Camaena trailli bugsukensis, new subspecies. 



This, the smallest known race of Camaena trailli, comes from the island 

 of Bugsuk off southeastern Palawan. Three specimens donated to the 

 U. S. National Museum, Cat. No. 219,055, from this locality, yield the 

 following measurements: 



The present race is a brightly colored one. The upper surface of the 

 whorls has the usual brownish surface. All the three specimens before 

 me have a narrow dark brown band at the summit and another of the 

 same shade of about double the width, at the periphery, the latter being 

 flanked on each side by a light zone as wide or wider than the dark band. 

 Number one has a broad band paler than the peripheral, but almost as 

 wide, in the space between the peripheral band and that at the summit. 

 This is not quite median but a little nearer the periphery than the summit. 

 In number two this band is absent while in number three it is reduced 

 to a narrow line. All three have a dark basal band about three times 

 as wide as the peripheral and of the same shade as that. The pale space 

 between the peripheral dark band and the basal is a little wider than the 

 peripheral zone. The anterior half of the base is buff. The peristome 

 of the aperture is a little darker than the dark brown color bands. The 

 inner edge of the columella at its insertion is bluish. 



Mr. Weber states that these mollusks were found clinging to leaves 

 and on trunks of trees and that they hide in hollow trees and crevices 

 during dry weather. 



Cochlostyla palavanensis bancalanensis, new subspecies. 



Four shells collected by Mr. Weber at Bancalan Island are sufficiently 

 distinct from any of the known races of Cochlostyla palavanensis to merit 

 a trinomial designation. They have the apical whorls livid pink; in the 

 Cochlostyla palavanensis palavanensis they are usually white. The whorls 

 are uniformly more inflated with the aperture comparatively larger and 

 more flaring than in Cochlostyla palavanensis palavanensis. 



The narrow dark band at the suture in Cochlostyla palavanensis palava- 

 nensis is wanting here or only indicated by a line of small dark spots. 

 There are two color phases of this subspecies in the sending of which 

 Mr. Weber states: Col. 027, Cat. No. 219,046, U. S. N. M. "Found 

 crawling on trunks of trees and clinging to leaves of bushes from within
