In this genus the length of the male intromittent organ is about one-third of the entire length. The ventrals are minute, thoracic, and barely reach to the base of the 40 Fig. 4. Heterandria formosa Agassiz. Distal end of intromittent organ. X —• No. 6846, I. U. M. Jacksonville, Florida. The third or first prolonged ray of the anal of the male has the distal portion club-shaped, without serrations or hooks, the fourth ray ends in an antrorse point, the fifth ray bears dorsally a series of retrorse hooks, the sixth and seventh rays unite terminally to form the dorsal margin of the fin. As restricted by Regan, (P. Z. S., 1913, p. 995) this genus includes the type, H. formosa Agassiz, ranging from the Carolinas to Florida, and H. jasciata (Meek) from southern Mexico. The males of the latter i ies have not been d escribed. 14. Heterandria hasemani Henn, sp. nov. (Plate XX, fig. i.) 4663, C. M., type, a female, probably immature, 20 mm. 4664 a-c, C.
