An examination of both Pfeiffer 's and Gulick 's types leads 

 me to follow Newcomb and Sykes in considering Gulick 's 

 species as identical with L. glutinosa. 



This is one of the largest species of Leptachatina from 

 Oahu. Specimens from the Waianae Mts., back of Leilehua 

 are smaller, more glossy and slightly darker colored than 

 those from the other localities. 



The measurements of a few specimens from some of the 

 different localities are : 



Length 10.5, diam. 6.0, length of apert. 5.5 mm. Halemano. 



Length 10.8, diam. 5.6, length of apert. 5.2 mm. Leilehua.
