52: AUSTRALASIAN ANTARCTIC EXPEDITION. 



Genus Eulalia Savigny. 



EuLALiA CHARCOTi Gmvier. 



Gravier (1911), p. 57, pi. I, figs. lJr-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 mm., 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 papilla^, 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.
