MAIOIDEA. 



TlARINIA ANGTTSTA. 



Maris : Carapax angustior, pone oculos vix constrictus, latitudine 

 maxima multo breviore quam longitudo post~orbitalis, latitudine trans- 

 orbitali parce minore quam latitude maxima; rostro longo, cornubus 

 apice conspicue' divergentibus et latera cum 34 dentibus minutis 

 remot^ armatis. Antennce externce rostro dimidio breviores, artic'ulis 

 2do Stioque tenuibus. Manus tenuis, digitis omnino contiguis. Pedes 

 8 postici pubescentes, secundi Stiis duplo long lores articulus Stius 

 par is antici plus minusve tuberculatus. 



Male: Narrow, tuberculate and granulous above, hardly constricted 

 behind the eyes, medial region hardly prominent, greatest breadth 

 much shorter than post-orbital length, and but one-fourth greater 

 than trans-orbital breadth ; beak long, horns rather strongly diver- 

 gent at apex, three or four minute teeth remote from one another, 

 set along the outer side of lower half of beak. Outer antennae half 

 shorter than beak, second and third joints slender. Hand slender, 

 fingers throughout contiguous or nearly so. Eight posterior feet 

 pubescent; second pair twice as long as following; third joint of 

 anterior pair sparingly small tuberculate. 



Plate 3, fig. 7 a, male, enlarged three diameters ; b, outer antennae. 

 Dredged up off Sooloo Harbour. 



Length, six lines; greatest breadth, two and a half lines; beak, 

 two lines long ; distance between tips of orbital acanthi, two lines. 



This species is much narrower than the others, and has the beak 

 one-third the whole length, with the tips much divergent. The dis- 

 tance across the eyes, instead of being half the greatest breadth, is 

 about three-fourths the same. Behind the cardiac prominence, which 

 consists of three tubercles, there is another similar but smaller promi- 

 nence on the intestinal region. The beak is hairy, as usual, and there 

 are a few short hairs at the tip of the orbital acanthus. The teeth on 

 the outer side of the beak are minute and hardly seen without special 

 care on account of the hairs.
