She laid 62 egg capsules over 7 days, with a mean ± SD of 151 ±9 fertilized ova per egg capsule (random subsample of five egg capsules). Upon dissec- tion, her ovary held an estimated 3521 oocytes. In both years, most females had oocytes remaining in the ovary, suggesting that these females did not exhaust their supply of gametes before dying. In 1997, the mean ± SD ovarian mass was ± g. Eight of the 12 females had oocytes in the ovary (mean ± SD number of oocytes per gram of ovary = ± ). The estimated number of oocytes in the ovary of each of these eight females ranged from 345 to (mean ± SD = 3838 ± 5631 oocytes). For 1998. the mean ± SD ovarian mass was ± Thirteen of the fourteen fe- males had oocytes in the ovary (mean ± SD = ± oocytes per gram of ovary). For these 13 females, the estimated total number of oocytes in the ovary ranged from 604 to 5455 (mean ± SD = 2386 ± 1502 oocytes). In both years, the ovarian oocytes showed a range of size and structure; our counts included two classes of oocytes. We found small oocytes (less than 1 mm in diameter) that were characterized by a veined texture due to follicle cells that sur- rounded the developing oocyte (8). The presence of these oo- cytes suggests that the females had indeed developed oogonia that had yet to undergo vitellogenesis (8). We also found larger, translucent, amber-colored oocytes (1-2 mm diameter) that re- sembled the fully mature amber-colored oocytes in the oviduct. This study demonstrates that individual L. pealei females are capable
