front ; wrist subecjual to but wider than the hand ; the hitter 

 sli^'htly curved, the hind viaryin produced, forming a chelate 

 junction uith the duct y Jus ) hind margins of third, fourth, and 

 fit'fli joints densely setose. Second gnathopods : side-phites 

 olilong, widened l)eh)W : first joint about twice as \ou'r as 

 the second, which is kin;!;er than the third ; wrist much 

 longer and wider than the hand, hind margin very convex 

 and scabrous. Dactylus distinct. Las-f three pairs of percvo- 

 ]>ods simihn- in structure, the first joints wide and obscurely 

 crenate behind; the side-plates of the third pair wider than 

 deep. Third uropods : inner ramus not reaciiing the last 

 joint of the outer. Telson barely reachin.^ the end of the 

 peduncle of the tiiird uropods, deeply notched. 



PODOPRIONIDES, gen. nov. 



Ttesembks Pcdajwiohella^ G. O. Sars, in the chelate first 

 gnathopods and the deeply serrate first joints of the last 

 three })era'opods, but differs in the less compact body, the 

 structure of the mandibular palp and of the outer ramus of 

 the third uropods. From Pvdojirion, C'hcvreux, it differs in 

 having the first joint of the fourth and fiftli perteopods serrate 

 like the third. 



Podoprionides incerta, sp. n. 



W.Q. 2P/8/02. Hole 12, D net. One specimen: leigth 

 2 nun. 



Body not very compact : the anterior side-plates small. 



U}>per antennit nachmg a little beyond the j)eduncle of the 

 lower: aj>pcndage 2-jointed, the first twice as long as the 

 second, which has a tuft of very long setaj at the extremity. 



Lover antenhce: peduncle stout, margins of third joint 

 produced. Mandilndar palp icith the third joint more than half 

 as long as the .second, narrow, pectinate. 



J'irbt gnathoj'ods : side-plates less than half the length of 

 the first joint, rounded in trout, straight behind, witli a notch 

 and a spine above the angle. First joint rather longer than 

 the remaining five, widening distally ; second and third joints 

 .subequal ; wrist subequal to the hand ; the hind margin of 

 the hand is short, convtx and prolonged in a spine-like process, 

 which is slightly curved inwards to meet the point of the curved 

 dactylus, forming a completely chtlate joint ; palm very obliquej 

 smooth. 



tSecond gnathopods : side-plates oblong, about twice as deep 

 as wide, angles rounded. First joint hardly as long as the next
