8. Pcecilichthys saxatilis, Hay, sp. uov. (No. 27,433.) 



Ill my collection there is a single specimen of another Pcecilichthys 

 that appears to be nndescribetl. It measures but If inches in length. 

 The lateral line is incomplete, but extends as far back as the posterior 

 rays of the soft dorsal, being found on 35 scales and not arched over the 

 l)ectorals. There are about 50 vertical rows of scales and 11 horizontal 

 rows, 5 above the lateral lino and (I below. 



The opercula have a few large scales, but the cheeks are naked. The 

 breast and throat are bare. 



The dorsal and anal fin-rays are as follows : D. XI, 10 ; A. II, 7. The 

 spinous dorsal equals the head in its length, and is one-half as high as 

 long. 



The soft dorsal is two-thirds as long as the head, and as high as long. 

 The dorsals are separated by a space e(iual to one-half the head. The 

 anal, in height and length, is equal to nearly one-half the length of the 

 head. 



The head is contained 1 times in the length of the body, the depth 5 

 times, and the caudal peduncle 'Sh times. The head is narrow and 

 pointed ; the profile descends in a gradual curve. The mouth is hori- 

 zontal, terminal, and large, the maxillary extending back to a vertical 

 from the anterior edge of the pupil. The eye is equal to the snout, and 

 is contained in the head 4 times. Upper jaw non-protractile. 



In color the specimen in my possession rather resembles a Boleosoma 

 or a Bokichthys than a typical Pcecilichthys. Above, the ground color is 

 yellowish olive, below pale. On the dorsal region are about six square 

 brown spots. Along the sides there are about eight somewhat W-shaped 

 S])ots of the same color, between which and the dorsal blotches are many 

 specks of brown arranged in zigzag lines. A black streak before the eye 

 and another below it. Opercle mostly black. An enlarged black hu- 

 meral scale on each side. All the fins, except the anal, more or less 

 barred with dusky. 



Found at Enterprise in a rocky and sandy stream flowing into the 

 Chickasawha. 



Genus VAILLANTIA, Jordan. 



9. Vaillantia chlorosoma, Hay, sp. udv. (No. 27,428.) 



Body slender, compressed, and the dorsal region much arched. At 

 the vent the body is suddenly contracted into the long and slender cau- 

 dal peduncle, which (measured from the posterior anal ray to base of 

 caudal tin) is contained in the whole length of the body 3^ to 3^ times, 

 and has a depth one-third its length. The head is small, pointed, and 

 contained in the length from 4i to If times. Eye in the head 4. Up- 

 per jaw protractde. Mouth horizontal, moderate, subiuferior, the upper 

 jaw overlapping tlie lower. Tlie depth of the body in its length from 

 5 to 5.] times 



There are from 50 to GO \ ertical rows of scales, and about 12 horizon- 

 tal rows between the soft dorsal and anal. The lateral line is found on
