56 THE BRACHYURA. 
Pilumnus globosus Dana. 
Pilumnus globosus Dana, Proc. Acad. Nat. Sci. Phil., 1852, 81; Crust. U. S. Expl. 
Exped., 1852, 1, 236; atlas, 1855, pl. 15, fig. 10. De Man, Notes Leyden Mus., 1890, 
12, 59, pl. 3, fig. 3. 
Papeete, Tahiti; reef; Sept. 28, 1899; 1 adult ?, little smaller than 
the type, measuring 6.2 mm. long and 8 mm. wide. It differs a little from 
de Man’s description. The hairs of the carapace arise from rather large 
and irregular punctae; granules few. The margin of the front continues 
the arch of the antero-lateral borders, and has a wide emargination. The 
three lateral projections are not granules, but small spines. Palms granu- 
late all over the outer surface, but not thickly so; fingers grooved; basal 
half of dactylus granulate in both chelae, and one or two granules on outer 
surface of immovable finger. Fingers light brown; the color line on the 
propodus is at right angles to its lower margin; the pollex is as broad at 
base as it is long. 
Pilumnus tahitensis de Man.

Fakarava Id., Paumotus; outer reef; Oct. 12, 1899; 1 d, 2 2. 
The largest specimen, an ovigerous ?, is smaller than the types, 
measuring 6.8 mm. long by 9 mm. wide. The chelipeds are equal in 
all the specimens.

pl. 11. fig. 7. 
Papeete, Tahiti; reef; Sept. 28, 1899; 1 2. 
Fakarava Id., Paumotus; outer reef; Oct. 12, 1899; 1 2. 
Carapace convex, not much broader than long, thick; side margins 
entire, granulate, with faint traces of one or two teeth; surface smooth to 
the naked eye with scarcely any trace of regions, and with a few scattered 
hairs; under the lens the anterior two thirds is seen to be very sparsely 
and finely granulous. 
Front with two oblique lobes separated by a median V, outer angles
