Graneledone turqueti, Joubin. 



Eledone Turqueti, Joubin (1-905, p. 29). 



St. 158. 21.1.27. 53° 48' 30" S, 35° 57' 00" W. 401-41101., rock. Large dredge: three young 

 specimens (cj i, ? i, .? sex i) (Brit. Mus. 4 a). 



St. 181. 12. iii. 27. Schollaert Channel, Palmer Archipelago. 160-335 m., mud. Large otter 

 trawl: three aduh specimens (2 <?<?, i ?, two inv.) (Brit. Mus. 4). (?) 



The body is saccular, and the head but Httle narrower than the mantle. The arms are 

 very short (72-64) and the suckers small (11 •5-7-4). The biserial arrangement of the 

 suckers on the fourth arms, noted by Joubin in his first description, is found in one 

 Discovery specimen; but this feature is not of diagnostic value. The web is markedly 

 bilateral, C and D being much deeper than A and E. The web is shallow. In the 

 Discovery specimens it is 20-25 per cent of the arms. In one 'Terra Nova' example 

 it reaches 27 per cent. The head is broad, and the eyes very large. The skin is either 

 quite smooth, or else here and there it shows traces of fine granulations. It is of a more 

 or less uniform light purple colour. 



The mantle aperture is very narrow. The funnel-organ is V V-shaped ; in the larger 

 specimens its limbs seem to be almost as thick as those of charcoti. There are ten to 

 eleven filaments in each demibranch. The hectocotylus is small, about 6 per cent of the 

 hectocotylised arm, that of the only ' Terra Nova ' male being 7 per cent. Unfortunately, 

 this organ is fully developed in none of the Discovery males. In the largest it looks as 

 though it might ultimately grow to resemble that of charcoti. The penis has a large bent 

 receptaculum, as in charcoti (above). 



Remarks. Joubin's species was, as already pointed out, based on small examples.
