48 Original Descriptions of Achatinella. 



"Dr. Newcomb has followed in restoring A. livida, making it 

 include, beside Swainson's type, A. emersonii Newc, A.glauca 

 Nob., and A. reevei Ad. If A. emersonii and glauca are to be 

 merged m A. livida , would not a consistent system of classification 

 require that A. recta and undulata should likewise be placed under 

 ./. curta, since the relation is similar? " 



VULPINA GROUP. 

 55. Achatinella vulpina Ferussac. 



./. vulpina F£r. Prodrome : I, bunions, p. 60, No. 429 



Shell accuminately oblong, sinistral, sometimes rather ventri- 

 cose, whorls somewhat flatly convex, columella short, callous, 

 dentately plicate, lip of the aperture but little thickened; olive or 

 whitish, with oblique light red-brown streaks, variously painted 

 with spiral black or green or brown bands and lines, columella 

 purple-rose. — Rve. Conch. Icon. Achat. London, 1850; sp. 29. 



The colouring of this species is extremely variable ; there is, 

 however, but one prevailing idea in its manner of distribution. 

 The columella is of a livid purple-rose in all the varieties. — Reeve. 



This is one of the most common shells met with on Oahu, and 

 passes through numerous slight variations, which have led to their 

 description as distinct species. Mr. Gulick, who has very minutely 

 studied cabinet specimens, places the A. producta Reeve, as a syno- 

 nym of this species, and claims that in that gentleman's Mono- 

 graph he gives A. varia Gul. erroneously as the true vulpina. 

 Specimens exist in the French collection which passed under the 

 eye of Ferussac, and are labelled "A. vulpina" which answer to 

 the shells as figured by Reeve. No doubt can exist of the correct 

 references by European authors to this species. The dextral 

 vulpina differs greatly from the shell described by Mr. Reeve as 

 producta. The figure in Ferussac is from one of those unfortunate 

 individuals discolored by the hot bath. — Newc. 



Hab. Palolo to Manoa.
