The genus Pyramidelloides (5.1.) in the West Indies is reviewed. Four species are recognized, of which two are new to science, P. glaber and P. multicostatus. A syntype of Aclis trilirata De Folin, 1873, is figured. Regarding shell-characters only, it is not very clear whether these four taxa belong to only one genus, or even to one family.
