LEODICE MAKEMOANA. 235 



exceeds its notocirrus only a little, but the following ones rapidly increase in 

 length and soon greatly^ exceed the cirri, in the widest region of the body fall- 

 ing but little short of attaining the middorsal line. From this region caudad 

 they again rapidly decrease in length, but they remain of nearly uniform length 

 in the middle and posterior region where they extend but about half way to the 

 middorsal line. The branchiae of the last three pairs rapidly decrease, the last 

 ones being but slight rudiments. (Plate 53, fig. 7-11). 



The acicula proper are two in number in each parapodium, the tips visibly 

 projecting on parapodia from the second inclusive caudad. They are pale in 

 color, the posterior ones scarcely darker than the first ones. The hind portion 

 of each is straight, slightly narrowing distad; the short projecting tip is slightly 

 curved, and subventrally directed. The crochets first appear on or near the 

 twenty eighth parapodia, projecting a shorter distance in anterior part of series 

 than in the posterior. Each crochet is in the distal half curved first greatly 

 cephalad and then a little caudad. The head may bear either two teeth, or a 

 reduced, supplementary, third tooth is more frequently present on caudal side of 

 the apical one. The apical tooth is a little curved forwards, the small one at its 

 base being vertical. The supplementary tooth is much stouter and longer and 

 stands either nearly at right angles to the axis or, in posterior region, it is more 

 commonly considerably reflexed proximad. The guards extend out over the 

 subapical tooth and rise to a little above the level of the apical one. (Plate 53, 

 fig. 6). The compound setae form a ventral group of usually three or four. 

 The shafts of these are long, gently curved, with the convexity cephalad, of 

 uniform diameter to near the distal end where clavately enlarged, the enlarged 

 portion unusually short. The appendage is a small narrow piece ending above 

 in a long, curved, terminal tooth; below this is a very small, subapical tooth; 

 below the subapical tooth the piece widens to an obtuse process, with upper edge 

 horizontal for a short distance from apex, leaving a very small tooth. The 

 guard is narrow, its free edge weakly concave. (Plate 53, fig. 5). The capillary 

 setae of the dorsal fascia much exceed the other setae in length ; they are distally 

 slenderly acuminate, being drawn out to a very fine tip; they are usually dis- 

 tally curved. The pectinate setae have the usual general structure. The distal 

 piece is proportionately broader and shorter than the average. The teeth 

 increase in length from one edge to the other, at which there is a much longer 

 process. (Plate 53, fig. 4). 



The maxillae are pale and small. Maxillae I have the united carriers form- 

 ing a plate somewhat shield-shaped; the caudal end rounded and mostly shal-
