OeNONE TELURA, Sp. nov.^ 



Plate 62, fig. 2-5. 



The color of the type at present is a brownish grey, appearing to have been 

 partially bleached in preservation. 



The body is comparatively short, widest in the middle region and narrowing 

 at the ends, the caudal region being the more slender. The body is strongly 

 arched dorsally and much more weakly convex ventrally. The neural furrow 

 is but shghtly indicated. The length is about 60 mm., the body, however, 

 being in a strongly contracted condition, apparently from having been dry at 

 some time. The greatest width, exclusive of parapodia, is 3 mm. The total 

 number of somites is in the neighborhood of 208. 



The prostomium in outline as viewed from above is subsemicircular, but 

 evidently longer than wide. It is flattened dorsoventrally, and is deeper pos- 

 teriorly than anteriorly. The surface appears to have been wholly smooth, a 

 certain present wrinkhng being apparently due to shrinkage, and it lacks all 

 trace of appendages. The eyes are covered in the type. The lateral ones are 

 very much the larger, and are elliptic and somewhat obhque. (Plate 62, fig. 3). 



There are, following the prostomium, one complete achaetous and non- 

 parapodia-bearing somite and one somite incomplete above. The relations of 

 these two somites to each other seem to be as follows: the second one is obht- 

 erated above and laterally, but is distinct and sharply limited by deep furrows 

 ventrally, where it appears like the corresponding region of succeeding normal 

 somites; the first somite is much longer and is similarly decidedly longer than 

 the third somite, but shorter than the third and fourth together; it is weakly 

 divided dorsally by a transverse furrow, the two divisions equal, is wholly smooth 

 on the sides, and is ventrally again divided by a transverse furrow that lies much 

 nearer to the caudal margin than to the anterior margin, the anterior division 

 being carried conspicuously forward as a lower lip. The anterior margin of 

 the lower lip is straight. The lateral margin of the somite on each side is a little 

 concave and the dorsal margin is straight. (Plate 62, fig. 3). 



The ordinary metastomial somites are very short and closely crowded.
