Phymodius obscurus (Lucas). 
Chlorodius obscurus Lucas, in Jacquinot and Lucas, Yoy. au Pole Sud, Zool., Ill, Crust., p. 26, 1853; 
atlas, pi. in, fig. 4, 1852 (?). . 
Phymodius monticulosus (Dana), Alcock, Jour. Asiat. Soc. Bengal, LX VII, 1898, 163, and synonymy. 
Hilo, Hawaii, H. W. Henshaw; south coast of Molokai, station 3834; Honolulu; Honolulu Reef; 
Oahu, Galathea Expedition, received from Copenhagen Museum ; Oahu, Dr. T. H. Streets. 
If this species is kept separate from P. ungulatus, the name given by Lucas should take precedence 
of that given by Dana, as the figure at least of the former antedates Dana’s work. (See Crust. U. S. 
Expl. Exped., I, 207.) 
Phymodius nitidus (Dana).

Pilodius nitidus Dana, Crust. U. S. Expl. Exped., I, 218, 1852; pi. xii, fig. 7, 1855. 
Honolulu; Waikiki Beach; south coast of Molokai, station 3834. 
Phymodius laysani, sp. nov. 
(PI. xn, fig. 8.) 
Regions of carapace well defined and subdivided by deep grooves, the lobules corresponding very 
nearly with those in P. sculptus (A. Milne Edwards)-. 1L is, however, separated from the first antero- 
lateral lobe, 2L and 3L are confluent, 1R is not cut off from the marginal lobe. Surface crisply granulate. { 
Outer angles of front not separable from the inner angles of the orbit. Orbital fissures very faint. 
Antero-lateral border cut into four lobes. 
Basal antennal joint touching the front by its inner distal angle, its outer angle prolonged into the 
gap between front and orbit. 
Chelipeds of male equal, short; some hairs on ischium, merus and carpus; arni granulous outside, 
sharply so above; wrist granulous- and nodulous, a blunt tooth inside; hands with granulated nodules 
above gradually diminishing below to large granules and then to fine granules; granules continued at 
least half length of fingers; the latter stout, with thick, blunt points, very slightly hollowed. 
Legs finely granulous, sharply so on upper margins, which are thickly fringed with long yellow 
bristles. 
Dimensions. — Male type, length 5.8, width 8.3, fronto-orbital width 5.3 mm. 
Type locality . — Laysan, May, 1902; 1 male (Cat. No. 29530). 
This species, while it has the general appearance of a 
Phymodius, especially of P. sculptus, in its naked carapace 
and chelae and bristly legs, differs from that genus, as pre- 
viously known, in the granulation of the surface, in the 
union of the frontal and orbital angles, in the equal cheli- 
peds, and indistinct spooning of the fingers. 
Chlorodopsis areolata (Milne Edwards). 
Chlorodius areolatus Milne Edwards, Hist. Nat. Crust., 
I, 400, 1834. 
Etisodes cselatus Dana, Crust. U. S. Expl. Exped., 1, 188, 
1852; pi. ix, fig. 4, 1855. 
Chlorodopsis areolatus A. Milne Edwards, Nouv. Arch. 
Mus. Hist. Nat. Paris, IX, 1873, 231, pi. vm, fig. 8. 
Hawaiian Islands, A. Garrett, 1 female, in Museum of 
Comparative Zoology. 
I think that A. Milne Edwards is correct in his surmise 
(op. cit., p. 235) that E. cselatus Dana is the same as Chlorodius areolatus of the elder Milne Edwards, 
and should be retained in Chlorodopsis rather than in Etisodes. 
The Hawaiian specimen measures 11 by 17.8 mm., fronto-orbital width 11.6 mm. Its antennal 
flagellum is excluded from the orbit more by the wide contact of upper and lower angles of orbit than 
by the extension' of the basal joint into the hiatus, differing in this regard from the figures both of 
Dana and A. Milne Edwards.
