CRUSTACEA. 



gin is thin and terminates in the outer orbital angle ; and moreover it 

 is shorter than the postero-lateral margin. The aspect of the species 

 is neat. 



PANOP^EUS I^EVIS. 



Carapax Icevis, vix nitidiw, non bene areolatus, fronte fere recto, non 

 producto, minut^ emarginato, margine antero-laterali tenui, k-lobato, 

 lobis 2do Btio bene dentiformibus et acutis, margine em-urn postico 

 arcuato, 4to angustiore. Pedes antici valde incequi, inermes, supra 

 rotundati, manu Icevi, extus paulo nitidd, digito mobili Icevi, dente 

 magno basali carente. Pedes 8 postici tenues, marginibus pubescenti- 

 bus, articulo tertiofere nvdo. 



Carapax smooth, scarcely shining, not distinctly areolate, front nearly 

 straight, not produced, minutely emarginate, antero-lateral margin 

 thin, four-lobed, second and third lobes neatly dentiform and acute, 

 the posterior margin of these teeth arcuate, fourth narrower. An- 

 terior feet very unequal, unarmed, rounded above, hand smooth, a 

 little shining on outside, moveable finger smooth, without a large 

 basal tooth. Eight posterior feet slender, margins pubescent, third 

 joint nearly naked.

 front ; c, right hand, front view. 



Locality doubtful. 



Length of carapax of male, five and a half lines ; greatest breadth, 

 seven and a half lines; ratio of length to breadth, 1 : 1'36. The 

 anterior lobe of the antero-lateral margin has a thin margin and is 

 arcuate posteriorly; the outer angle of the orbit is scarcely salient. 

 The large hand is quite large, and there is a shallow sulcus near the 

 upper side. Faint traces of areolets 2 M may be made out. The 

 third joint of the outer maxillipeds is shorter than long, and has the 

 anterior margin concave.
