same island. It differs in being more slender and without 

 costas. L. liicida is straw color, while L. Jenudseni is corneous 

 with a slight yellowish tinge. The species is not abundant. 

 It was found under ferns among the moist rotting leaves.

From an examination of the types I agree with Mr. Sykes' 

 synonomy of this species, as sandwicensis and obclavata are 

 no doubt forms of the same species. Specimens in the Bishop 

 Museum Collection which I have referred to this species are 

 slightly larger than typical forms of L. sandwicensis and ap- 

 proach the form of L. olclavata. The average length, of 

 specimens from back of Leilehua, is 7.8, diam. 3.25, altitude 

 of aperture 3.2 mm., they are corneous with a brownish tinge.
