FIJI-NEW ZEALAND EXPEDITION 65 
A small land crab, Ocypoda ceratophthalma, was found on the 
sand beaches and also on the higher ground of Makuluva. This is 
quite a lively little crab that burrows in the sand but spends a 
good deal of its time wandering over the grass and among the 
fallen leaves under the trees. It is daintily colored, being very 
nearly a cream color in general; but the background on the cara- 
pace is conspicuously marked near its hind margin with a pair 
of scarlet blotches which tend to coalesce in the central line but 
are even there partly divided. The entire carapace is finely punc- 
tate. The pointed eye stalks are peculiar and extend well beyond 
the blackish eye which appears to be merely a basal swollen part 
of the stalk. The ‘‘fingers’’ are rather slender, thus differing 
from the truncated ones possessed by the West Indian, relative, 
O. gaudichaudei. These forms shed their claws very readily and 
are so agile as to be hard to capture. Another specimen of this 
species had very large and prominent black eyes in striking con- 
trast to the general pallid coloration of the carapace. 
Trapezia digitalis is a minute erab densely hirsute, reddish in 
color with black fingers. The hairs are red basally and ivory 
white toward the ends. The chele are very broad and the eyes 
are small. 
Actwa tomentosa is on ovoid form in which the antenne fold 
transversely and the appendages are adapted to walking rather 
than swimming. It is very dark colored, almost black, and con- 
spicuously carunculated; the caruncles themselves are strongly 
tubereculate. Many of the caruncles are squarish in form and tend 
co arrange themselves in transverse rows on the carapace. The 
legs are quite hairy, and the eyes small, flush with the surface, 
their stalks granulated so as to be scarcely visible when the eyes 
are retracted. The antennules are mere slender filaments. 
The family Grapside is represented by Percnon planissimus, 
allied to the ‘‘Sally light-foot’’ of the West Indian region. This 
form of rock crab is very greatly flattened and has the art of 
concealment and of dodging into remarkably narrow crevices, de- 
veloped to perfection. It is smaller than its West Indian rela- 
tives of the genus Grapsus. The carapace is densely granulated 
and a clear dark olive in color. The legs are conspicuously striped 
with yellow, the distal joints are barred with the same color, 
showing in sharp contrast to the dark green. There is a group of 
sharp rostral spines, and the front edges of the legs, particularly 
the meri, are also ornamented with a row of strong thorny spines.
