498 MICROMALDANE ORNITHOCHATA. 
being somewhat clavate and symmetrically rounded (elliptical). In lateral view it is 
irregularly clavate, the dorsal outline being smoothly curved and ending ventrally in 
the projecting snout, which slopes backward and slightly upward to the mouth. 
The body (Plate CX XX VI, fig. 18) is comparatively short, consisting of nineteen segments, 
seventeen of which are bristled. It is enlarged anteriorly, is cylindrical in the middle, and 
tapers posteriorly to the truncated posterior end. The middle region consists of two long 
segments. The caudal part is crenated from the various rings, and the acheetous last segment 
is truncated distally with a small papilla, probably representing the anus. Glands are 
distributed extensively in the body-wall. ; 
‘The bristles (Plate CX X XVI, fig. 18a) have the shape of a pointed assegai or sharp 
spear, the cylindrical shaft being stout, and the tip a flattened, translucent spear-point. 
The hooks (Plate CXXXVI, fig. 185) are minute, apparently few in number, have a 
rudimentary shaft, which enlarges into a bulbous shoulder, above which the neck is rather 
thick. The main fang is curved downward at considerably less than a right angle to the 
neck, and the crown of the hook is high, with five or six teeth above the large fang. In 
general shape these hooks somewhat resemble those of Lumbriclymene nunor, Arwidsson. 
No gular bristles are present in the specimen. Mesnil thought the hook resembled 
an avicular Sabellarian bristle, and that it showed the evolution of a Maldanid toward 
that group. Such views, however, are conjectural. He found one example containing 
greyish ova.
