ICHTHYOLOGICAL COLLECTIONS OF THE ALBATROSS. 459 



Dorsal beginning vertically above base of pectorals; the second spine extremely 

 long and slender, smooth basally, the terminal half rather strongly toothed. It 

 becomes very slender toward the tip, and terminates in a long membranons fila- 

 ment. In one specimen it exceeds length of head, in the others it equals five-sixths 

 that length. Length of base of first dorsal equaling one-third length of head. 

 Interspace between dorsals short, two-fifths to three-fourtljs length of snout. Pec- 

 torals very long and slender, equaling the head without the snout. Outer ventral 

 rays very long and filamentous, equaling length of head. Vent immediately in 

 advance of anal origin. Scales rather thin, those on back and sides with about five 

 diverging ridges, each of which bears a number of short rigid spinules directed very 

 obliquely backward, the posterior projecting but little beyond the margin of the 

 scale. Eight or nine scales in an oblique series between the middle of first dorsal 

 and the lateral line. 



Dorsal ii, 12 to 14; pectoral 20 to 22; ventral 9 or 10. 



Dark brown, the fins, gill-membranes, lips, nostrils, and under side of snout black. 

 Anterior part of mouth and lining of gill-cavity purple. Peritoneum blackish 

 brown.
