 I he bulb. Thi' rim of the outer lip is also strengthened by a narrow cartilaginous belt, 

 \\hich expands conspicuously on the ventral surface of the bulb. A female, with 

 mantle-length of 25 mm., possesses nidameutal glands measuring about 9 mm. by 

 (> mm. A very large number of eggs, all with their surface adorned with a graceful 

 honeycomb-pattern, are present, the largest measuring 4 mm. by 3 '50 mm.

These little creatures seem to be obviously the same larva as that figured in so 

 many stages by Chun ('10.pl. 12. figs. 3-15, pi. 13, figs. 9-12), and which he was 

 able to trace, by numerous gradations in size from newly-hatched specimens to full- 

 grown examples, to / '. ij'ntrdi. All have the large eyes and the characteristic bend 

 near the base of the tentacles, which latter terminate in little round clubs. The 

 outline of the gladius is very distinct in all. The arm-suckers are placed two in a 

 row. except that the most proximal is usually placed singly. None has tiny 

 chromatophores on the mantle, but this may be due to abrasion of the epidermis. 

 A few large golden-brown or reddish chromatophores are present on the head, and 

 a single large one is invariably placed on each tentacle near the club, and a few 

 smaller ones are scattered on the arms. 



The largest specimen (Station 80) has a mantle-length of 4 '50 mm. Beautiful 

 blue, violet, and pink luminous organs shimmer on the ventral surface of each eye, 

 the organ 10 (Chun, '10, pi. XIV, fig. G, numeration of eye-organs) is present on both. 

 the right eye has also 9, 1. and 3 ; the left eye seems to have 3, 5, 7. and 8 as well as 

 10. The third and fourth arms have wide membranes. The tentacles have each a 

 bunch of about twenty suckers with apparently smooth ring: no hooks present. The
