A few dead examples found in beach-sand. 



Since the publication of my paper on the Land-shells of Cook's 

 Islands Mr. E. L. Layard has sent me for determination a Ceylon 

 species of Laimodonta, which proves to be L. layardi, and is 

 identical with Pease's L. conica. Dr. Cox and Gassies record 

 L. layardi from New Caledonia, and Pease quotes it {conica) from 

 " Central Pacific." I have obtained it in all the groups from the 

 Paumotus to the Viti Isles. 



The species now under consideration is closely allied to the 

 Sandwich-Island L. bronni, but is smaller, more slender, and the 

 spiral engraved lines are more conspicuous. My examples average 

 from 6 to 8^ miilim. in length. Colour chestnut-brown, with one or 

 two whitish bands. The outer lip is slightly sinuous posteriorly 

 and has one or two internal riblets. All the three descriptions 

 alluded to mention a single plait in the palate. In the eight 

 specimens before me six have two riljlets in the palate. 



Station under stones above high-water mark.

Eiiijht examples found lurking under stones a little below high- 

 water mark at Laiithaia Island. 



Our specimens do not differ from the New-Caledonian shells except 

 in being paler. Its sub^lobose form, small, crowded granulated 

 spiral ridges, fulvous-brown colour, sli-jlitly shouldered body-whorl, 

 and short mucronated spire will readily distinguish it. The flattened 

 callose columella is armed with two compressed transverse folds.
