REPORT ON THE ANNELIDA.

latter is also brownish, with the oblique pale region within the marginal blackish-brown 
belt. The maxillae (Fig. 32) are gently curved. The great dental plate has four teeth 
on the left and three on the right. The left paired lateral plate has five or six, and the 
unpaired six teeth, while the right lateral has eight. Only a single flattened j^late 
follows the paired lateral on each side. , The dentary portion of the mandible (Fig. 33) 
is much produced laterally at the tip, the region having a rhombohedral aspect, with the 
long axis oblique. 
The branchiae are represented by a simple filament on the fourth segment, and soon 
attain considerable dimensions. At the tenth foot the branchial process has seven 
divisions, and the same number appears on the twentieth (PI. XXXYII. fig. 19). The 
branches diminish to four on the fortieth foot, the same number also occurring on the

fiftieth. The branchiae continue to the posterior end of the body, increasing both in 
length and in the number of the divisions some distance in front of the tad. 
The dorsal cirri have very distinct articulations (PI. XXXVII. fig. 19). The ventral 
cirri present no feature of note. They are thicker in front, more elongated posteriorly. 
The foot in the anterior region of the body is provided with two strong yellowish 
spines, the points of which project beyond the skin. The brush-shaped bristles aie less 
distinct than usual. The long simple bristles conform to the ordinary type. The 
compound forms (PI. XTXa. fig. 12, from the twentieth foot) have the tip of the shaft 
ddated, serrated on the convex side, and with a comparatively limited striated region. 
The distal portion has the first hook larger than the second, and, as in the figure, the
