Long, broad diapophyses are given off well up on the arch. On the sixth dorsal they extend backward and upward at an angle of 30° above the horizontal, but passing posteriorly in the series they gradually assume a more and more horizontal position. In the posterior members they also extend outward at right angles instead of backward as in the mid-dorsal region. These processes gradually lengthen from the front to the back, reaching their max- imum length on the ninth and tenth dorsals, posterior of which they decrease sUghtly in length and also in other proportions. Where they attach, these proc- esses are broail, narrowing slightly outward. Vertically both front and back they.
