Canadian Arctic Expedition, 1913-18 



Both the North Atlantic, Asiatic, and North Pacific species of Gastropteron 

 are of a reddish colour sprinkled densely with darker red dots. The present 

 form is of a uniform dusky slate colour and of a smaller size than the Pacific 

 species described by Bergh. It is an interesting addition to the sparse list of 

 known species. The spread of the parapodia totals 10 to 15 mm., the length of 

 the body 8 to 11 mm. (in spirits), in the living state it was probably larger. 

 The anterior shield is about one-third the whole length of the body. Like 

 G. pacificum, it lacks a posterior flagellum on the mantle.

Eggs of fish? 



station 7a, b. Latitude 55° 42' N., longitude 136° 20' W., June 25, 1918. Eggs, 

 probably of fish, were found floating on the surface. (F.J.) 



Young of Sipunculoid worm? 



Station 57. 1 fathom in marine plankton, off Cape Smyth, near Point Barrow, 

 Alaska. 



This puzzled our experts, but is left without positive determination, being 

 badly contracted by the preservative.
