More- over the proximal pore is so shallow that it disappears with the least abrasion and many of the zooecia appear deprived of it. We have not observed ovicells nor have we discovered the arrangement of the zooecia around the anccstrula and we are ignorant of the mode of formation of the two adjacent zoarial lamellae. For this a large num- ber of sections is necessary and our specimens are too few. The ancestrula is always placed at the base
