setose. Flagellum broken off. Secondary flagellura four- 

 jointed, about as long as the fifth joint of the peduncle. 



Second antennce with only one joint of the peduncle left, as 

 long as and somewhat stouter than the third joint of the first 

 pair, and bearing a few slender seta^, especially at the lower 

 extremity. 



Mandibles stout, with the basal portion subtriangular in 

 form. Right with its molar tubercle in the form of a hollow 

 crown, toothed all round the edge and with a few small seta3 ; 

 cutting-edge, which with the tubercle is directed forwards, 

 furnished with a row of five spines, very closely set, but not 

 clearly made out ; secondary plate strongly developed and 

 ending in two large teeth. Left %vith two strong protu- 

 berances on the secondary plate. Palp slender, three-jointed ; 

 first joint very short, second and third subequal, the former 

 with a row of about six or seven short sette on the lower 

 edge, the latter ending in a number of long seta3 and with a 

 tuft of two or three on its upper edge a little distance from 

 the extremity. ('Jlie other organs were very small and 

 fragile, and were unfortunately mutilated in dissection.) 



First gnathopods small ; carpos narrow-oblong, dilating 

 outwards to the distal end, fringed on its lower margin with 

 three or four bunches of setee ; propodos with three groups of 

 dorsal sette placed transversely and a tuft of setee at the 

 articulation of the dactylos, lower margin with seta sparingly 

 scattered along its edge ; palm oblique and not well-defined ; 

 dactylos slightly more than half as long as the propodos, 

 slender, slightly curved. 



Second gnathopods abnormally developed, nearly half as 

 long as the whole body ; basos long and somewhat curved, 

 especially on the posterior margin ; ischium quadrilateral, as 

 broad as and about one third as long as basos ; meros small, 

 triangular, with its lower side greatly produced into an acute 

 lobe, bearing a few setie near its extremity ; carpos very 

 much broader than long, also produced into a narrow trian- 

 gular prolongation, which extends as far as that of the meros 

 and bears one or two setse ; propodos about equalling in length 

 all the rest of the limb, widening to the distal end, which is 

 about half as broad as the length of the joint; dorsal surface 

 smooth and curved, ventral straighter, ending in a strong 

 tooth and with a few seta3 near the extremity, distal end 

 transverse, with a deep hollow inside the inner tooth, then 

 having a small irregular tooth near the middle which bears a 

 few set£e, and a slight protuberance at the hinge of the 

 dactylos ; the latter joint very long and falcate, with its inner 

 edge nearly straight for the first half of its length, then 

 sickle-shaped, its extremity reaching to the prolongations of
