Station G9, west of Canary Islands, 29 10' N., 33 36' W., surface, 50-mesh net, 

 plankton, May 29th, 1913. One. 



Station 93, from summit Great King, S.E. by S., 13 miles, surface, 2 4 -mesh net, 

 plankton, July 28th, 1911. One. 



The specimen from Station (>9 has a mantle of 3 '50 mm. in length l>y 2 '25 mm. 

 in breadth, and a head measuring 2 mm. in breadth. The total length is about 

 5 '75 mm. All the arms are developed, but the ventral pair are very small. About 

 four pairs of suckers are present on the third arms, and a few. which appear to have a 

 smooth ring, are placed on the proboscis. The latter has a median line showing where 

 it would eventually have split up to form the tentacles. Three large, round chromato- 

 phores are placed in a transverse line on the dorsal surface of the head, and another 

 occurs near the fork of the- dorsal arms. 



The specimen from Station 93 has a total length of about 7 mm., of which the 

 mantle occupies 4 mm. The tins are very small. The ventral arms are extremely 

 minute, the others being well developed and of about e<jual length, and possessing ten 

 to fourteen suckers each. Seven or eight suckers are present on the proboscis, which 

 is fu^ed throughout its length, the line of future severance being, however, very 

 distinct. Two hirge chromatophores are present on the dorsal surface ot the head 

 below each eve. Both specimens were preserved in formalin.
