Despite its regional focus, Haig’s (1960) monograph of eastern General morphology. – The general body shape is crab- Pacifi c species included 87 of the 225 species estimated to like and the carapace is well calcifi ed.

The eyes are pigmented; ocular orbits are sometimes of valid species from 225 to 277. well developed and ocular acicles are absent. The antennules have broad basal segments. The antennal peduncles are four-segmented, with the distal three moveable; antennal HISTORY OF CLASSIFICATION acicles are absent. The third maxillipeds each have a broad and fl attened ischium; no crista dentata is developed. Gills A. Milne-Edwards & Bouvier (1894) reviewed the early consist of 14 pairs of biserial phyllobranchiae, paired placements of the family and despite their superficial arthrobranchs are present on each third maxilliped and on resemblance to brachyuran crabs, the classifi cation of the pereopods 1–4; one pleurobranch is developed on body wall Porcellanidae has had a much less convoluted path than seen above each pereopod 2–5. for the lithodids and Lomis.

The pleon is well developed, symmetrical, carried bent under cephalothorax, and held against thorax. It is composed of six pleomeres and a telson.

Females usually 109 Osawa & McLaughlin: Checklist of world Porcellanidae have paired pleopods on each pleomere 3–5, but those of Aliaporcellana telestophila (Johnson, 1958) [Polyonyx] pleomere 3 are sometimes reduced or absent.

In all other porcellanids studied to date, Ancylocheles gravelei (Sankolli, 1963) [Porcellana] uropods develop in the megalopal stage.

Although previous data indicated that Enosteoides lobatus Osawa, 2009 the Porcellanidae was correctly placed in the Galatheoidea, Enosteoides melissa (Miyake, 1942) [Porcellana] Ahyong et al.
