Color: Carapace a deep transparent blue throughout, chelipeds and pereiopods more transparent but of same blue color; entire megalopa peppered overall with numerous scattered red chromatophores, most prevalent as follows: on manus of cheliped forming a distinct red band; scattered dorsally on carpus of same, less so ventrally; walking legs banded with red anteriorly and posteriorly; additional scattered red chromatophores on epimera. and between walking legs 1 and 2 ventrally; on posterior margin of abdominal somites in interrupted line; dorsally on surface of telson in three large expanded groups; in addition, numerous white spidery or "snowflake" chromatophores on frontal region; eyes dark brown. For comparative purposes the data on zoeal and megalopal stages in other species of Pacliyclicles are still quite sketchy, and even where complete develop- ment is known many inconsistencies appear in the same species (see , Table I and Discussion below). However, a provisional synopsis of zoeal features using the known data that seem most reliable may be of aid in identifying at least some of the porcellanid larvae in the plankton to the genus Pachychelcs. SYNOPSIS OF LARVAL CHARACTERS IN THE GENUS PACHYCHELES Carapace Rostral spine elongate in both zoeal stages, generally straight, not upswept, heavily spinose overall or armed only laterally and ventrally in some; lower mar-.
