Fishery Bulletin, 1985, Vol. 83 (Classic Reprint)
Excerpt from Fishery Bulletin, 1985, Vol. 83 The extensive collections (515 lots containing specimens) of S icyonia available from Mon terey Bay, Calif, to off Pisco, Peru, and the Opportunity to examine all except two of the extant type-specimens of the species have made a critical study of the genus in the eastern Pacific possible. The present work includes a definition of the genus and a key to the species occurring in the region. A complete synonymy and usually complete list of references, vernacular names, and a diagnosis precede the detailed description of each species, which includes a discussion of the extensive varia tion exhibited as well as meristic and morphomet ric data. In addition, relation of the length of the rostrum to the length of the carapace is graphed for 10 species. Color notes, size range at which males reach adulthood, and minimum size at which females have been observed to be im pregnated are given. Geographic and bathymetric ranges are delimited, and ecological data are pro vided. Analyses of the diagnostic features utilized in the recognition of species and a discussion of their phylogenetic relationships are also pre sented. Distributional maps as well as illustra tions of entire animals, genitalia, and a few other morphological features are included along with a bibliography which is as complete as possible. A statement of their economic importance follows the treatment of the pertinent species, and a list of the specimens examined, with their localities, is appended to each of the 12 species.
