A NEW LAND SHELL FROM SUMATRA.i 



BY T. II. ALDRICH. 



Nanina (Ariophanta) Dohertyi n. sp. PI. I, fig. 1, 2. 



Shell thin, waxy pellucid, light green, corneous, subimperforate, 

 Avhorls six, suture slightly margined, impressed, bordered below with 

 a narrow white line, body whorl acutely carinated and ridged, pro- 

 duced at aperture into a flattened spade-like terminal ; spire high. 

 Aperture subtriangular, lip reflected strongly, almost completely 

 covering the umbilicus. 



Locality, INIarang, on Southwest coast of Sumatra. 



Note. This shell is doubtfully placed in Ariophanta. It 

 resembles Nanina nasuta Metcalfe described from Borneo but is 

 much higher, lacks the band of that species, and is differently 

 produced. Received from Wm. Doherty, Esq. who states that when 

 alive it is green with a singularly delicate epidermis, and is arboreal 

 in its habit. Its color makes it almost invisible. Six specimens 

 received.
