100 TIIK CHISMOPNEA (CHIMAEROIDS). 



tho dorsals, but does not reach the second dorsal by about one fourth of the length 

 of the spine; the pectorals reach the middle of the ventral base; the origin of 

 the second dorsal is a little^ backward from the origins of the ventrals; the 

 claspers are small, only half an inch in length, aiii)arently less mature than the 

 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 

 the article on the Chismopnea, pi. (i, fig. 5-(); the longitudinal bars of the tritor 

 have fused posteriorly; forward their extremities remain as slender subeciual 

 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 

 are darker and become lighter toward the hind borders. 



The species named C. hcclori by Newton, 1876, was foumled on a fossil 

 palatine tooth that cannot be distinguished fi'om the teeth of the specimen from 

 which the present notes are taken.

Pectorals rather broad, hardly reaching to the bases of the ventrals. Origin 

 of the first dorsal very little in ailvance of the origins of the pectorals. Origin 

 of the second dorsal above the a,xils 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 reaching 

 to the second dorsal by a considerable^ space. Lateral line with many short 

 irregular bends below the space l^etweiMi the first dorsal and the caudal. Ilintler 

 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 jirongs of the tritor become more 

 thickened, and are more nearly ecjual in length than in C. callorynchus. In
