Extract

Anyone who has examined the so-called “protective” spines of the various Zoæa larvæ must have been struck by their great tendency to develop in one straight line, parallel to the long axis of the body. Among the Macrura this is the case in the Zooæ of Peneus, in the larva attributed by Claus to Hippolyte, and in the Galatheidé. In the Brachyura the same result is attained in a slightly different way.
