Distribution of whale food in the Ross Sea area based on the gatherings of our i-m. stramin nets with additional data from the 'Discovery' and 'Terra Nova'. (1957) States that in the neighbourhood of Marie Byrd Land the East Wind current shows evidence of dividing into two streams, the southern and swifter branch following the edge of the Ross Barrier and Victoria Land coast, the northern branch flowing west-north-west towards Cape Adare and the Balleny Islands where it is joined again by the southern stream. Debenham (1923, end map i) and Hansen (1934, Pis. iv-vii) both show west-north-west diagonal movements across the mouth of the Ross Sea in addition to the current that follows the barrier face. Although no adolescent or adult krill have so far been recorded in the purely shelf water of the Ross Sea area, water, that is, unadulterated by any trace of the warm deep layer, a very few early larvae, undoubtedly belonging to this species, have in fact (p. 301, Figs. 70 and 74) been encountered there, six of the ten stations made by 'Discovery II' in the coldest water of the shelf in January 1936 producing an aggregate of four Second Nauplii, five Metanauplii and six First Calyptopes. The occurrence of these larvae, very small though their numbers be, presents an interesting problem in local distributional dynamics, for in view of the absence of a breeding stock it raises the obvious.
