 of Blue Fish, " Perca antarctica". 



2. St. 32. South Georgia. 1 $ 10 mm. 



3. St. 35. South Georgia. 1 ? with embryos 13 mm. 



4. St. 36. South Georgia. 4 $$ 14-15 mm. (2 ovig., 2 with embryos). 



5. St. 37. South Georgia. 2 ?$ 10 mm. 



6. St. 47. Falklands. 3 ?? 8-10 mm. 



7. St. 66. South-west Atlantic. 1 ? 9 mm. 



8. St. 67. South-west Atlantic. 1 <$ 9 mm., 1 ovig. $ 8 mm., 1 $ with embryos 

 9 mm., 1 juv. 4-5 mm. 



9. St. 71. South-west Atlantic. 1 $ 7-5 mm. 



10. St. 81. South Atlantic. 1 $ 6 mm. 



11. St. 89. South-east Atlantic. 1 $ 7 mm. 



12. St. 116. Bouvet Island. 1 ? with embryos 16 mm. 



13. St. 208. South Shetlands. 2 <$£ 15 mm. 



14. St. 239. South-west Atlantic. 2 $$ 7 and 9 mm. 



15. St. WS 38. South Georgia. 1 $ 16 mm. 



16. St. WS 95. Between Falklands and South America. 10 ovig. $? 8-9 mm. 



Remarks. The material is not very abundant, but there is a well-marked migration 

 from the deeper waters to the upper layers during the night. Examples were caught in 

 day hauls between the depths of 30 m. (8 a.m.; one example) and 45 m. (1 p.m.; four 

 examples), and at 2000 m. During the night all examples were captured between o and 

 55 m., and none below that depth, though at several of the stations hauls from deeper 

 water were made with suitable gear. 



In size SS vary from 9-15 mm. and ovigerous $? from 8-16 mm., in both cases the 

 larger sizes coming from higher latitudes. The SS are much rarer than the ??. Females 

 with ova and embryos were captured in March, April, May and November. 



Only the S<$ (nos. 1, 8, 13) show the green or greenish-blue colour, all the ?$ being 

 (as preserved) yellowish with red or red-brown eyes. 



Distribution. South Atlantic from lat. 30 S; southern Indian and Pacific Oceans.
