Depth of body 32 to 41 in the length, length of head 3 to 32. Snout as long as or shorter than eye, the

short tube attached to the basal part of the anterior anal rays. Pectoral 2 the length of head. Caudal 
subtruncate. Sides with a series of blackish vertical bars, which are broader and less sharply defined in

Dr. Meek (Publ. Columbian Mus., Zool. v. 1904, p. 107) describes this species as 
having 40 to 46 scales in a longitudinal series. Specimens which I have examined, 
and which certainly belong to & grandis as described and figured by Girard, have 
36 to 38 scales in a longitudinal series. In females of this species the length of the 
tube attached to the anal fin is about } the depth of the fin, in F. heteroclitus about 2.
