    This larva, known by the name of phyllosoma (Fig. 28), is very broad, thin, and leaf-like, and quite transparent, so that some of the larger kinds were formerly known as “ Glass Crabs.” The thin oval carapace does not cover the whole of the thoracic region, which is disc-shaped, with four pairs Fig. 28—The Phyllosoma Larva of the Common Spiny Lobster [Palimmis vulgaris—see Plate V.). Much enlarged. (After J. T. Cunningham.) of long slender legs, each with an exopodite. The abdomen is relatively small. The intermediate stages between the phyllosoma and the adult are still very imperfectly known. In tropical seas phyllosoma larvae of large size are found, sometimes reaching two or three inches in length. The larva of the Common Spiny Lobster {Palmurus vulgaris)^ however, does not exceed half an inch in length.
