In addition to the above are the following intrapallial luminous 

 organs: 1. A roundish, swollen, brownish organ on each side of 

 the cavity, a little behind the anus. 2. A very large, elongate- 

 pyriform, bright, silvery organ at the base of each gill, near the 

 middle of the cavity. 3. A bright silvery tubercle, larger than the 

 anal organs, but very much smaller than the branchial, situated 

 behind the viscera in the medio-ventral line nearly at the tip of the 

 body (fig. 4). 



Gladius of simple Enoploteuthid structure, the rhachis free in 

 front and broadest at the apex; thence tapering quite rapidly to a 

 narrow point; wings thin and delicate, sharply angled in front of 

 their middle, where each is about three times as wide as is the stem 

 at the same level; they extend along the posterior two-thirds of the 

 gladius, terminating around the point of the rhachis to form a slight 

 posterior concavity, which is hardly spoon shaped, and is certainly 

 not to be called a cone (figs. 12-14). 



Color in alcohol: mantle brownish white, dotted with pale chro- 

 matophores; head and ventral aspect of the funnel darker, due to 

 the more numerous dark chromatophores; eyes dark slate color, 

 the lenses pearly white; arms and tentacles pale like the mantle. 



Type. — A rather poorly preserved female (?) [S. S. B. 416]. It 

 is minus one tentacle, and a little macerated, but is in good enough 

 condition to be described as above. 



Type Locality. — A beach on Sunday Island, where the single 

 specimen was picked up by Mr. R. S. Bell in 1910.
