REPORT ON THE BRACHYURA. 
125 
Xantho impressus (Lamarck). Indo-Pacific Region (Mauritius to New Caledonia). 
Xantho hirtipes, Milne Edwards. Red Sea. 
Xantho truncatus, cle Haan. Japan. In this species the front is somewhat 
prominent. 
Xantho arcuatus, Heller. Tahiti. The basal antennal joint is somewhat 
elongated and surpasses the infero-lateral frontal process. 
Xantho macgillivrayi, Miers. North-East Australia. 
Xantho crenatus, Milne Edwards. Peru. 
Xantho bidentatus, A. Milne Edwards. Sandwich Islands ; Philippines, Sam- 
boangan ; Samoan Islands (Coll. Brit. Mus.). In this species, only the 
two posterior teeth of the antero-lateral margins are distinctly developed, 
but the lobes are dentiform or tuberculiform. 
II. Carapace very transverse, with the two or three posterior lobes of the antero- 
lateral margins developed, the lobes rounded ( Liomera (pt.), A. Milne Edwards). 
This section includes such species of Liomera as differ from the typical Liomera lata, 
as figured by Dana (which is regarded by A. Milne Edwards as the young of Carpilodes 
cinctimanus ) in having a shorter basal antennal joint, wdiicli is not produced along the 
exterior margin of the infero-lateral frontal process, and in which the fingers of the 
chelipedes are acute and the ambulatory legs not spinuliferous. 
Xantho punctatus, Milne Edwards. Inclo-Pacific Region. 
Xantho maculatus (Haswell). Endeavour River, North-East Australia. 
Xantho granosimanus, A. Milne Edwards. New Caledonia ; Seychelles (Coll. 
Brit. Mus.). 
Xantho dispar, Dana (Rio Janeiro (?), Dana), which comes near the species of 
this section, is probably to be referred to Heterozius, A. Milne Edwards. 
III. Carapace usually less transverse with the front more prominent, the denticles of 
the antero-lateral margins of the carapace more numerous and irregular. 
Certain of the species of this section approach the genus Paraxanthus. 
Xantho occidentalis, A. Milne Edwards. Cape St. Vincent. 
Xantho denticulatus, White. West Indies; Vera Cruz; Brazil. 
Xantho stimpsonii, Smith = Xantho multidentatus, Lockington. California, 
Cape St. Lucas; Mazatlan. Panama, (Coll. Brit. Mus.). 
? Xantho nudipes, A. Milne Edwards. Indo-Pacific Region, (Seychelles and New 
Caledonia).
