Hermite Island, Tierra del Fuego. Obtained by Lieut. Case. 



^ Length, two and a half to three inches. Colour, deep red, or red 

 faintly brownish. Carapax with a moderately long beak (less than 

 half the carapax in length), anterior angles spini-acute, on upper 

 surface behind beak two spines, sides with about six small acute teeth, 

 median area with defined outline; outer an tennse longer than carapax. 

 Anterior feet naked, or nearly so, narrow, very scabrous, apices of 

 carpus and arm with several spiniform teeth, hand not stouter than 

 carpus, inner margin spinulous, outer unarmed, finger exceeding half 

 the length of hand, extremities of fingers incurved. Six following 

 feet subequal, moderately pubescent. Fifth pair in its folded con- 

 dition not half as long as carapax. Segments of abdomen laterally 

 acute. 



Of the transverse ciliated lines of the carapax, the four posterior 

 extend quite across the carapax ; the first of these four is partly in 

 the line of the boundary, enclosing the median area ; anterior to this 

 boundary there are three ciliate lines crossing the area. Joints of 

 abdomen similarly marked. For extremity of abdomen, see figure b. 

 The first abdominal segment has no appendages in the female ; the 

 segment lies partially under the preceding and following. 



The maxillipeds when thrown forward reach a little beyond the beak; 

 second and third joints largest, the third with a few hairs near base ; 

 last three joints nearly cylindrical. The thoracic segment to which 

 the fifth pair of legs is attached has free motion like the following 

 abdominal segments.
