the Antarctic, 302 mm. in standard length). A, Anterior 
part of snout; B, enlarged section of teeth on meddle

chial teeth developed in 2 patches on each 
side. Branchial membranes do not overlap. 
Body fully scaled. Scales very deciduous, 
rounded or pointed posteriorly, occasionally 
with indentation on anterior margin. The cir- 
culi are continuous for inner 8 rings or more, 
outermost rings run obliquely off the scales 
(see Fig. 11c, and Jensen, 1942: 22, Fig. 6). 
Lateral-line tube large, with at least 1 pore 
above, medially, and below on each segment; 
tube covered by IJ^ rows of scales. Upper 
scale row sometimes notched to receive upper 
pore, as shown in Fig. I4c, or may be pierced 
by pore series as in Paralepis. Lower scale usu- 
ally penetrated by median and lower pores. 
Body scales same size as lateral-line scales. 
Pectoral fin with 11-13 rays. Anal rays 27-34. 
Vertebrae 78-95. 
All three known species of the genus f^oto- 
lepis have been examined. These can be di- 
vided into two subgenera as N. coatsi Dollo 
differs markedly from N. rissoi (Bonaparte) 
and N. coruscans (Jordan and Gilbert) in sev- 
eral characters. 
Subgenus Notolepis Dollo 
Fig. 11c, 13 
DIAGNOSIS: Mandible with 3 series of teeth, 
each row with approximately 35 canines. Pa- 
latine with approximately 50 short fixed teeth 
in single row. Each gillraker on ceratobran-

chial of first arch with approximately 30 short, ‘ 
fixed, needle-like teeth. Apparently, each 
lateral-line segment with large median-pore 
at posterior margin and tiny pore above and 
below near anterior margin. Anal rays 27-29. 
This subgenus is monotypic, containing 
only Notolepis coatsi from the Antarctic.

Arctozenus (in part) Jordan and Evermann,

DIAGNOSIS: Mandible with 2 series of teeth, 
totaling approximately 25 canines. Palatine 
anteriorly with long widely spaced depressible 
canines accompanied by short fixed teeth, 
posteriorly with 30 or fewer short fixed can- 
ines in single row. Each gillraker on cerato- 
branchial of first arch with approximately 15 
short fixed spine-like teeth. Each lateral-line 
segment with 1 large pore above and another 
below at posterior margin, with pair of minute
