704 LÖNNBERG, TWO CEPHÅLOPODS FROM TENERIFFE. 



together form the connective apparatus. The whole lengtli of 

 this is about 30—35 mm. The three distal members of this 

 apparatus sit close together, only 1 — 3 mm. apart, but the five 

 proximal ones are wider (4 — 6 mm.) apart. The diameter of the 

 pulvilli is 1 — 1,5 mm. 



The colour of the animal is reddish brown, lighter below. 

 Even the tentacles are provided with chromatophores.

This Ommatostreplies is easily recognized and is distinguished 

 from all other forms of the same genus by the above given 

 diagnosis. It is of course most closely aliied to O. hartrami which 

 has the same number of members in the connective apparatus, 

 but these seera to sit closer together in the main form. More- 

 over, the typical O. bartrami has the brachial formula difFerent, 

 a smaller number of plicse in the siphonal fossa, smaller fins 

 and shorter tentacles. O. oualaniensis , too, has a similar con- 

 nective apparatus but a different brachial formula, arms com- 

 paratively raore webbed, much shorter tentacles, much smaller
