Specimen M *+?° consists of fragments of a very large example. 
The siphon, which has a A-shaped organ, measures I5 mm. in 
length and 6 mm. at the apex which is flattened. None of the 
arms shows any sign of a hectocotylus, and as they are all detached 
from the body their order cannot be ascertained. The shortest 
measures 100 mm. in length and possesses thirteen suckers 
arranged singly, but unequal gaps and fibres of muscle show that 
many suckers are missing. ‘The six largest are placed on the 
distal half and measure nearly 5mm. in diameter by 5 mm. in 
height ; the most distal sucker measures 1°25 mm. in diameter and 
the fina! 8 mm. of arm is devoid of suckers. All are shaped as 
described by Hoyle for FE. diaphana and have a quadrangular 
opening caused by four rounded lips folded towards each other as 
in Berry’s figure of a single sucker of E. heathi, Berry (1912, pl. 
33, fig. 3). The longest arm measures 171 mm. and has eleven 
suckers, the largest measuring 7mm. in diameter at the base. 
The other arms measure 166 mm., 167 mm., 135 mm., 130 mm., 
125 mm.,and 110 mm. in length. The mantle is denuded of 
epidermis, but the arms are pale buff with brown spots, and such 
of the animal as is present possesses the delicate hyaline consis- 

Less tip.
