GARTH Allan Hancock Foundation, University of Southern California John Garth, over more than a quarter of a century, has carefully studied the majid spider crabs of the 'New World'. His synthesis of the classifications of Balss and Alcock, based on traditional regard for characters such as orbit, rostrum and abdomen and, most of all, his attention to the challenge posed by features of the male first pleopod have provided the stimulus for our approach to this study.

Its collections, made from Takeda et al. (1969 et seq.). depths of 10 to 5,684m over the next 12 months, were returned The extensive studies by Mary J. Rathbun represent at to Amsterdam and over the next fifty years were the subject of least fifty per cent of the reports on the fauna of other areas. numerous extensive reports: decapod Crustacea figured Her studies on the crabs of the Philippines (1916), the western prominently amongst them. The spider crabs, however, were Indian Ocean (1911), Hawaii (1906), Siam (1910), eastern only briefly treated: Ihle & Ihle-Landenberg (1931), in a Australia (1918) and north western Australia (1914; 1924) are report outside the Siboga series, described a few new species basic to studies of any other local fauna.

Stephensen (1945) and The Indo-West Pacific spider crab fauna has been treated Garth (1958) have given considerable emphasis to the form of in several major reports since Herbst, Fabricius and Latreille the first pleopod of the male. Garth noted that divisions described the animals collected by early voyagers. The within subfamilies proposed by Balss on the basis of the inter­ Japanese fauna is undoubtedly the best known through com­ calated spine, were not congruent with divisions based on prehensive treatments by Sakai (1938; 1965a; 1976) following male first pleopod form. Garth (1958: 13) went on to say that the classic studies by De Haan (1833-50) and those of Miers he would make further application of the groupings based on (1879b), Parisi (1915), Balss (1924), Rathbun (1932) and male first pleopods were it not for (i) the fact that each sub- 2 family in the existing scheme contained species with pleopods listed in the Appendix. We thank the authorities of the which did not fit into major groupings and (ii) absence of museums concerned. knowledge of the 'Old World' (and presumably Indo-Pacific) species: a new system could lead to confusion were it based solely on the 'New World' fauna.
