Scale bar applies to both a and b. female calyces were growing on different stolons; I never observed male and female calyces growing on the same stolon. Calyces of Barentsia benedeni contained either ovaries or testes. never both. Each of the 21 slide-grown colonies from Lake Merritt consisted of calyces of a single sex, although colonies did not contain very many sexually mature calyces (Fig. 3d). There were considerably more female than male colonies, probably because I had oversampled a single large female colony when originally removing colony portions from the mussels to generate the slide-grown colonies. The colony at the California Academy of Sciences (#105010) was huge and over- whelmingly female, consisting of about 950 female and 85 immature calyces (no male calyces were present); this colony is represented by the leftmost bar in Figure 3d. Barentsia discrete Calyces of Barentsia discreta (both museum and slide- grown colonies) contained either testes or ovaries, never both. In June 1995, when the slide-grown colonies first became sexually mature, only male (and immature) caly- ces were present. In July 1995. a few female calyces were present together with numerous male calyces in the same colonies. In August 1995. 11 of the 21 slide-grown colo- nies contained both male and female calyces at the same time, while 10 contained only male calyces; no colonies consisted only of female calyces (Fig. 3d). Five colonies in the collection of the Allan Hancock Foundation (57D/ 1, 3, 7, 8, 10) from California. Mexico, Ecuador, and Peru also had male and female calyces arising from the same stolon within a colony. Barentsia aggregata Many calyces in t
