Actsea variolosa Borradaile. 
Actsea variolosa Borradaile, Fauna and Geogr. Maidive & Laccadive Arch., I, pt. 3, 256, text fig. 
54, 1902. 
Auau Channel, 43 to 32 fathoms, station 3872; Necker Island Shoal, 16 to 171 fathoms, station 
3975; vicinity of Modu Manu, 20 to 21 fathoms, station 4168. 
Length of male, station 3872, 8.6 mm., width 12.1 mm. 
These specimens agree with Borradaile’s description, except that the carapace is a little wider. 
The black color of the immovable fingers extends back on the palm to about the middle of the propodal 
joint. 
Actaea nodulosa White.

Actxa nodulosa Alcock, Jour. Asiat. Soc. Bengal, LXYII, 1898, 148. 
Distribution . — Auau channel, 32 to 43 fathoms, stations 3872 to 3873; Penguin Bank, 14 to 29 
fathoms, stations 4031 (type locality), 4032 to 4034; northeast coast of Hawaii, 50 to 63 fathoms, station 
4063; Aleunihana channel, 49 to 176 fathoms, station 4066; vicinity of Modu Manu, 20 to 33 fathoms, 
stations 4148 and 4158. 
Honolulu reefs (Miers). 
In the series collected are several specimens larger than before noted; the largest male is 12 mm. 
long and 20 wide, the largest female 12.8 by 21.5 mm. 
The greater part of the tubercles of the surface are berry-like, covered with granules, either squa- 
miform or acorn-shaped. Chelipeds unequal in the male only; arms high as long, upper margin with 
two very irregular lobes, on which the granules are sharp; wrist with a moderate tubercle at inner 
angle and a smaller one below it. Tubercles of palm arranged more or less longitudinally, those of 
the 3 or 4 uppermost rows very prominent. Fingers very deeply grooved, their basal half roughened, 
tips acute, when closed leaving a very narrow interspace at base. Dark color of index in male only 
running far back on palm, almost to proximal end. On the legs the tubercles of the upper surface 
are elongated into cylindrical spines. Dactyls and lower surface and distal end of propodi tomentose. 
Color . — “Coral red and pink mottled.” 
The very prominent conical lateral lobes give this species a Xantho - like aspect. 
Actsea hawaiiensis, sp. nov. 
(PI. ix, fig. 9.) 
Hawaiian Islands, A. Garrett, 1 male type, in U. S. National Museum (Cat. No. 30523), 2, male 
and female, in Museum of Comparative Zoology. 
A narrow species, somewhat Pilumnus-\ihe, convex, not lobulated, posterior two-fifths scarcely 
areolated. Regions deeply separated from each other. Surface covered with scaly granules or tuber- 
cles, larger on branchial and hepatic regions; sparsely hairy, hairs yellow in alcoholic specimens. 
Protogastric and branchial regions partially subdivided by shallow grooves. 
Front moderately deflexed, with deep V-shaped emargination, lobes very oblique. Orbits with 
two Vs above and one below outer angles. Antero-external angle of basal antennal joint not nearly 
reaching tip of lower angle of orbit. 
Antero-lateral margin dentate and resolvable into four teeth besides the orbital; edges granulated. 
Some of these teeth may be subdivided into 2 or 3, except the last, which is narrow, simple, and most 
upturned. Postero-lateral border equal to chord of antero-lateral border minus posterior tooth. 
Wrists and hands coarsely granulate and sparsely hairy, like the carapace; granules somewhat in 
rows. Fingers elongate, pointed, gaping at base, light brown in alcohol, largest tooth at middle of 
pollex; dactyls granulate above at base. Color of pollex running far back on palm, in male only, 
where on lower margin it reaches middle of palm. 
Ambulatory legs fringed with hair above; carpal and propodal joints coarsely granulate, the former 
with a longitudinal groove above. 
Dimensions . — Type male, length (to tip of frontal lobes) 13.5, width 18.9 mm.; largest male, 19.5 
by 26.6 mm. ; female, 19.5 by 26.6 mm. 
This species has somewhat the shape of A. lata Borradaile, but its sides are more strongly dentate, 
front more deeply emarginate, fingers longer.
