Among a collection of annelids made by Capt. R. A. Bartlctt in 

 Alaska during the summer of 1924, under the auspices of the National 

 Geographic Society, and submitted to me for examination by Dr. 

 Waldo L. Schmitt of the United States National Museum, was a 

 single specimen belonging to the genus Enipo, which apparently 

 represents a new species. The specimen is entire, but has lost all of 

 its elytra, so that I am unable to give any details of these latter 

 organs. 



The other annelids represented in the collection were HarinotJioe 

 imbricata Linnaeus, Eunoe harhata Moore, Nereis pelagica Linnaeus 

 and Neplithys, species. The material was dredged at three different 

 localities: About 15 miles north of Big Diomede Island, Bering Strait, 

 June 14, 1924; south of Big Diomede Island, and in the mouth of 

 Kotzebue Sound, July 10 and 12, 1924, 12-17 fathoms. From south 

 of Big Diomede Island but one mutilated and hence questionably 

 determined Nereis pelagica was obtained; otherwise the species were 

 found at each of the other localities, except the new species which 

 was taken only in Kotzebue Sound, and the fragmentary Nephihys 

 from north of Big Diomede Island. 



Genus ENIPO Malmgren
