Chlorodopsis scabricula (Dana). 
Pilodius scabriculus Dana, Crust. U. S. Expl. Exped., I, 220, 1852; pi. xii, fig. 9, 1855. 
Honolulu, 1891, 1 immature male. 
The regions are faintly areolate, minutely scabrous, grooves smooth, lateral projections spines 
(except the orbital), spine E much smaller hut similar to the others. 
A row of four lobules parallel to the margin; a similar lobule at 2L. 
Lobes of front sinuous, entire to the naked eye, minutely granulous under the lens,, outer angle 
well marked, but not spiniform nor very prominent. 
The outer projection of. the basal antennal joint reaches as far as the end of the suborbital tooth, 
but does not exclude the flagellum from the orbital gap. 
The tubercles of the wrist and upper surface of palm are large, conical, acute. Upper margin of 
legs spinulous. 
Dana says “tooth E nearly obsolete, hand and carpus very minutely tuberculate.” In spite of 
these discrepancies I place the specimen under C. scabricula until the species shall have been better 
worked out. 
Our specimen agrees very well with A. Milne Edwards’s description and figure of C. spinipes, but 
it is not the C. spinipes of Heller and de Man, in which the orbit has a spine below the outer sinus, 
nor C. spinipes Alcock (Jour. Asiatic Soc. Bengal, LXVII, 1898, 169, ubi syn.), in which the outer 
angle of the front is spine-like and the carapace coarsely granular. 
Chlorodopsis aberrans, sp. nov. 
Carapace about three-fifths as long as broad, posterior third not subdivided. Regions and sub- 
regions fairly well marked; protogastric lobes lightly and incompletely subdivided. A groove running 
inward from the penult lateral sinus to the gastric region, otherwise the branchio-hepatic region 
is undivided. Surface covered with sharp tubercles, 
irregular in size, as a rule diminishing from in front 
backward and becoming granules on the postero-medial 
region. Surface sparingly hairy. 
Frontal lobes broad, rounded, granulated, separated 
by a U-shaped median sinus; a small lobe at outer an- 
gle, distinct from the less advanced orbital angle. 
Orbital margin spinulous; outer emargination of good 
size. 
Antero-lateral projections four, the first a narrow 
granulated lobe below the level of the orbital angle; 
the second, third, and fourth, stout spines with granu- 
lated borders. 
Lower surface of carapace much like the upper. 
Outer angle of basal antennal joint prolonged a little 
into the orbital hiatus, but not excluding the flagel- Fig. 20— Chlorodopsis aberrans, type male, a, Dorsal

inner lower tooth of orbit. 
Chelipeds in a male a little unequal; exposed surfaces covered with conical sharp-pointed tubercles 
which on upper margin of arm, hand, and inner angle of wrist become elongate and spiniform and 
more or less curved.. Tubercles of hand continued halfway along the deeply grooved fingers, which 
shut tight, their acute tips overlapping. Dark color of thumb in male continued a little way back on 
palm. 
Legs finely granulate, sparingly hairy, margin spinulous. 
Dimensions. — Male, length 4.7, width 8 mm. 
One specimen only, a male, was taken in the vicinity of Modu Manu, 23 to 26 fathoms, station 
4146 (Cat. No. 29434). 
This species, although not a typical Chlorodopsis by reason of the sharp fingers, nevertheless has 
much in common with C. woodmasoni Alcock, which is more deeply areolated and not so sharply 
granular.
