17. LEPIOPOMUS ISCHYRUS, Jordan & Nelson, sp. nov. 



Ichthelis aquilmsis, Nelson, Bull. Ills. Mus. Nat. Hist, i, 1876, 37 (not Fomotia aquilensia 

 Grd.). 



Numerous young specimens purporting to be types of Baird and 

 Girard's P. aquilensis are in the National Museum, Two species seem 

 to be represented among them, the one a Xenotis, the other a Lepiopo- 

 mus. Neither of them is identical with 1. aquilensis Nelson, and as the 

 latter species seems not to have been hitherto named, the above appel- 

 lation is i^roposed for it. 



18. LEPIOPOMUS APIATUS, Cope. 

 Lepomis apiatus, Cope, Proc. Am. Pbilos. Soc. 1877. (In press.) 



This is a large species related to L. macrochirus Eaf., and more 

 closely to L. elongatus (Holbr.), but stouter built than either, and with 

 marked peculiarities of coloration. 



Body deep, compressed, the form somewhat as in Enpomotis aureus. 

 Profile rising rapidly from the snout; the nape swollen, forming an 

 angle above the eye ; caudal peduncle deep, not especially elongated. 

 Mouth moderate; maxillary reaching to just past anterior margin of 

 the eye, the lower jaw projecting somewhat when the mouth is closed. 

 A small patch of teeth on the anterior edge of the palatines (some- 

 times obsolete); eye large; opercular flap short and deep, considera- 

 bly shorter than the eye. 



Dorsal spines high, those in the middle highest, so that a slight 

 notch is made at the beginning of the soft rays ; the soft parts of the 

 vertical fins are largely scaly. Pectoral fins moderate, barely reaching 

 anal. Anal spines strong, the soft rays high. Longest dorsal spino 

 nearly equal to the distance from the snout to the posterior edge of 

 the orbit. 



Head 3 in length, the depth IJ ; eye 4 in head, larger than the oper- 

 cular flap, which is short and deep. 



Gill-rakers rather long, stiff, pretty strongly dentate. 



Fin-rays :— D. X, 11. A. Ill, 10. 



Scales 6-40-13, those on the cheek large, in about seven rows. 



Coloration somewhat altered by the alcohol. There are no spots on 

 the fins, and there are no traces of blue lines on the cheeks. The most 

 marked feature of coloration is the presence on various parts of the 

 body of little dark brown or black spots, chiefly at the base of the
