Cross section of first maxillary segment of 59-hour embryo, (avi) Amnion, (bl) Blood cells, (coel) Coelomic cavity, (dc) Provisional dorsal closure, (ect) Ectoderm, (eps) Epineural sinus, {mes) Median mesoderm. The intercalary coelomic cavities are first seen during blastokinesis lying between the antennary and mandibular mesoderm. They are very small and evanescent and soon disappear. Among the Pterygota they have been described in but few forms. The mandibular coelom is first in evidence at 56 hours as a pair of small cavities lying in the hollow of the mandibular rudiments.
