der and graduated. On the posterior branchial segments there are 

 three pairs of gills with 4 branches ; 3 with 3 ; 2 with 2 ; and 1 

 with 1 cirrus. They end at about the end of the anterior third of 

 the body, or near the 30th segment, leaving about 125 segments 

 without any. Ventral ciiTus anteriorly is long and tapered ; on the 

 1st segment about equal to the dorsal cirrus. Upper caudal cirri 

 long and slender, about like the tentacular cirri ; lower ones short. 



Capillary seta? are long and slender with fine long tips; brush-shaped 

 setfe are few, with elongated marginal processes and about 6 inter- 

 mediate line denticles and strioe. Acicula 2, yellow, spiniform, hardly 

 acute, unequal, about twice as thick as the compound seta? ; the lat- 

 ter are short, their blades have ratios of breadth to length of 1 : 4-1 : 6, 

 limbate, tip onl}-^ slightly incurved, with a tooth below it, standing 

 nearly at a right angle ; another small tooth stands near the base ; 

 the edge of the limbus is finely serrulate, as is the inner distal mar- 

 gin of the head of the shaft. 



Length, about 100""^ (mutilated posteriorly); breadth, 2™°^ to 



Only one specimen was found. 



Leodice stigmatura, sp. nov. 



A long, slender species with long, very slender, partially or dis- 

 tally annulated antennae and tentacular cirri ; long slender dorsal 

 cirri; digitate branchioe, the larger with three to five slender cirri, 

 and bifid or simple branchial cirri present to about the 100th seg- 

 ment. Caudal region with two or four rows of distinct, round 

 blackish spots. 



Head with two lobes, separated but little by the frontal notch ; 

 each lobe is usually very obscurely divided by a slight transverse 

 indentation into an upper and lower half (head quasi-4-lobed). 

 Eyes rather large, black ; median antenna very long and slender, 

 scarcely tapered ; the basal half obscurely divided by shallow 

 grooves into rather short joints, but the distal part has more evident 

 and longer articulations, the distal six joints forming about half its 

 length ; it extends back in some specimens to the 15th setigerous 

 segment, but more often about to the 5th, varying according to the 

 degree of contraction of the segments; it is about five times as 

 long as the head; inner paired antennae similar, but somewhat shorter, 

 reaching in some cases the 10th segment, in others to the 3d. Outer 

 antennae about one-quarter as long as the median, more distinctly 

 annulated, with about 10 annuli, the distal four forming half the
