tion of ovigerum grades imperceptably into that of a number of 

 species of Careprodus. The genus Careprodus, as at present recog- 

 nized, is probably a polyphyletic one but with our present knowl- 

 edge we certainly are not justified in dividing it. 



Description of type. — Dorsal 43; anal 34; pectoral 34; caudal 10; 

 pyloric coeca 19. Depth 3.7 in length without caudal; head 3.5. 

 Eye 6 in head; disk 2.9. 



Body rather deep at the nape; moderately elongate and com- 

 pressed, tapering gradually to the caudal. Head wide, heavy; 

 width nearly equal to the depth; cheeks swollen; profile concave over 

 eye, rising rapidly at the occiput; occiput slightly swollen; inter- 

 orbital wide; internostril 3.7 in the head. Mouth broad; lateral 

 cleft considerable; angle of mouth reaching vertical from front of 



Figure 52.— Careproctus ovigerum. Teeth from type 



eye; maxillary reaching vertical from posterior margin of eye. Teeth 

 in broad bands, simple, slender; oblique rows widely spaced, about 

 15 in the half of each jaw; inner teeth lanceolate, distinctly recurved; 

 outer teeth much smaller. Snout short, comparatively deep, abrupt, 

 not projecting beyond mouth; upper jaw slightly overlapping lower. 

 Nostril single, apparently in a short tube. Eye moderate, not 

 prominent; pupil large, round. Gill slit wide, 2.4 in the head, extend- 

 ing down in front of eight pectoral ra3^s. The number of pores on 

 the head uncertain as the skin is in poor condition; one supra- 

 branchial pore detected. No prickles. Pyloric coeca 19, on the 

 right side. 



Origin of dorsal above the base of the pectoral fin ; some of the anter- 

 ior rays unsegmented. Caudal broad, connected for two-fifths its 

 length to the anal; the connections between the three vertical fins 

 abrupt, not notched. Pectoral notched; the lower lobe reaching
