The mesogloeal sphincter is, in comparison with the size of the specimens, not .strong, especially on the higher side: that is to say, there is usually a little difference in the development (if the spliinrter in the hjwer and higher sides of the contracted animal.

Its alioral end, furniing only a thin muscle- lamella, is situatrd nearer the endoilerm than the ectoderm, but
