 genic.) 

 cordiformis (small tubercles, possibly photogenic, thickly distributed 



in dorsal integument of body). 

 agassizii (photogenic organs numerous in integument of head, arms, 



tentacle stalks and mantle, both dorsally and ventrally). 

 grimaldii (photogenic organs on dorsal surface of fins, and ventral 



surfaces of head, arms, funnel and mantle). 



flammea (photogenic organs comparatively few; in integument of dorsal 

 surface of fins, and on ventral surfaces of head, ventral arms, funnel 

 and mantle). 



talismani (photogenic organs on ventral aspect of fins). 

 hjorti (photogenic organs on eyes).

Superfamily Cranchioidea. 

 Family CRANCHIID.E. 



Subfamily Cranchiinae. (Series of small photogenic organs on eyes.) 

 Genus CRANCHIA Leach, 1817. 



3 species or forms: hispida, scabra, tenuitentaculata. 

 Genus LIOCRANCHIA Pfeffer, 1884. 



3 species or forms: globulus, reinhardtii, valdivicE. 



1 Chiroteuthis Portieri Joubin, 1916, does not seem strictly referable to the 

 genus in which it is placed, as it is said to possess no luminous organs, while the 

 extreme attenuation and length of the three dorsal pairs of arms are at variance 

 with the well known state of affairs in Chiroteuthis. Hence I would propose the 

 new group Joubiniteuthis, with this species as type.
