THE HOLOTHURIANS OF THE NORTH PACIFIC COAST 

 OF NORTH AMERICA COLLECTED BY THE ALBATROSS 

 IN 1908. 



By Charles Lincoln Edwards, 



Of Trinity ('allege, Hartford, Connecticut. 



This paper is based on a collection of Holothurians made by the 

 Bureau of Fisheries steamer Albatross along- the north Pacific coast of 

 North America during the Alaska salmon investigations of 1903. The 

 collection contains eleven species, one of which, Chlridota alhatrossii, is 

 a new form. The specimens have been added to the general collection 

 of the United States National Museum. 



The s3'nony nw is given only for the species discussed. The literature 

 bearing on such forms is appended. In filling out the habitats I am 

 particularly indebted to the important work of Ludwig, published in 

 1900. 



I. CHIRIDOTA LiEVIS (Fabricius) 1780. 



June 20, 1903. — One tentacle-crown and one body fragment; Station 

 4193; lat. 49° 20' 30" N., long. 123° 35' 40" W.; 18 to 23 fathoms; 

 bottom, temperature 50.3°, green mud and fine sand. 



Habitat. — Eastern coast of North America from Massachusetts (lat. 

 42° N.) to Labrador (Ayers, 1852; Stimpson, 1853; Packard, 1860; 

 Verrill, 1861, 1866; Selenka, 1867; Bush, 1883; Lampert, 1885; 

 Ganong, 1884, 1886, 1890?; Whiteaves, 1901). West coast of Green- 

 land to lat. 69° N. (Fabricius, 1780; Liitken, 1857; Stimpson, 1863; 

 Norman, 1876; Duncan and Sladen, 1881; Ludwig, 1882). West and 

 north of West Spitzbergen to lat. 80° N. (Ljungraan, 1879). Nor- 

 wegian coast to Finmark (Vahl, 1806; M. Sars, 1850, 1861); Dan- 

 ielssen, 1861; Bidenkap, 1899; Ostergren, 1902). Murman coast 

 (Jarzynsky, 1885). Kara Sea (Stuxberg, 1886). Ludwig, 1900 (p. 

 165), gives the entire range from lat. 70° W. to 68° E., but Clark, 

 1902, reports this species from Sitka and \\\q Alhatross Alaska Salmon 

 Investigations, 1903, from the Gulf of Georgia, Halibut Bank, Van- 

 couver Island, British Columbia, so that now it can be given as cir- 

 cumpolar. Depth, to 27 fathoms, exceptionally to 45 fathoms.
