Teeth ^^-^jEjotI^is"^^"' "PP^'"S triangular, increasingly oblique toward corners of 

 mouth, their outer edges more or less notched, with some toward center of jaw notched 

 on both sides, the edges serrate, very finely toward tips and somewhat more coarsely 

 toward bases, but very much worn;'* lower teeth smaller, more slender and more nearly 

 erect, symmetrical, with narrow cusps and broad bases, their margins smooth toward bases 

 and slightly wavy toward tips but not definitely serrate; 2 or 3 minute teeth at symphysis 

 in both jaws. 



Origin of ist dorsal over, or slightly posterior to, inner corner of pectoral, its vertical 

 height about Vs as great as length of head to 5th gill opening, its apex rounded, its rear 

 margin deeply concave basally, its free rear tip very slender and about % is long as its base. 

 Origin of 2nd dorsal about over origin of anal, its vertical height only about V4 to Vs as 

 great as that of ist dorsal, its posterior margin only weakly concave, its free rear tip very 

 slender and greatly elongate, it being about 2 V2 times as long as the vertical height of the 

 fin, or I V2 times as long as its base, and extending about % the distance from rear end of 

 base toward precaudal pit. Caudal a little more than V4 of total length, its terminal sector a 

 little less than Vs total length of fin, slender, with concave lower margin and narrowly 

 rounded tip, the lower lobe (expanded lower anterior corner) about V2 as long as upper, 

 with subacute tip and moderately convex anterior margin, the re-entrant corner included 

 between the two lobes subrectangular (rounded in falclformis). Anal a little longer at 

 base than 2nd dorsal, with much more deeply incised posterior and more broadly rounded 

 posterior margins, its free rear tip slender, a little longer than its base, about i V2 times its 

 vertical height, and terminating about under tip of 2nd dorsal. Distance from origin of 

 anal to tips of pelvics nearly or quite twice as long as base of anal. Pelvics about i ^2 times as 

 long at base as anal, with weakly concave distal margins, their origin about midway 

 between origins of ist and 2nd dorsals. Pectoral nearly or quite as long as head or about 

 2V2 times as long as vertical height of ist dorsal, a little less than V2 as broad as long, the 

 outer margin moderately convex, distal margin deeply concave basally, the apex and 

 inner corner narrowly rounded. 



Color. The type specimen was shiny black above when fresh caught, dirty white 

 below; the tips of the pectorals somewhat dusky below; the Cuban specimen was dark 

 gray above in life. 



Size. This is one of the larger members of the genus; all the specimens so far 

 reported have been between about eight and ten feet long. 



Developmental Stages. Embryos of this species have been reported but not described. 



Habits. Little is known of the habits of this newly described species except that ofiF 

 Salerno, Florida, it is usually taken only where lines are set at a depth of 100 feet or 

 more. While one large individual was taken on the reef near Metacumbe Key in about 

 45 feet of water, it was so thin as to suggest that its excursion into relatively shoal water 

 was abnormal. 



16. Those of the Cochinos Bay specimen are more definitely notched than those of the type specimen, and with 

 coarser basal serrations.
