AUSTRALASIAN ANTARCTIC EXPEDITION. 
Genus Eulalia Savigny. 
Eulalia charcoti Gravier. 
Gravier (1911), p. 57, pi. I, figs. 14-16 ; pi. II, figs. 17, 18. 
Eulalia charcoti lives in comparatively deep water, our specimens coming from 
depths of 110-318 fathoms, and Gravier’s from 210 fathoms (approx.). 
The preserved specimens have a dark greenish-blue body with brownish-green 
cirri ; the body is highly iridescent, and in one individual the effect produced is a bronzy 
green colour. 
Two of them have a dark blue band along the middle third of the dorsum, with 
a green iridescence ; the lateral thirds being russet brown, and the cirri olive green. 
The whole effect is very beautiful. Gravier states that in life the worm is “ emerald 
green with blue iridescence.” There is but little to add to his account. 
The longest of our specimens measures 150 mm. by 6 mm. across the body, 
which is larger than Gravier’s largest. The longest of the tentacular cirri, belonging 
to the second segment, is 8 nun., and reaches to the 23rd segment, the next one is only 
5 mm. long, and reaches to the 15th ; the others are about half the length of the latter. 
These measurements are taken from a specimen 95 mm. long, with a diameter of body 
5 mm. 
The pharynx is everted in one individual, and shows the characteristic arrange¬ 
ment of the papillae, unusual in the genus, namely, six longitudinal rows of curved 
brown-edged papillae, united basally by a broad continuous band of smaller rounded 
ones, and distally by a girdle of similar papillae. There are about 50 small close-set 
papillae at the entrance—an unusually large number.
