The Mysis is developed withinthis skin bag. The Spiny Lobsters (the Palinnrida) are not only well-knownarticles of food, but are exceedingly interesting on account oftheir strange transformations during development—transformationsmuch greater than those of the ordinary lobsters. There is onespecies in the European seas, and its metamorphosis has been 462 TRANSFORMATIONS OF INSECTS. studied especially by Gerbe and Spence Bate. The young ofthe spiny lobster are remarkable on account of their great resem-blance to those of another genus, Phyllosoma. M. Gerbe has nodoubt of the identity of the young forms of these two genera, theadults of which are very different; but Spence Bate, after weighing. THE ZOiiA OF Palinuriis vulgaris (the SIINY lobster).(After M. Gerbe.) the evidence on both sides of the question, determines that thezoea are not identical. The great difference between the minia-ture and the perfect spiny lobster can be appreciated by com-paring the engraving of the Zoea with that of the adult form. The outside figures belong to species of the genus Praniza, andare small Isopoda, the variations in colour of which are very remark-
