MARINE CRUSTACEANS. 207 
Taken at Goidu, Hulule and Minikoi, on the shore in each case. At the latter island 
it was sheltering in a coral block on the outer reef. 
I have called this species after my friend Mr C. Forster Cooper, who was a member of 
the Expedition. 

Fic. 38. Thalamita pilumnoides; a, outside of chela. 
14. Thalamita pilumnoides n. sp. 
Diagnosis: “A Thalamita with the body and limbs very hairy; the ridges of the back 
much as in 7’. admeta; the front bent downwards, slightly arched, and bilobed, the angles 
of each lobe being slightly produced; the inner supraorbital lobes nearly straight, sloping 
backwards and inwards, less than half the width of the frontal lobes; side-teeth four in 
number (including the orbital tooth), the third being the smallest; the hinder edge of the 
carapace concave, forming a gentle curve with the side edge; the sixth abdominal segment 
of the male broader than long; the basal joint of the antenna about equal to the orbit 
in width, its crest with four blunt teeth; the chelipeds stout, unequal (in ~ at least), 
with three granular ridges on the outside of the hand, the areas between the ridges smooth, 
the under side smooth, the upper side covered with sharp tubercles, a row of three teeth 
along the inner edge of the upper side and one tooth at the articulation with the wrist, 
the fingers shorter than the palm, the wrist with one spine at the inner angle and three 
smaller ones on the outside, while the upper side bears some granules as on the hand, the 
arm with a series of teeth on its fore edge, diminishing from without inwards, and part 
of the upper surface granular; a spine on the hinder edge of the last meropodite and two 
or three spinules on the hinder edge of the last propodite.” 
Length, 4 mm.: breadth, 6°5 mm. 
Colour in spirit, pale yellow with minute green spots in places, especially on the front.
