5.0, diam. 2.0 mm." (Newc.)

Tornatellina striata NEWCOMB, Proc. California Acad. Sci., 

 ii, 1861, p. 93. Leptachatina striata SYKES, Fauna Haw., ii, 

 p. 370. 



I was unable to find a single specimen of this species in 

 Newcomb 's collection., now in the Museum at Cornell Uni- 

 versity. Probably the type was in the California Academy, 

 and is now destroyed.
