HAWAIIAN NBSOPUPAE. 303 



Alt. 2.25, diam. 1.3 mm.; subcylindric. 



In forest at the head of Kamalo there is a large, stout, cyl- 

 indric form with the laminae of the surface more crowded, 

 and generally having an interpalatal fold. Length 2.4, diam. 

 1.25 mm. This may be called form kamaloemis (pi. 29, fig. 9) . 



Kauai : This sub-species has been taken in several localities 

 and is probably well distributed over the whole of the moun- 

 tainous area of the island. It is also occasionally found in 

 some of the fossil deposits of the lowlands. The specimens 

 from this Island are fairly typical. They are slightly more 

 tightly coiled than the typical form and the outlines are a little 

 more convex. A typical example, from back of Lihue, meas- 

 ures: Length 2.3, diam. 1.1, apert. (diag.) 0.83 mm. A fossil 

 specimen from Limahuli is decidedly smaller, more conical in 

 outline and there are but 5 whorls. Length : 1.95, diam. 1.05, 

 apert. (diag.) 0.75 mm. 



Oahu : This sub-species is widely distributed over the Koolau 

 range but is not represented by a large series in any of the 

 lots. From the Waiana? Mts. only a very few examples seem 

 to have been taken. It is also found, though only in a few 

 isolated cases abundantly, in a number of the fossil deposits 

 from this island. Most of the specimens are considerably 

 smaller than the typical form from Molokai. PL 29, fig. 7 

 represents a fossil specimen from Kahuku coral bluff. 



Specimens taken from a few of the lots in the Bishop 

 Museum collection showed the following measurements. 



Length 2.02, diam. 1.1, apert. (Diag.) 0.79 mm. 5 whorls; 

 Manoa Palolo ridge (Cooke). 



Length 1.9, diam. 1.0, apert. (Diag.) 0.75 mm. 5 whorls; 

 Waimano (Gouveia). 



Length 1.95, diam. 1.1, apert. (Diag.) 0.8 mm. 5 whorls; 

 Waialaeiki ( Gouveia ) . 



Length 2.08, diam. 1.08, apert. (Diag.) 0.76 mm. 5% whorls; 

 Popouwela, Waianae Mts. (Cooke). 



Length 1.8, diam. 0.95, apert. (Diag.) 0.7 mm. 5 whorls; 

 Malaekahana, fossil (Cooke). 



Length 2.0, diam. 1.07, apert. (Diag.) 0.76 mm. 5 whorls;
