New comb, Proc. Calif. Acad., L c. : „Achatniella Alexandri." — ,,Ach. testa per- 

 forata, sinistrorsa, elongato sub-cylindracea, nitida, rufo-brunnea, nigro-elongato-venulato- 

 inosculante picta; anfr. 6 convexis, regulariter accrescentibus; apice obtusiusculo ; sutura 

 modice impressa, non emarginata ; apertura parva, sub-ovata; labro acuto ; columella alba 

 breve, subrecta, truncata, infra in plicam tortam terminante." 



„Long. 0.6 polL, Diam. 0.25 polL, Apert. long. 0.2 poll., o.i lata." 



„Hab. Insula Sandwich. (Maui.)" 



„Remarks. — This species is more cylindrical than any of its congeners, resembling 

 most A. Renyi, Newc." — muß heißen A. Remyi, Newc, Annais Lyc. New-York, Vol. VI, 

 1855, pag. 146, Nro. 7, — „which is longer, not umbilicate, more pointed at the apex, 

 with a twisted, not truncate, columella." 



,,From venusta and citrina, Mighels, it varies both in form and color. With some 

 varieties of picta it Claims analogy only in the general plan of painting. Its striking cha- 

 racteristics are its blunt apex, slightly rounded whorls, small aperture, short and white co- 

 lumella, umbilicus, and general plan of coloring." 



„A few specimens were coUected at an elevation of 7500 feet, on West Maui, by 

 the Rev. M. Alexander, to whom the species is dedicated." 



Gehäuse durchbohrt, linksgewunden, länglich fast cylindrisch, glänzend, rötlichbraun, 

 mit länglichen, schwarzen, ineinander mündenden Adern gezeichnet; Umgänge 6, gewölbt, 

 regelmäßig aber langsam zunehmend; Apex ziemlich stumpf; Naht mäßig eingedrückt, nicht 

 ausgerandet ; Mündung klein, fast eiförmig, Mundsaum scharf ; Columella weiß, kurz, fast 

 gerade, abgestumpft, in eine nach innen gehende, gedrehte Falte endend. 



Länge 16 mm, Durchm. 8 mm. 



Der einzige Unterschied, der für mich zwischen Alexandri, Newc. und venusta, Migh. 

 besteht, ist der, daß Alexandri auf Maui lebt und venusta auf Molokai.
