Hnh. South Floves. 



Vaiable both in form and colour. It may be only a 

 variety of X. cochlostyloides of Schepman, differing in its 

 greater size, more glossy surface, and the want of the 

 diaphanous periostracum. 



Xesta melanoraphe. 



Testa turbiuata, perforata, albida, circa medium anfr. ultimi et ad 

 suturam nigro cincta, supra medium auf. ult. zona fusca nigro 

 punctata, altera latiore infra ornata, strigis et maculis obliquis 

 albis hie illic interdum variegata ; spira conoidea, leviter con- 

 vexa : anfractus 6, convexiusculi, lente accrescentes, lineis incre- 

 menti tenuibus obliquis, striisque spiralibus minutis indistinctis 

 sculpti, ultimus subdesceudeus ; apertura leviter obliqua, late 

 lunata, intus albo et fusco zonata ; perist. tenue, margine colu- 

 mellari ad insertionem breviter dilatato et reflexo.

Hah. South Flores, low country. 



This species, judging from the specimens examined, is 

 more constant in its coloration than those previously described. 

 Probably in very fresh examples the opaque white epidermal 

 stripes which usually appear in the direction of the lines of 

 growth and only upon the last whorl are more evident, for in 

 ordinary specimens, being easily deciduous, they are generally 

 worn off. The dark brown band below the middle of the 

 body-whorl occupies nearly the entire base, leaving only a 

 pale band between it and the peripheral black zone and a 

 small central whitish space around the narrow umbilicus. 

 The suture is bordered on both sides with black or brownish 

 black. 



Pupina Dohertyi.
