150 RATHBUN 



Dimensions of feinale. — Length, measured from tip of longest 

 frontal spine, 6,7 mm. ; width 4.8 mm. 



Locality. — jMangroves, Parahyba River. 



Colo?'. — White, with marblings of orange-brown ; a narrow median 

 stripe of white extends from the posterior margin to a point in advance 

 of the lateral spine. There is an irregular oblong patch of white on 

 each branchial region, and in front of it a smaller transverse patch, 

 and a third still smaller near the lateral spine. 



MiJller's figure is of a small individual, and shows the frontal teeth 

 shorter, the carpus without spines, the fingers short as in our specimen ; 

 the color marks in general resemble those of our specimen, but in the 

 latter the light median stripe is not continued to the front. 



Family CALLIANASSIDJE. 



GLYPTURUS BRANNERI sp. nov. 



PL VIII, figs. 5-S. 



Dorsal suture very deep. Front with a short, acute, depressed ros- 

 trum, and on either side above the insertion of the antennae, a shal- 

 lower subacute projection. 



Eyestalks subtriangular, with convex upper surface, and contiguous 

 nearly to their narrow truncate extremities, which ai'e obscurely dentate. 



Terminal joint of the peduncle of the antennulae about i| times as 

 long as the penult joint. AntennuljE nearly as long as the carapace. 



The peduncle of the antenna is more slender than that of the an- 

 tennula ; its penult joint reaches the middle of the terminal joint of the 

 peduncle of the antennula. The flagellum is more than twice as long 

 as that of the antennula. 



Outer maxillipeds similar to those of G. acanthochirus ; the 

 ischium and merus are wider, the propodus somewhat longer and nar- 

 rower, the dactyl us more slender than in that species. The outer sur- 

 face is pubescent, the inner margin long-hairy. 



The larger cheliped is finely and inconspicuously dentate on its lower 

 margin. The merus is twice as wide as the ischium. The carpus is 

 nearly as wide as the manus, and twice as wide as long. The palm 

 is nearly as wide as long. The fingers cross when closed. The dac- 

 tylus has three teeth on the prehensile edge. Smaller cheliped with 

 the carpus and manus less than half as wide as in the larger cheliped, 

 and elongate. Both chelipeds have tufts of long hair on the margins. 



Inner caudal lamella as broad as long. Outer branch of the outer
