BULLETIN OF THE BUBEAU OF FISHEBIES 
Chesapeake localities. — (a) Previous records: None. (6) Specimens in collection: All taken 
in the southern sections of the bay, from somewhat north of Cape Charles City, Va., to the mouth 
of the bay. Some were seined in shallow water; others were taken by the Fish Hawk in water 22 
fathoms in depth. Catches were made during the months of July, September, October, and 
December. 
63. NEOETROPUS gen. nov. 
Type Neoetropus macrops sp. nov. 
This genus has the eyes and color on the right side, as in the winter flounders, Pseudopleur- 
o.iectes. However, it has the unsymmetrical ventral fins (the one of the right side being on the ridge 
of the abdomen), the small mouth, and very narrow interorbital of the small flounders, Etropus, 
the members of which have the eyes and color on the left side. It differs from both these genera 
in the elongate body (depth about 3 in length). The teeth are pointed, in a single series, present on 
both sides of the jaws, and apparently wanting on the vomer. The scales are rather large and 
deciduous. 
83. Neoetropus macrops sp. new. 
Type No. 87653, U.S.N.M.; length 55 millimeters; off Smiths Point, Vs. 
Head 4.1; depth 3.2; D. 83; A. 67; scales about 40. Body elongate, strongly compressed; 
dorsal and ventral profiles evenly rounded; head small; snout short, 5.25 in head; eyes large, 
the lower one scarcely in advance of the upper, interorbital space extremely narrow, 3.2 in head; 
mouth very small, oblique; maxillary reaching slightly past anterior margin of eye, 3.5 in head; 
teeth in the jaws pointed, in a single series, not quite as strongly developed on the eyed side as on the 
blind side; vomer apparently toothless; preopercular margin free; gill rakers rather short and blunt, 
placed far apart, six on lower limb of first arch; lateral line without an arch; scales deciduous (all 
lost from the specimen in hand), large (as shown by the marks on the body); origin of dorsal over 
snout, somewhat in advance of eye; dorsal and anal similar, both well separated from the caudal; 
caudal fin somewhat injured in the specimen at hand, apparently round or pointed; ventral fins 
unsymmetrical, the one of the blind side on ridge of abdomen in advance of origin of anal; pectoral 
fins moderately developed on both sides, about 1.9 in head. 
Color of preserved specimen uniform pale, the eyed side being nearly as pale as the blind one. 
A single specimen, 55 millimeters in length, is at hand. We are unable to place this specimen 
in any known genus or species. It has the eyes and color on the right side, as in the winter flounders, 
Pseudopleuronectes. On the other hand, it has the very small mouth, narrow interorbital, and the 
unsymmetrical ventral fins of the small flounders of the genus Etropus. Apparently it differs from 
all the known forms of both genera with which it has characters in common in the elongate body 
and the large eyes. The specimen might be considered an aberrant individual of Etropus, with
