8. Peecilichthys saxatilis, Hay, sp. nov. (No. 27,433.) 
In my collection there is a single specimen of another Pwceilichth ys 
that appears to be undescribed. It measures but 12 inches in leneth. 
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 
pectorals. There are about 50 vertical rows of scales and 11 horizontal 
rows, 5 above the lateral line and 6 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 areas 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 equal 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 4 times in the length of the body, the depth 5 
times, and the caudal peduncle 34 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 Boleichthys than a typical Pecilichthys. 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 
spots 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. noy. (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 fin) is contained in the whole length of the body 3§ to 35 times, 
and has a depth one-third its length. The head is small, pointed, and 
contained in the length from 4} to 43 times. Eye in the head 4. Up- 
per jaw protractile. Mouth horizontal, moderate, subinferior, the upper 
jaw overlapping the lower. The depth of the body in its length from 
5 to 54 times +k, 
There are from 50 to 60 vertical rows of scales, and about 12 horizon- 
tal rows between the soft dorsal and anal. The lateral line is found on
