PRODUCTA GROUP. 



59. Achatinella producta Reeve. 



./. producta Reeve. Rve. Conch. Icon, .\chat.. London, 1850, sp. 13. 



Shell somewhat elongately conical, dextral, whorls convex, 

 slightly margined at the sutures, columella conspicuously callous- 

 toothed, apex rather small ; olive-green, apex, columella, and 

 interior of the aperture white. 



Mr. Gulick is quite correct in placing A. hybrida and venidata 

 as synonyms of this species. The artistic skill of the "late Consul- 

 General of France," as displayed upon these shells, proved quite 

 sufficient to deceive their describer, and lead to a wrong "diag- 

 nosis." — Newc. 



The animal is strongly granulated above ; when young, of a 

 ])ale flesh, when adult, of a slate color, with the tentacular sheaths 

 of a dark slate. — Newc. 



Hab. Mauoa to Xuuauu. — Bald. Tantalus. 



This is the first named of a group of very common shells found 

 from Manoa Valley to Nuuanu. These shells are very nearly 

 allied to the older A. vidpina Fer., and should perhaps more 

 properly be grouped with that species, which is usually found in 

 Palolo. The description of A. hybrida Newc. is not given, as it is 

 simply a manufactured variety from A. producta Reeve. 



60. Achatinella bilineata Reeve. 



A. bilineata Reeve. Rve. Conch. Icon, .\chat.. London. rSso, sp. 22. 



Shell oblong-conical, dextral, rather ventricose towards the 

 base, whorls rounded, columella dentately plicate ; bright yellow.
