56 THE BRACHYTJRA. 



Pilumnus globosus Dana. 



Pilumnus globosus Dana, Proc. Acad. Nat. Sci. Phil., 1852, 81; Crust. IT. S. Expl. 

 Exped., 1852, 1, 236 ; atlas, 1855, pi. 13, fig. 10. De Man, Notes Leyden Mus., 1890, 

 12, 59, pi. 3, fig. 3. 



Papeete, Tahiti; reef; Sept. 28, 1899; 1 adult 9, 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 <?, 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.

Actaeodes ? integerrimus Dana, Crust. U. S. Expl. Exped., 1852, 1, 201 ; atlas, 1855, 

 pi. 11. fig. 7. 



Papeete, Tahiti ; reef; Sept. 28, 1899; 1 ?. 



Fakarava Id., Paumotus; outer reef; Oct. 12, 1899 ; 1 9. 



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
