One specimen of this species occurred in a collection of 
land-shells sent to me by Mr. John Whitehead from the 
island of Palawan. 
Lagocheilus similis, var., Edgar Smith. (Fig. 2, a, 0.) 
Among the shells collected by Mr. John Whitehead in 
Palawan and sent to me there are three specimens of what I

take to be the above species, only much better grown. When 
in perfect preservation it is covered with a brown epidermis 
having well-displayed transverse, regular, fine liration and 
the periphery adorned with a strong hairy fringe. 
The largest specimen measures :—-major diam. 18°75, minor 
15:0, alt. axis 7°5 mm. 
Cassidula bicolor, sp.n. (Fig. 3, a, 0.) 
Palawan. Collected by Mr. John Whitehead. 
This is a smaller shell than su/culosa, Mouss., to which it 
is nearest as regards the form of the aperture, but it is not so 
strongly formed. The body-whorl is crossed by shallow 
Nat. size.

longitudinal plications. The colour is a very dark sepia- 
brown, with two broad, parallel, very white bands, which 
extend to the outer margin of the peristome. I could find 
nothing like it in the British Museum collection.
