The species inhabits the Andamans and Nicobars, Atjeh, New Guinea, New Hebrides, 

 Fiji Islands, Ponapé (Samoah) and Tahiti. About its habits nothing is known.

Heller's figure is taken from a young indrvidual, but my specimens attain a larger 

 size than that denoted by Alcock, the breadth of the carapace of an adult tf being 34 mm., 

 the length 29 mm. The carapace is broader than loqg, flattened transversely, and also in the 

 posterior two-thirds of the longitudinal line, but the anterior part is regularly and strongly 

 curved, so that the front is much deflexed and even curved backward. The whole surface is 

 very minutely punctate and the regions are scarcely defined, the furrows being represented by 

 very faint wrinkles ; the cervical groove is only distinct in its lateral parts and situated at 

 three-fifths of the total length of the carapace; the cardiac region is small and very ill-defined, 

 the intestinal area presents a lateral depression at either side; the branchial regions are per- 

 pendicularly declivous in their outer posterior angle, and usually exhibit here some faint 

 granules, but in the specimen figured these granules are very large, arranged in obscure and 

 oblique lines and very shortly hirsute; similar, but rounded and pearly granules, are found in 

 this specimen along the whole lateral margins and behind the supra-orbital border and in some 

 parts render these lateral margins rugose. The gastro-hepatic grooves are more or less distinct, 

 but usually their course is only indicated by two obliquely-longitudinal pits, from each of 

 which a very faint groove runs forward towards the notch between the external orbital angle 

 and the anterior epibranchial tooth, where again a pit is found; a third pair of depressions is 

 found on the mesogastric area, before the cervical groove. 



In dorsal view the anterior margin of the front is very faintly concave and entire, the 

 lateral angles are somewhat prominent and not rectangular, passing into the concave side margins. 

 Though there is on the surface of the front a faint indication of two flattened postfrontal lobes, 

 the front passes mostly imperceptibly into the epigastric area, but in the specimen figured the 

 postfrontal lobes are more distinctly marked and their anterior margin is formed by a trans- 

 verse crest. The orbits are very small, not even half as broad as the front, and the eye-stalks 

 not even reach the little prominent, subrectangular external orbital angle, the lateral margins 

 of which are much divermno- backward. A second and even a third lateral tooth 

 are always present, but they are obtuse, not acuminate anteriorly, turned upward ; the 

 second tooth is as long as the preceding, the third is usually shorter, but it may be fused 

 with some short, oblique or longitudinal verrucosities, immediately behind the tooth, at which 

 place the lateral margins of the carapace completely disappear, as in Cardisoma ; in dorsal 

 view the postero-lateral outlines of the carapace are subparallel, so that the greatest breadth 

 of the latter is found immediately behind the last antero-lateral teeth. The hind margin is 

 1Y2 times as broad as the front and accompanied by a fine furrow, that is continued on either 

 side and can be traced forward as far as the bases of the second pair of walking legs, where
