In addition there was an Ectinosoma, a Pseudobradya and an Acartia. The 



presence at this station of Limnocalanus is of particular interest, as will be detailed 



more fully below. One C. finmarchicus 9 measured 4.25 mm., another 4.5 mm.

Station 29e: 70° 3' N., 141° W., depth 25 fathoms, April 2, 1914. Three 

 vertical hauls with net No. 3, from 0-20 fathoms, through crack in ice, yielded 

 one C. finmarchicus 9 and two or three immature male Pseudocalanus. 



Station 29^^: 70° 20' N., 140° 30' W., depth 150 fathoms, April 6, 1914. 

 Several vertical hauls were made, at various depths with plankton net number 

 5^ through cracks in the ice. The captures comprised C. finmarchicus, young 

 and adult, including a female of 5-5 mm., and a male of 4-5 mm., in company 

 with Calanus hyperhoreus, Pseudocalanus elongatus, Euchaeta norvegica (see 

 below), Metridia longa and Oithona similis. 



Station 41s: Bernard harbour (inner harbour). Dolphin and Union strait,'

The absence of adult Calanus is to be noticed. One Eurytemora carried 

 an ovisac. The C. hyperhoreus V (the stage preceding maturity) measured 

 6 mm. in length and the fifth foot had 15 coxal teeth. One C. finmarchicus V 

 of 4 mm., had 28 coxal teeth at the base of the fifth foot. At stage 1 there are 



' Vertical net, 12 inches across mouth, end open 3 inches wide, with brass bucket and silk-net bottom; 

 length 3i feet, the upper half made of canvas.
