162 Descriptions of Three New Species of American Crabs. 



Length of type, 12 ; width, 13.3 ; exorbital width, 12.1 mm. 

 Distinguished by deeply areolated carapace, strongly angulated side- 

 margins and narrow front from all other species of the broad-fronted group. 



Pinnaxodes meinerti sp. nov. 



Type. Male. Valparaiso, Chile; Mr. Kroyer, collector. 



Near P. hirtipes Heller,* a specimen of which, from Port Otway,f is used 

 for comparison. Carapace of our species wider ; segments of legs shorter 

 and broader ; abdomen of male tapering from third to seventh segments, 

 sixth not constricted ; outer maxilliped of different form, merus joint taper 

 ing rapidly to distal end. 



Length of type, 6.8 ; width, 7.9 mm. 



Lophopanopeus nicaraguensis sp. nov. 



Type. Male. Realejo, west coast of Nicaragua ; Mr. OErsted, collector. 



Carapace crossed by transverse lines of coarse granules, on front, on 

 epigastric lobes, 2 on each protogastric region, one at widest part of meso- 

 gastric region ; on posterior branchial area a nearly longitudinal row of 

 very short granulated rugse which extend to posterior margin. 1 



Front little more than J width of carapace, median notch V-shaped, lobes 

 most advanced near the notch, outer angles dentiform. 



Antero-lateral teeth 5 (orbital included), thick, upturned, increasing in 

 size from first to fourth. From the second a crest extends to buccal angle ; 

 fourth and fifth cristate above. 



Chelipeds very unequal. Granules of palm form transverse reticulating 

 lines ; tubercles form two rows above, and near wrist tend to make longi 

 tudinal rows on outer surface. Fingers of large claw gaping, large basal 

 tooth on dactylus, thumb deflexed. 



Superior crest of carpus of legs unevenly granulate. 



Length of type, 8.7; width, 13 ; width of front, 3.5 mm. 



The ornamentation of the surface, the prominence of the lateral teeth 

 and the absence of lobes from the carpal crests of the legs, distinguish this 

 species from others on the west coast of America.
