306 HAWAIIAN NESOPUPAE. 



Length 1.4, diam. 1.0, apert. (diag.) 0.65 mm. Whorls 4% 

 (topotype). 



Length 1.56, diam. 1.0, apert. (diag.) 0.63 mm. Whorls 4y 2 

 (topotype). 



Ancey's type specimen, according to my method, measures 

 1.53 mm. in length. 



This species has not yet been reported from Kauai. 



Oahu : widely distributed over the Koolau range ; up to this 

 time none have been seen from the Waianae Mts. Shells of 

 the different colonies differ but slightly from each other in 

 size and otherwise agree very closely. Most of the specimens 

 are slightly lighter colored than those from Hawaii. 



Length 1.51, diam. 1.0 apert. (diag.) 0.64 mm., 4% whorls; 

 Waialae-iki. 



Length 1.4, diam. 0.98, apert. (diag.) 0.61 mm., 4% whorls;. 

 Nuuanu. 



Length 1.53, diam. 1.02, apert. (diag.) 0.64 mm., 4% whorls;. 

 Kaliuwaa. 



Lanai : I have been able to examine but two specimens of this 

 species collected on Lanai. Both specimens agree closely with 

 the typical form. One of them measures: length 1.47, diam. 

 0.98, apert. (diag.) 0.65 mm., 4% whorls. 



Maui : This species is only known to have been taken from 

 three localities on West Maui, and one from E. Maui. Like the 

 specimens from the other islands, all the Maui specimens agree 

 closely with the typical form. A specimen from Honokahau 

 measures: length 1.43, diam. 1.02, apert. (diag.) 0.64 mm.,, 

 whorls.
