Station 43e. Table VII. 



Station 466. Bernard harbour, depth 6 fathoms, ice 5 feet thick, vertical 

 haul with net number 3, from bottom to surface, temperature 29-2° F., Febru- 

 ary 5, 1916. About half a dozen Copepods in all, including: Oithona similis, 

 Oncaea conifera, Idycea furcata, and Dactylopusia signata. 



Station 46^. Dolphin and Union strait, off Chantry island, depth about 

 50 feet, ice 4 feet thick, three vertical hauls, with net number 3, from 33 feet 

 to surface, June 10, 1916. Several Oithona, with several immature Idycea furcata

 Rev. Canon A. M. Norman, F.R.S., Ann. Nat. Hist. (7) XI, 1903, p. 6. 



Station 40c. See Table XIII. 

 Station 40d. Table XIV. 



Station 41fif. Bernard harbour (outer harbour), depth 0-2 fathoms, surface 

 5 minutes, net number 3, August 1, 1915. 



Table XV (Sta. 41?). 



Eurytemora herdmani, one female. 

 Cyclopina schneideri, one male, one female. 

 Harpacticus uniremis, one (injured) . 



Harpacticus superflexus, 48 examples, including several males and one female with 

 ovisac. 



Station 46A. See under Oithona. A female from this station measured 

 0-84 mm., caudal rami shorter than anal segment as 5:6; length of caudal 

 ramus to breadth as 5: 3; interrelations of caudal setae as in C. litoralis Brady.' 

 Anterior antennae 12-jointed, with six terminal subequal small joints; of the 

 proximal joints the fourth is the shortest, the sixth the longest, agreeing with 

 Scott's figures and thus establishing the constancy of these proportions. The 

 mandible, also figured by Scott, has a large B2 (the basal joint of the palp), 

 shaped like an ascidian, carrying at the summit an outwardly curved two-jointed 

 Ri, which is separated by a wide concave interval from the four-jointed Re.
