organs, numbered II-l to II-6 (pi. 7). Those on II-l are short, with 

 blunt tip and subapical pore (fig. 1). Those on 2 are large, sharply 

 falcate, with entire tip and subapical pore (fig. 2). Those on II-3 are 

 similar to those on 2, but less falcate (fig. 3). Those on II-4 and 5 are 

 erect, with a large lateral tooth (figs. 4, 5) and a pore near the tip. 

 Those on II-6 are slender, erect, distally entire and with a distal pore 

 (fig. 6). All those shown on plate 7 were taken from the same series 

 and drawn to the same scale. The organs on area III occur in a single, 

 longitudinal row; they are low, broad processes, their long axis at 

 right angles to that of the body and their single, large spine directed 

 ventrally; they resemble those shown for other species of Glycinde. 

 Area IV is provided with 2 rows of knobbed organs (figs. 8, 9) ; they 

 lack a pore; each has 3 short processes and a much larger one near the 

 center. Area V has a single row of long, triangular pieces that are dis- 

 tally bifid and each has a pore near the base, on the medial side (fig. 7). 



Parapodia are well developed and are directed laterally. Notopodia 

 are small and inconspicuous; they are first present from segment 25 

 and gradually increase in size going back. In anterior, uniramous seg- 

 ments both dorsal and ventral cirri are large (fig. 14). Here both 

 presetal and postsetal lobes are about equally long or the presetal one 

 is slightly the longer. These parapodia are provided with single yellow 

 acicula and about 31 spinigerous, composite setae; they are arranged in a 

 fan-shaped fascicle. The dorsal cirrus is incised near its tip, much as in 

 G. polygnatha (see above). 



In biramous parapodia both dorsal and ventral cirri decease in size 

 but the first continues to have a slight incision subdistally. Notopodia 

 are armed with single, heavy acicula and few (3 or 4) acicular hooks 

 that are distally falcate and provided with a long, slender hood, as 

 typical for most species of the genus. Posterior neuropodia come to be 

 larger and longer than those in anterior segments. The presetal lobe is 

 long and far surpasses the postsetal one but it is never chordate in out- 

 line. The ventral cirrus is short and directed ventrally. Neurosetae in- 

 clude about 6 supra-acicular, and 7 subacicular composite spinigerous 

 ones. Neuroacicula occur singly; they are pale yellow and slightly 

 thicker than notoacicula. 



The composite, spinigerous setae have the spinelets extensively dis- 

 tributed along the appendage. The shaft is long and cylindrical; at its 

 distal end it widens to accomodate the basal end of the appendage. The 

 distal end of the articulation is sharply dentate at its long, or outer edge ; 

 it has about 8 teeth (figs. 12, 13) and the sides slope gradually to the 

 smooth concavity in back. The appendage, at its greatest development is
