4. On the Homology of the Neural Gland in the Tunicata with the Hypophysis Cerebri

In an ordinary simple Ascidian, where both the branchial and atrial apertures are at or near the anterior extremity of the body, the region lying between them—the interoscular area of Laeaze-Duthiers—is small in extent, and contains three important structures, the nerve ganglion, the neural gland, and the dorsal tubercle, lying close together. The ganglion in such a case is elongated dorsoyentrally, and gives off nerves at its two extremities, one set ventrally and anteriorly towards the branchial aperture, and the other set dorsally and posteriorly towards the atrial.
