6. CUCUMARIA CHRONHJELMI Theel, i886. 



June 27, 1903. — One specimen; Quarantine Station, Dock Port 

 Townsend, Washington. June 30. — One specimen; Station 4209 ; lat. 

 48° 8' 55" N., long. 122- 41-' 10" W.; 24 to 25 fathoms; bottom, 

 temperature 50.3°, rocky, coarse sand, shells. 



The deficiency in figures of the spicules in Theel's original descrip- 

 tion is supplied by Clark, 1901. In the tentacles, the supporting rods 

 vary in form to irregular plates, and either the rods or plates may 

 bear spines, a fact not brought out by Clark's description, or figure.

7. CUCUMARIA VEGiE Theel, 1886. 



August 24, 19(»3. — One specimen from Shakan Beach, southeast 

 Alaska. 



This specimen, in general agreement with the description of Theel, 

 1886, has the following measurements in centimeters: Length, 2.7; 

 dorso-ventral diameter, 1.2; transverse diameter, 1.1. The color of 

 the specimen in alcohol is slate-black around the mouth and anus as 

 well as in the dorsal region, shading- laterally to mixed light gray and 

 smoke gray on the ventral surface. The tentacles are black and the 

 ends of the pedicels cream color. Usuall}^, in larger individuals 

 especially, the color is seal-brown dorsally shading to chocolate ven- 

 trally. There are many examples of this species in the collections of 

 the United States National Museum which I have at hand, and, as 

 Clark, 1902, notes, this species is very abundant in the North Pacific.
