Islands of Selayar^ Jampea^ and Kalao. 145 



Smaller than Macrochlamys indifferens^ Smith, from South 

 Celebes, but consisting of an additional whorl, and of a paler 

 colour. 



MacroMamys minuta^ Martens, from Selayar is a closelj 

 allied form. 



Kaliella indifferens, Bcettger.

Hah. Amboina and Saparua [Boettger) ; Java [in Brit. 

 Mus.^fide G. B. Sowerby) ; Kalao [Everett). 



The specimens from Java were obtained from Mr. Sowerby, 

 who doubtless received them with this locality and the above 

 name. They agree precisely with the examples from Kalao.

Ilah. South Celebes [Martens and Wallace) ; Saleyer 

 Island [Martens and Everett). 



This species is excessively variable not only in colour, as 

 pointed out by Martens, but also Avith regard to the texture 

 of tlie shell. Some of the specimens collected by Mr. Everett 

 are quite thin and transparent (var. tenuis, mihi, fig. 2 i), 

 and one could hardly believe that they belonged to the same 

 species as the strong solid shells found along with them on 

 the same island if there were no connecting-links or inter- 

 mediate forms to judge by. The series at hand, however, 

 seems to point to the conclusion that they really are nothing 

 more than a variety, which probably was found either at a 

 different elevation or living under somewhat different con- 

 ditions to the stouter forms. I could add several colour- 

 varieties to those already described, but without the aid of 

 coloured figures it is difficult to convey to others the differences 

 of the various shades of colour. 



Xesta selayarensis. (PI. X. fig. 3.) 



Testa perforata, depresse turbiiiata, albida, ad peripheriam et sutu- 

 ram saturate fusco zonata, supra medium anfractus ultimi pallida 

 fusco spiraliter lineata, infra lineis paucis concentricis interdum 

 ornata ; anfractus 6, convexiusculi, regulariter et lente crescentes 

 striis increment! obliquis tenuibus aliisque spiralibus tenuioribus 

 sculpti, ultimus in medio rotundatus vix descendens ; apertura
