I 12 THE PLAGIOSTOMIA. 



Nostrils nearer to eye than to end of snout, valve with a slightly produced and 

 pointed lobe. Mouth large, width nearly twice the length, a short labial fold 

 on the upper jaw at the angle. Teeth moderate, serrated, in 27 rows; upper 

 broader, triangular, slightly oblique, edges hardly indented; lower with broad 

 two-rooted bases and narrow lanceolate cusps that are subcylindrical near the 

 bases and chisel-shaped and serrated at the apices. Median tooth small on both 

 jaws. Eyes small, length of orbit less than half the distance from the nostril, 

 less than half the larger gill openings. Pectoral large, width more than half the 

 length, outer angles blunted, hind margin concave, hind angle reaching below the 

 middle of the dorsal base. Dorsal large, origin above the hind part of the 

 pectoral base, base equal two thirds of its distance from the second dorsal, tip 

 not reaching the ventral origins. Second dorsal above and little forward of the 

 anal. Anal smaller than the second dorsal, hind margin more deeply excavated, 

 base equal the distance from the ventral bases, or from the caudal. Caudal 

 little more than one fourth of the total, pointed, lower lobe produced, about- 

 equal the width of the balance of the fin.

Length of snout less than the width of the internarial space. Nostrils 

 nearly equidistant from the end of the snout and from the mouth. Upper teeth 

 finely serrated, anterior equilateral, rather longer than broad, hinder oblique, 

 concave on the outer edge. Lower teeth in 29 rows, smooth-edged, lanceolate, 

 but with a distal swelling, somewhat as in C. git/ phi*, and with two-rooted bases. 

 Pectoral large, length greater than that from first gill opening to end of snout; 

 length of hind margin only one fourth of that of the front edge. First dorsal 

 origin opposite or close behind the axil of the pectoral. Second dorsal one third 

 as large as the first, larger than the anal. Anal small, origin behind that of the 

 second dorsal. Caudal moderate, length little more than the interdorsal space. 



Uniform brownish, top of first dorsal apparently blackish. 



Total length of type described 8O5, snout to anal 52, snout to dorsal 24j, 

 snout to second dorsal 50, snout to pectoral IS, and length of caudal 20 inches.
