the dorsals, but does not reach the second dorsal by about one fourth of the length a 
of the spine; the pectorals reach the middle of the ventral base; the origin of F 
the second dorsal is a little backward from the origins of the ventrals; the m 
claspers are small, only half an inch in length, apparently less mature than the la 
frontal tenaculum, and the ventral tenacula are foreshadowed by a very narrow 
slit in the skin below the bases of the fins. The palatine teeth are figured in 4 
a 
the article on the Chismopnea, pl. 6, fig. 5-6; the longitudinal bars of the tritor 
have fused posteriorly; forward their extremities remain as slender subequal 
points. There is a slender caudal filament, shorter than the head. 
Flanks plain silvery white, a trifle darker above the pectorals and forward 
toward the orbit. The dorsum is darker from the head to the caudal. The fins Waly 
are darker and become lighter toward the hind borders. 
The species named C. heclori by Newton, 1876, was founded on a fossil | 1 
palatine tooth that cannot be distinguished from the teeth of the specimen from jp 
which the present notes are taken. om |

Pectorals rather broad, hardly reaching to the bases of the ventrals. Origin: 
of the first dorsal very little in advance of the origins of the pectorals. Origin’ 
of the second dorsal above the axils of the ventrals. Anal narrow, pointed, 
deeper than the produced lobe on the anterior end of the subcaudal; origin a. 
little backward of the end of the base of the second dorsal. Caudal fins taper= 
ing, slender posteriorly; filament short or absent. Dorsal spine not reachini | 
to the second dorsal by a considerable space. Lateral line with many short 
irregular bends below the space between the first dorsal and the caudal. Hinder 
margins of the ventrals concave. The tritors on the palatine laminae of the 
young are straight bars; later they become reduced in number by fusion into 
a U-shape. On larger specimens the anterior prongs of the tritor become more 
ie 
thickened, and are more nearly equal in length than in C. callorynchus. In)
