This genus, while closely related to Pcecilia, Mollienisia, and Lebistes, is distinguished from these genera by the absence of forward- projecting spines on the ventral portion of the segments in the first prolonged ray of the anal. This ray is club-shaped and without. 40 Fig. 17. Limia hollandi Henn. Distal end of anal of male. X —. No. 4640, Carnegie Museum. Boqueirao, Brazil. serrations. The third prolonged ray bears the usual dorsal serrations. In most of the species, but not in the present, there is an antrorse spine on the ventral surface near the extremity of the first prolonged ray. The anal of the male is shorter than the head; the ventrals are equal to the head in length and are lancolate in shape. A dermal hood or prepuce occurs near the extremity of the fin. This genus includes eight species, seven of which are from Cuba, Haiti, and Jamaica, and one from the mainland at La Guayra, Ven- ezuela. The present new species is from the basin of the Rio San Francisco and neighboring streams of Brazil.
