The body iu my specimens is deeper, the depth being contained in the 

 length but 4i times or less. The back does not seem to be so broad nor 

 the caudal peduncle so deep. The dark baud that occurs on the caudal 

 peduncle of typical specimens from Georgia is, in these from Mississippi, 

 continued forward along the side to the snout; being, however, slightly 

 broader and less perfectly defined anteriorly. 



I do not, however, think that the differences form sufficient grounds 

 for establishing a new species. My largest specimens have a total length 

 of 3 inches. 



Professor Jordan's specimens were obtained in the upper tributaries 

 of the Alabama Eiver. 



Genus HEMITEEMIA, Cope. 



33. Hemitremia maculata, Hay, sp. nov. (No. 27,438.) 



Body long and slender, slightly elevated at the dorsal, somewhat com- 

 pressed. Depth iu the length 5 times. Head flattened above; snout, 

 looked at from above, obtuse. Mouth small, the maxillary falling con- 

 siderably short of the anterior border of the orbit, terminal, slightly 

 oblique. Teeth 4-4, with grinding surface. 



Head iu the length 4^ times. Eye iu head 3^, about equal to the 

 snout. 



The fin rays are, D. I, 8; A. I, 8. The dorsal begins slightly behind 

 the ventrals. Its length three-fifths, its height four-fifths, of the head. 

 Anal, in length, one-half, in height two-thirds, the head. Caudal pe- 

 duncle one-fourth the length of the body. Dorsal situated nearer to the 

 snout than to base of caudal. 



The i)ores of the lateral line are found on but 8 or 10 scales, anteriorly. 

 Scales 5-38-3. 



This fish is of a straw-color above, with the scales brown edged. There 

 is a faint, narrow dorsal band, and another narrow, dark line running 

 from the vent on each side of the anal fin to the base of the caudal. A 

 leaden band runs along the sides, which is rendered dusky by numerous 

 black puuctulatious on the scales within this band. Besides these mi- 

 nute punctulatious there is on each scale along the center of the band a 

 pair of larger black points. Posteriorly the lateral band ends in a black 

 spot nearly as large as the eye. Snout and top of the head dusky. 



A single specimen, 2^ inches long, and a few young, were obtained at 

 Enterprise. 



Three other species of Hemitremia are recorded. //. vittata, Cope, has 

 teeth 4-5, vvith a black lateral band, and other paler ones above this. 

 H. lieterodon and //. bifrcnata, described by the same author, both have 

 teeth 4-4. They both appear to be less elongated species than the one 

 described above, and neither are mentioned as having the conspicuous 

 caudal spot of JI. maculata^ which is exhibited in all the specimens that 

 I secured. In H. lieterodon the "lateral line is posteriorly imperfect". 

 In H. hifrenata there are 12-13 rows of scales in front of dorsal, and
