Greatest width of the head contained about 1 times in its length. 



Dorsal nit slight 1\ nearer the snout than the adipose lin, unusually 

 high, ii^ >]iue 1 ng, as in the species of Jchiltirux. Pectoral spine very 

 strung. about h.-.'ll'as long as the head. Anal lin long, deep, nearly one- 

 third the Icnuih of the body, and composed of - 1 rays. Adipose fin. 

 large, ('amid lin rather short, truncate behind. Jaws equal. Supra- 

 occipital bone hut little free behind. Branchial apertures rather more 

 restricted than usual. Kesembles I. htvitxtris, but with the truncate

IJody elongated, slender, and much compressed. Head usually slen- 

 der and conical. The supraoccipital bone is prolonged backward, and 

 its einarginated apex, in typical species, receives the acuminate anterior 

 point of the second interspinal, thus forming a continuous bony bridge 

 from the head to the dorsal spine. In some species, this connection is 

 more or less imperfect, nsiiiAmitirHN, to which genus all such species 

 have been hitherto referred. Mouth transverse and terminal, the up- 

 per jaw protruding beyond the lower. Teeth subulate, aggregated into 

 a -hort. laterally truncated band on each jaw. Uranehiostegal rays 8 or 

 !'. Dorsal tin situated over the interval between the pectoral and ven- 

 tral tins, higher than long, with one long spine, and usually (I articulated 

 ra\s. Adipose lin pedunculated, over the posterior portion of the anal. 

 Anal lin long, with LM )-:;."> rays; it commences near the vent. Ventral 

 tins each with 1 simple and 7 branched rays. Pectoral lins each with a 

 stout spine, retrorse-senate within, and about 1> branched rays. Caudal 

 lin elon-aled and deeply forked, with the lobes pointed, the upper fre- 

 <|iientl\ the loii-er. Coloration silvery. Fresh waters of North Amer- 

 ica, one species southward to Criialemala;* one in Western Mexico. t
