than broad and slightly narrowed posteriorly. Eyes small, but con- 

 spicuous, wide apart, the anterior considerably farther apart than the 

 posterior ones. Palpi large in presex'ved specimens, broad ovate, and 

 well rounded anteriorly, in contact at their bases; but in living speci- 

 mens more elongated and oblong, exceeding the length of the head. 

 Antennffi (or tentacles) long and slender, distinctly and rather regu- 

 larly annulated, but not moniliform. Tentacular cirri, in preserved 

 specimens, similar to the antennae ; the upper ones are of about the 

 same length, but the lower are little more than half as long. Dorsal 

 cirrus of the second segment is as long as, or even longer than, the 

 antennoe. The dorsal cirri on the 3d, 4th, and 5th segments are 

 shorter, about equal, longer than the lower tentacular cirrus, and 

 about half as long as the dorsal cirri of the succeeding segments, which 

 are alternately longer and shorter, the longer ones about half as long 

 as the breadth of the body. While living, the alternate dorsal cirri 

 are usually held extended and curled up over the back. The two 

 anal cirri are long and slender ; in one preserved specimen they ai-e 

 more than twice the breadth of the body, while in the same specimen 

 the dorsal cirri on the second and third segments preceding the anal 

 one are considerably longer than those on the segments farther for- 

 ward. 



The setae are all compound, rather long, mostly considerably bent, 

 with a short, acute -triangular terminal piece, which is very distinctly 

 bidentate at the tip. 



Color of body, when living, deep salmon, or light yellowish orange, 

 with dark brown intestinal line, darker posteriorly ; eyes dark brown. 



Length, when living, about 25'""'; breadth, rS""".

This species, when living, was most brilliantly phosphorescent, 

 with a bright green light, so intense- as to be distinctly visible in 

 daylight, or close to a large kerosene lamp. — A. E. V.
