The studies on the genus Viana (1968) and Priotrochatella (1970) have already appeared. The genus Emoda is assumed to have originated in Oriente Province, probably from some form of tlie West Indian genus Alcadia. From there it spread westward across the island into Pinar del Rio Province. It Bull. Mus. Comp occurs in each of the six provinces, but is absent from the Isle of Pines. The specific and sub-specific taxa assigned to Emoda were investigated. Of the 27 taxa proposed, it is concluded that 16 are valid. In addition, one new species, Emoda caledoniensis, is described and the subgenus Ghjptemoda Clench & Aguayo 1950 is raised to generic rank. INTRODUCTION The family Helicinidae appears in two widely disjunct areas of distribution cen-tered in the Caribbean in the western hemi-sphere and in Southeast Asia and the Philippine Islands in the eastern hemi-sphere. The island of Cuba has an espe-cially rich helicinid fauna, possessing no fewer than four endemic genera with numerous species. In a previous study (1968), the present authors have mono-graphed the endemic genus Viana, and in 1970, their monograph on PriotwchateJki was published. In this work we take up two more such genera, Emoda and Ghjpte-moda. In this series of studies, we also plan to complete the examination of all Cuban helicinids and to investigate the Cuban spe-cies of the genera HeJicina sensu stricto, EutrochateUa, Alcadia, Lucidella, Cerato-discus, and Froserpina. Lea (1834b: 161) described the first Emoda as Ilelicimi pidcherrima and until the appearance of Wagner's work (1907-1908), most other new species were in-cluded in the genus Ilelicimi. The name .
