Carapace ovate, subglobose ; greatest height equal to nearly three-fourths of the length. 

 Dorsal margin very strongly arched, or even angular, highest in the middle; ventral 

 mar-in st might or slightly convex. Extremities rounded and nearly equal. The dorsal 

 aspect of the carapace is very broad, subglobose, pointed in front and very broadly 

 roundel behind, broadest near the middle: length about one-third greater than the 

 breadth. End view subcircular. Lucid spots four, quadrangular, crowded : three set 

 transversa^ in front, and one behind. The shell is smooth and shining, distantly punc- 

 tate ; colour a transparent yellowish or olive-brown, clouded with patches of darker hue, 

 which often form faint striae (fig. 21) arranged as in C. vidua. These strise, however, are 

 mostly absent or reduced to one or two faint dorsal patches. The filaments of the upper 

 Uitenn® axe eight or nine in number. The lower antennaa have three excessively long 

 ■eta; (Plate XXXVI. fig. 5), measuring more than twice the length of the apical portion 

 Of the antennae, reckoning from the origin of the setaa to the extremity of the ungues. 

 The postabdominal rami are rather stout, their claws sharply curved at the apices. The 

 setae of the second feet as in C. compressa.

Cvrius cinekea, n. sp. (Plate XXIV. figs. 39-42, and Plate XXXVI. fig. 7.) 



Carapace oval, tumid, higher in front than behind ; greatest height equal to nearly 

 two-thirds of the length. Anterior margin broad and well rounded, posterior narrowed 

 ana rather obliquely rounded. Ventral margin straight or very slightly incurved, dorsal 

 terming a flattened arch and sloping more steeply behind than in front. Seen from 

 Mm e the outline is rhomboidal or lozenge-shaped, the greatest breadth in the middle, and 

 equal to more than half the length; from the middle the sides taper evenly toward the 

 extremit.es the anterior of which is acutely, the posterior obtusely pointed. End view 



iroadly oval, pointed above and below. The right valve considerably overlaps the
