The height of the body is one-fourth of the total length (without 

 caudal), the length of the head one-third or a little less than one- 

 third. The origin of the dorsal fin is considerably nearer to the root 

 of the tail than to the extremity of the snout, immediately behind 

 the base of the ventral ; its last ray is in the vertical from the second 

 or third anal ray. The luminous spots appear as mere impressions, 

 and do not sit upon a black globular body ; there are twelve pairs 

 between the throat and the ventral fins, without those of the isthmus.

a. Two inches long. Mediterranean. 



This species is extremely similar to Maurolicus borealis, but has 

 the body comparatively shorter and the head longer. 



/3. Phosphorescent organs slightly prominent, sitting on black globular 

 bodies.

The height of the body is two-ninths of the total length (without 

 caudal), the length of the head rather less than one-third. The 

 origin of the dorsal fin is considerably nearer to the root of the tail 

 than to the extremity of the snout, behind the base of the ventral ; 

 its last ray is in the vertical from the origin of the anal. The lumi- 

 nous spots appear as convex pearls, each sitting on a black globular 

 body ; there are twenty-five pairs between the throat and the ven- 

 tral fiins, those of the isthmus included.

The height of the body is contained five times and a half in the 

 total length (without caudal), tlie length of the head thrice and two- 

 thirds. The origin of the dorsal is considerably nearer to the root 

 of the tail than to the extremity of the snout, behind the base of the 

 ventral ; its last ray is above the fourth or fifth of the anal. The 

 luminous spots appear as convex pearls, each sitting on a black
