Pectorals reaching half way across the bases of the ventrals, longer than 
those of C. smythii, little shorter than those of C. capensis. Origin of the 
first dorsal slightly behind the origins of the pectorals. Origin of the second 
| dorsal nearly above the origins of the ventrals; end of the base of the second 
) dorsal somewhat farther forward than the origin of the anal. Subcaudal lobe 
|} produced to a point anteriorly, behind the anal. Interdorsal space about one 
jand one fifth times the length of the base of the first dorsal. Dorsal spine about 
| twice as long as the distance from the spine to the orbit. Hach palatine lamina 
jof the adult specimens at hand has but a single tritor; the fused portion of 
| this is massive and broadly rounded; the prongs in front are rather short and 
thick, the outer one being especially so. 
| Lateral line irregular and waved much like that of C. capensis. The frontal 
ftenaculum, as in all the species of the genus, when viewed from above is sub- 
triangular, broad on the articulation, wide and short in the stem. 
Brownish silvery. A dorsal band of deeper brown is interrupted by the 
ifins, and younger specimens have a dark spot immediately in front of the dorsal 
}spine and a dark area above the orbit. Very young are more spotted.  Varia- 
tions are numerous. 
Off coasts of southern South America.

\Callorynchus antarclicus Ginv., 1870, Cat. 8, p. 351 (part). 
Pectorals appearing long and pointed, reaching the bases of the ventrals 
fnd beyond. Origin of the first dorsal a little forward of the insertions of the 
ipectorals; spine more than twice as long as its distance from the orbit, reaching 
wo thirds of the distance from the origin of the first dorsal to that of the second. 
Origin of the second dorsal little behind a vertical from the origins of the 
entrals. Lateral line decidedly irregular, with short bends. 
On a thirty-three inch specimen the frontal tenaculum is not yet through the 
skin, the dorsal spine is one and one third times the length of the space between
