Fishes of the Western North Atlantic 403 



with terminal sector between '^ and Vs (28 to 29%) the length of fin, slender, with nar- 

 rowly rounded tip, the lower lobe about 40% as long as upper, its tip narrowly rounded, 

 the re-entrant contour (included by the 2 lobes) well rounded. Distance from origin of 

 caudal to tip of anal about % as long as base of anal. Anal about i.i times as long at base 

 as 2nd dorsal, with slightly more convex anterior and much more deeply concave posterior 

 margins and rounded apex, its free rear corner only about % as long as base, its tip a little 

 anterior to that of 2nd dorsal. Distance from origin of anal to tips of pelvics a little shorter 

 than base of anal. Pelvics about as long at base as anal, and only about as large as latter in 

 area. Pectoral about 0.7 as long as head, and a little less than V2 as broad as long, the outer 

 margin weakly and evenly convex, the distal margin moderately concave, the apex and 

 inner corner both very narrowly rounded. 



Color. Preserved specimens are mouse gray or brownish-gray above, paler below, the 

 fins with darker edges, but without conspicuous black markings. The color of fresh-caught 

 specimens has not been recorded. 



She. The fact that two of the present series still show traces of the umbilical 

 scar suggests a length of about 600 to 650 mm. at birth. But any statement as to the size to 

 which remotus grows would be pure speculation, the only pertinent information being that 

 the type specimen was 1,200 mm. (about 47 inches), and that an immature male from 

 northern Argentina, probably of this species, was 1,030 mm. (about 41 inches) long. 



Developmental Stages. Not known. 



Habits. Nothing whatever is known of the habits of this species. 



Range. Western tropical and subtropical Atlantic. The few records that can be re- 

 ferred to remotus with confidence are for the Antilles (type specimen"'), Rio de Janeiro 

 (see Study Material, p. 400) and probably northern Argentina.
