Japan. Gilbert’s description was based on an example 67 mm. long 
m the ^arnegie Museum. It is figured with the suprapeetoral photophore 
near upper 2/5 in space between pectoral fin origin and lateral line, 
though the description says "its distance from lateral line but half its 
distance from pectoral base." In most every other respect the arrangement 
of the photophores is greatly like those of his figure of Diaphus 
anteorbltails, only the interspaces between the median and uppermost 
supraanal and the last anteroanal and mediolateral slightly greater in 
Dia^us aagamiensis. The chief differences would seem to be the greater 
development of the antorbital luminous organs of Diaphus enteorbitalis.

while in Diaphus sagamiensis they seem to be less extensive their general 
appearance is similar. 
Other items supplied by Gilbert’s figure and description are due to 
its larger size and evidently better preservation. Thus the ventral 
axillary scale is shown nearly 1/3 ventral fin length and caudal fin base 
scaly.
