Fig. 17. Genotype of Macroparalepis {M. affine Ege, from off Madeira, 129 mm. in standard length). 
II of Ege’s Macroparalepis is placed in another 
genus, Stemonosudis. 
DIAGNOSIS: Body compressed and elongate. 
Ventral carina on belly well developed. Head 
and snout long and pointed. Nostrils before 
tip of maxillary. Tip of lower jaw strongly 
elevated. Upper jaw terminating slightly be- 
fore vertical from anterior margin of orbit. 
Angle of gape well before tip of maxillary. 
Supramaxillary short, splinter-like, closely 
bound to maxillary. Teeth on lower jaw long 
and well developed, in 2 rows. Teeth on upper 
jaw well developed antrorse and retrorse ca- 
nines. Vomer toothless. Teeth on palatines 
long, in 2 series anteriorly, 1 row depressible;

A, Anterior part of snout; B, enlarged section of teeth 
on middle of premaxillary; c, anterior lateral-line seg- 
ments; D, gillrakers on first arch; E, dorsal surface of 
tongue. (See explanation of morphological figures in 
text.) 
few short teeth in single row posteriorly. 
Tongue large, moderately forward in mouth. 
Gillrakers not extending forward beyond an- 
terior border of eye or angle of gape. Gill- 
rakers spinous, with 1 row of short fixed 
teeth on small base. Pharyngobranchial teeth 
developed in 1 patch on each side. 
Body and head lacking scales. Lateral-line 
tube large. Membrane over lateral-line modi- 
fied into large scale-like structures, pierced 
above and below by 2 pores on each segment. 
Lateral-line segments partly ossified in double 
concave form as in Lestidum. Greatest height 
of each lateral-line segment variously at front 
or hindmost point. Pectoral fin with 10-11 
rays. Dorsal rays 11-14. Anal rays 24-28. 
I have examined the following species of 
Macroparalepis: M. danae Ege, M. brevis Ege, 
and M. affine Ege. The genus also contains 
Macroparalepis egei Maul. Generic type Ma- 
croparalepis affine Ege. 
Genus Stemonosudis Harry 
Eigs. 19, 20 
Macroparalepis (in part) Ege, 1933: 229. 
Stemonostidis Harry, 1951: 32 (generic type by 
original designation Macroparalepis inter- 
media Ege) . 
DIAGNOSIS: Body slightly compressed and 
very elongate. Ventral carina on belly moder- 
ately developed. Head and snout long and 
pointed. Nostrils behind posterior tip of max- 
illary in Stemonosudis intermedia. (Dr. Ege ex- 
amined the types of Stemonosudis elongata, S. 
gracile, and S. intermedia [his other species of 
this genus are represented by postlarvae only] 
and finds them also with the nostrils behind 
posterior tip of maxillary.) Tip of lower jaw 
not elevated or only slightly so. Upper jaw 
terminating approximately 1 orbital diameter
