Distribution of Genera and Species. 
The family Paralepididae is one of the larg- 
est in the order Iniomi, consisting of 48 
known bathypelagic species. It is world- wide 
in distribution and apparently occurs in large 
numbers in deep water to a depth of about 
4,000 meters. The species are generally wide- 
ranging. Adult specimens seldom fall into the 
hands of ichthyologists, and the majority of the 
adult material has been taken from the stom- 
achs of Alepisaurus, tuna, other larger pelagic 
fishes, and whales. The general form of para- 
lepidids indicates that these are swift-moving 
voracious fishes. Larger specimens have very 
rarely been taken by net and apparently never 
by hook and line. No sexually mature indi-

viduals have been reported, and Dr. Bruun 
informs me that the "Dana” expeditions were 
not able to find or, at least, to determine the 
eggs of this family. It is possible that some 
or most of the species grow to large size and 
that no sexually mature adults have been ob- 
tained. 
The best-known group, the genus Lesti- 
dium, apparently is the only genus whose 
members come to the surface where adults 
may be taken by light at night. The range and 
abundance of the various species of barra- 
cudinas are best understood in the North At- 
lantic and Mediterranean, mainly because of 
the extensive Danish Oceanographical Expe- 
ditions, which obtained the large collections 
reported on by Ege. No examples have bene 
recorded from the South Atlantic (excluding 
the Antarctic), but 20 species are recognized 
in the North Atlantic. Sudis hyalina is appar- 
ently fairly common in the Mediterranean and 
is also known from Madeira. 
About half of the known species of the 
Paralepididae occur in the Pacific Ocean. The 
northernmost form is a species of Notolepis 
taken off the coast of Washington. Eleven 
species of Lestidium and Magnisudis b ary soma 
are variously recorded in the North Pacific 
from off Japan, the Philippine Islands, the 
Hawaiian Islands, Mexico, and California. 
These species of Lestidium (except L. nudum, 
which is apparently known from the Hawaiian 
Islands, Japan, and New Zealand) are known 
only from restricted localities. The barracu- 
dinas have been collected in the more south- 
erly Pacific in the East Indies and off New 
Zealand where five species of Lestidium, Ma- 
croparalepis danae, and five species of Stemono- 
sudis have been recorded. All the East Indian 
species are known only from postlarval or 
juvenile material, except Lestidium nudum. 
Very little material has been collected from 
the Indian Ocean, two of the three recorded 
species being represented by the holotypes 
only. These forms are Lestidium luetkeni from 
the Mozambique Channel, L. jayakari from 
Muscat, Gulf of Oman and Paralepis elongata 
from the Seychelles Islands, Chagos Archi-
