Note, however, that in these Cyclosal- pas this delicate strand arises from the ante- rior branch of the last body muscle while in Apsteinia punctata it arises from the poste- rior branch of this mus- cle. All the body mus- cles are interrupted ventrally. The inter- mediate muscle is pres- ent on each side as a broad band, much longer on one side than the other. The oral and atrial muscles are shown in figures 54 and 55, the latter copied from StreifL Observe the asymmetry in the intermediate muscle of the two sides, and the greater length of the oral retractor muscle on one side. The gut is a compact "nucleus" (fig. 53). The eyes (figs. 56 and 57) have been de- scribed by Metcalf and Johnson (1905). They show definite depar- ture from even the most modified Cyclosalpa Fig. 54.—Apsteinia punctata, aggregated zooid from the left .
