LAMPANYCTUS PUNCTATISSIMUS GUbert. 1913 

 L. punctatissimus Gilbert, 1913 ; Pabb, 1928. 



Material investigated. Type specimen No. 74469, U.S.N.M. 

 Suruga Bay, Japan. 



Adequately and accurately described by Gilbert, 1913, p. 103, but 

 not formerly illustrated. The accompanying diagram has therefore 

 been prepared from the type specimen. 



VLO, upper SAO, Pol and Pre immediately below the lateral 

 line.^^ 



Correctly defined in the previously rendered key. 



Known only from Japan.

 of the minute accessory photophores havei been drawn to show their 



relative PROPORTIONS 



LAMPANYCTUS STILBIUS Gilbert. 1913 

 Lampanyctus stilMus Gilbert, 1913 ; Pabb, 1928 ; Fowler, 1928. 



Material investigated. Type specimen. No. 757768, U.S.N.M. 

 Marquesas Island. 



Very accurately and adequately described and figured by Gilbert 

 1908 (p. 235 and pi. 6). 



Correctly defined in the previously rendered key. 



Recorded only from the type locality. 



LAMPANYCTUS RITTERI Gilbert, 1915 



Lampanyctus ritteri Gilbebt, 1915 ; Parr, 1928. 



Material investigated. Type specimen No. 75807, U.S.N.M. 

 Monterey Bay, California. 



Adequately described and figured by Gilbert, 1915 (p. 318 and fig. 

 3, pi. 15). The presence of a very minute photophore on the shoul- 

 der, mentioned by Gilbert, as a small humeral spot, in addition to a 

 similar small photophore above the posterior corner of the mouth 

 identifies this species with division c (p. 88), instead of division d 



^ " Near the lateral line but not in contact with it."
