A small individual 10 mm. long is believed to represent this species, 

 the original description of which was based upon a probably imperfect 

 and much contracted specimen. There are, however, some points of 

 difference between the two specimens, as the following brief descrip- 

 tion indicates. 



The form is strongly depressed, about equally rounded anteriorly and 

 posteriorly, the somites munbering 21, strongly marked and well 

 developed throughout. The subanal lobes or cirri are large, thick and 

 fleshy. The dorsal smooth field is about \ the entire width and not 

 subdivided into areas. A black spot or group of spots occurs on the 

 posterior part of each segment behind the second gill. 



The caruncle is short and broad , reaching from the anterior margin of 

 II to the posterior margin of IV, and consists entirely of a rather high, 

 thick crest, little free behind. The median tentacle equals the caruncle 

 in length and the stout basal article, which furnishes | of its length, 

 nearly equals the caruncle in thickness. The terminal piece is fila- 

 mentous. The dorsal eyes are very large, elongated and black. The 

 ventral eyes are coalesced and the ventral paired tentacles minute. 



The dorsal cirri are very long, much exceeding the length of the 

 caruncle, slender and tapered. The median cirrus arises between the 

 second and third gills and, like the ventral cirrus, is stouter than tlie 

 dorsal cirrus and equally long. Five pairs of gills occur on the middle 

 region. They are arbusculate and spreading, with some 30 or more 

 slender, lanceolate terminal twigs formed by as many as 5 or 6 irregular 

 dichotomous divisions. The setae agree exactly with Johnson's figures.

The addition of this species to the list of Alaskan poly chutes becomes 

 possible through the study of the contents of salmon stomachs sub- 

 mitted by Dr. H. M. Smith. The salmon were taken at Yes Bay, 

 Alaska, on July 27 and 28, 1905, and contained a large number of
