 1889, p. 57). 



Two forms of it were obtained by Mr. Everett, also in 

 Palawan, one in which the last whorl is much more acutely 

 keeled and more finely sculptured beneath than in the other. 

 Considerable variation in these respects occurs also in the 

 Bornean examples in the British Museum. The very acute 

 specimens from Palawan are very like H. cymatium of Benson 

 from Penang. Two specimens of the latter, marked in 

 Pfeiffer's handwriting from Pulo Zancavi, Malacca, appear 

 to me quite inseparable from the present species, but two 

 others from Penang, presented by Mr. De Burgh, although 

 very like the var. Schumacher iana,, appear to have an addi- 

 tional whorl and to be less rapidly coiled, so that the last is 

 narrower than in the Bornean shell. 



6. Helix {TIadra) Traillii^ Pfeiffer. 



The typical form of this species is more conical than the 

 specimens obtained at Palawan by Mr. Everett, and much 

 more coarsely striated. The transverse bands also are not 

 nearly so dark-coloured as in the specimens just received. 

 Most of the latter are covered with a thin bright yellowish 

 epidermis, with which the dark zones contrast strongly. 

 They vary considerably in the elevation of the spire, but 

 none are so depressed as H. monochroa or its variety lyala- 

 wanica. Occasionally the ground colour above is of a dark 

 reddish tint. The bands on the body-whorl are usually four 

 in number, namely a narrow one at the suture, a broader one 

 at the periphery, a still broader one below it, and a faint one 

 above it. The last is sometimes absent. 



7. Cochlostyla satyrus^ Broderip. 



The series sent home by Mr. Everett from Palawan con- 

 firms the opinion of Dohrn and Cooke that G. palawanensis, 

 Pfr., G. cinerosa, Pfr., C. Itbrosa, Pfr., and G. Graellsi of 

 Hidalgo are mere varieties. 



Mr. Everett also obtained this species at Banguey Island, 

 situated between Borneo and Palawan.
