light organs, then by a somewhat clear stripe, and last by indistinct 

 rows of photophores with scattered ones between. Dorsally the 

 photophores become very scarce and scattered, the large ones not 

 extending to the dorsal sm'face. Along the midline there are indi- 

 cations of pairing of photophores on either side of the gladius rather 

 far apart, but these may be coincidental since some are singly placed. 

 Just anterior of the fin and between the free lobes is a pair of photo- 

 phores on the mantle. About a fourth of the way posterior on the 

 fins is a single pair of photophores, moderately far apart and deeply 

 sunken in the skin. A short distance posteriorly Ues another pair, 

 closer together.
