17. LEPIOPOMUS ISCHYRUS, Jordan & Nelson, sp. nov. 
Ichthelis aquilensis, NELSON, Bull. Ills. Mus. Nat. Hist. i, 1876, 37 (not Pomotis 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 J. aquilensis Nelson, and as the 
latter species seems not to have been hitherto named, the above appel- 
lation is proposed for it. 
18. LEPIOPOMUS APIATUS, Cope. 
Lepomis apiatus, Copr, Proc. Am. Philos. Soc. 1877. (In press.) 
This is a large species related to LZ. macrochirus Raf., and more 
closely to JL. elongatus (Holbr.), but stouter built than either, and with 
marked peculiarities of coloration. 
Body deep, compressed, the form somewhat as in Hupomotis 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 spine 
nearly equal to the distance from the snout to the posterior edge of 
the orbit. 
Head 3 in length, the depth 13; eye 4 in head, larger than the oper- 
cular flap, which is short and deep. 
Gill-rakers rather long, stiff, pretty strongly dentate. 
cin-rays:—_D, X, 11. A. tit 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
