134 “TERRA NOVA” EXPEDITION. 
terminal position before the dorsal and anal rays develop ; of these the posterior rays 
appear first, at any rate in Pleuragramma. 
Of the forms identified the larvae of the Nototheniinae differ from the rest in the 
small size of the yolk-sac. Of those with a large yolk-sac Artedidraco is distinguished 
from Gymnodraco by the short tail, whilst the Chaenichthyidae differ from both in the 
wide mouth and the early development of the pelvic fins.* 
Except Pleuragramma artarcticum larval and post-larval Notothenioids have only 
been taken quite near the coast. There is some evidence that the young of Notothenia 
macrocephala, a widely distributed species, may be pelagic. 
II—FISHES FROM THE TROPICAL AND SOUTH 
TEMPERATE ZONES. 
Larval and post-larval fishes were taken, by means of plankton nets and the 
young fish trawl, at or near the surface in the following areas :— 
(1) North of New Zealand and round the Three Kings Islands. Stations 85-142. 
July to September, 1911. 
(2) Melbourne Harbour. Station 161. October, 1910. 
(3) Temperate South Atlantic, about 200 miles from the coast of Uruguay. 
Station 311. April, 1913. 
(4) Off Rio de Janeiro. Stations 39-40. — April, 1913. 
(5) Western Tropical Atlantic, south of the Equator. Stations 43-57. 
May, 1913. 
(6) Atlantic, south of the Canaries. Stations 16-17. June, 1910. 
(7) Atlantic, south of the Azores and west of the Canaries. Stations 68-69. 
May, 1913. 
The nature of the collections made in these areas is shown by the following
