Station 48 was 2.5 miles from shore, at a depth of 129.5 feet in 

 what would supposedly be the rubble zone, but here the rubble was 

 covered by a mud deposit. A bottom sampler used through a hole 

 in the ice brought up very little except mud. Animals : Amphipods — • 

 Haploops laevis, i female with 90 peach-colored eggs containing 

 embryos in which eye spots and appendages were visible. Pelecy- 

 pods — Nuculana minuta, 2 (i a dead shell); Astarte montagui, i; 

 Macoma calcarea, i. 



Station 49 was over the rubble zone where mud had been de- 

 posited. At a distance of 3.1 miles from shore, holes were made 

 through 6 inches of ice where a lead had frozen over, and a dredge 

 was lowered to the bottom and pulled by a dog team, but the holes 

 were too close together to get sufficient horizontal pull. The dredge 

 brought up some small stones mixed with the mud. Insofar as is 

 possible, a complete list of the animals taken is given below :
