236 CALIFORNIA FISH AND CAME a series of embryos from 14.5 to 46.5 mm (0.6 to 1.8 inches) SL were cleared and stained in a solution of 5% KOH and 0.5 g (0.02 oz) of alizarin red S dye. The embryos were then examined for presence of scales, size of scales (number of circuli), and extent of the body covered by scales. In order to ascertain the morphological juxtaposition of the fins to the ovarian folds, paraffin sections were prepared. RESULTS Nature of the Ovary The gravid ovaries of Hypsurus caryiar\d Emb/otoca jacksoni were somewhat spindle-shaped, with the anterior end bifurcated into two tapering horns. Inter- nally, right and left ovaries are largely but not completely fused into a single organ. The paired condition is much more obvious early in gestation (Figure 2).

It was found that the ovaries of both species are divided into seven compart- ments by six thin, vascular ovigerous sheets (Figure 3). These multi-folded sheets are attached dorsally and are connected anteriorly producing two open- ended subdivided sacs. Presumably this condition of compartmentalization of the ovary is a vestige of the original paired lobes. The surface of the ovarian cavity is covered with tall cuboidal epithelium cells under which is a layer of connective tissue (Figure 4).
