Ancey, Proc. mal. Soc, 1. c. : „Auriculella canalifera." — ,,Testa sinistrorsa, im- 

 perforata, ovato-conica, subtenuis, nitens, lineis incrementi obliquis laevibus obsoletisque 

 impressa, unicolor fulva, vel in medio ultimi anfractus zona fusca cingulata, aut etiam in- 

 tense fulvo-castanea zonaque albescente peripherica suturam supra concomitante circumdata. 

 Spira conica, sat producta, apice obtuso. Anfractus 614 planiusculi, sutura appressa, ultimus 

 dilatatus, rotundatus, abbreviatus, haud ascendens. Apertura obliqua, irregulariter ovata, infra 

 dilatata, emarginata, lamina parietali compressa, albida, mediocri, intus debiliore armata. 

 Columella appressa, leviter contorto-plicatula, plica albida, extus in spinulam erectam desi- 

 nente munita, oblique intuenti minute bisinuata. Peristoma tenue, vix nisi ad columellam 

 incrassatulum, leviter expansum, marginibus callo simplici nitidoque, haud tuberculifero 

 junctis." 



„Long. 6.75, lat. 3.6, alt. apert. (obhque) 2.5 mm." 



„Hab. — Halawa, Molokai (Baldwin)." 



„A very characteristic species, remarkable on account of the features of its columella, 

 and unlike any others in that respect. The shell has the texture of A. diaphana, but has 

 a more produced spire, different columella, and is imperforate."
