length. Anal well separated from ventral, its origin a little behind 

 pectoral base, front rays free distally and simple, and fin highest near 

 last third its length. Caudal elongate, rounded. Pectoral on left 

 simple, upper median rays longest, its origin little below middle in 

 body depth at that point. Right pectoral shorter, lower median rays 

 longest, fin otherwise similar. Left ventral inserted a trifle behind 

 right ventral, though former a little larger. Vent close to anal origin, 

 presented on lower side. 



Color in alcohol pale sandy-gray on upper side, with scattered 

 inconspicuous areas or patches of slightly darker mottlings. Dorsal 

 and anal pale grayish with dusky blotch basally about every five or 

 six rays, intervening rays and membranes mottled with paler dusky. 

 Caudal grayish with indistinct transverse pale dusky lines. Left 

 pectoral similar. Lower side whitish and transparent, darker varie- 

 gations along dorsal, anal and caudal showing through distally. Peri- 

 toneum white. 



Length 1-j-f inches (47 mm.). 



Type, No. 37,841, A. N. S. P. Corson's Inlet, Cape May County, 

 N. J. September 17, 1910. Dr. Richard J. Phillips. 



Also Nos. 37,842 to 37,850, A. N. S. P., paratypes with same data. 

 These show : Head 3^ to 3f; depth 2^ to 2§; D. 62 to 67; A. 45 to 53 ; 

 scales 37 to 43 in 1. 1. to caudal base; usually 11 scales above 1. 1. at 

 depressed pectoral tip, frequently 10; usually 12 scales below 1. 1. at 

 depressed pectoral tip, frequently 11; snout tip to lower eye front 

 4^- to 5 in head measured from upper jaw tip; lower eye 3 to 3*; 

 maxillary 3 to 3^; left pectoral 1^ to If ; length 1 J to If inches. 



Two examples of Citharichthys arctifrons, kindly loaned by the 

 United States National Museum through Mr. B. A. Bean, differ at 

 once in their larger scales, their longer maxillary and more inclined 

 upper profiles, besides such extent of variation as is shown in the 

 following note. Head 4; depth 21 to 2J; D. 74 or 75; A. 61 or 66; 

 scales in 1. 1. to caudal base 36 to 38 + 2? to 4; about 8 scales (dam- 

 aged) above 1. 1. at greatest depth of body; about 8 scales (damaged) 

 below 1. 1. at greatest depth of body; snout 5 in head measured from 

 upper jaw tip; eye 3f ; maxillary 3; pectoral H; length 3£ to 3| 

 inches. These examples quite agree with Goode and Bean's figure, 1 

 and though in rather poor shape, all the important characters may be 

 made out. They were secured off Martha's Vineyard, Mass., by the 

 schooner Grampus, July 10, 1892. In pointing out the differences
