except the caudal fan, as in this species. Telson as in Call. pug- 

 natrix, a little longer than broad, bilobed, with a small tooth 

 in the median notch, attached to the lower surface; lateral edges 

 with two spines posteriorly. Swiramerets not longer than telson. 

 Endopodite oval, not yet once and a half as long as broad, rounded 

 apically. Exopodite as in CalL praedatriw, but only one fifth longer 

 than broad ; additional series of spines as in Call. piignatrix^ strongly 

 arcuate and diverging much from the straight apical border, spines 

 as stout and as long as those of the rounded postero-external 

 angle of the exopodite. 



Flagella of internal antennae once and a half as long as their 

 peduncle, upper fiagellum twice as thick as the other. 



Larger chelipede as in Call. praedatriv, but the merus is twice 

 as long as broad, its sharp lower edge is armed with 8 slender 

 spines and the hand has no groove on the outer or inner 

 surface. 



Propodite of 3rd legs with obtuse lobe on the hinder edge, 

 the lobe measuring one seventh of the whole length of this joint 

 and the first of the three shallow notches on the lower margin 

 is farther distant from the distal than from the proximal extre- 

 mity of the margin.
