Art. XI.—Description of a “ Blind Fish,” from a cave in Ken- 
tucky ; by Jevrrres Wyman, M. D., Member of the Boston So- 
ciety of Natural History. 
Tne specimen from which the following description is drawn, 
was presented to the Boston Society of Natural History by J. G. 
Anthony, Esq. of Cincinnati. It corresponds for the most part 
with the description of the Amblyopsis speleus, described by Dr. 
Dekay in the Fauna of New York, but in some particulars it 
differs. 
The specimen here described was 4,', inches long, and charae- 
terized by a broad vertically compressed head, covered witha 
whitish integument entirely destitute of scales, but on it are seen 
numerous elevations or ridges, most abundant on the lateral por- 
tions ; some of them intersecting each other at right angles, _The 
lower jaw is more prominent than the upper; no appearance of 
eyes; nostrils double, ve anterior ones tubular, the posterior 
nearly circular, about ;'; inch behind the preceding. Both jaws 
are provided with folds of skin, or lips; intermaxillaries and lower 
jaw armed with minute slender and slightly recurved teeth, most 
abundant at a short distance from median line—a group of teeth 
on palatines on each side; also two groups in pharynx above, 
and four below. Upper snasillaries concealed by integuments, 
and destitute of teeth. Intermaxillaries form the borders of mouth - 
above, and extend nearly to its angles. Branchial 2 wie large, 
branchiostegous rays 6 on each sides. 
‘Body covered with circular scales ‘whieh terminate abruptly at 
the posterior limit of the head; the scales are smaller on back 
than on the sides, and are so enveloped in the cuticle as not to 
present free edges. Lateral line occupies the middle of the late- 
ral region, commencing under the anterior extremity of the dorsal 
fin, passes directly backwards, First ray of dorsal, a little poste- 
rior to the middle of body; anal commences a little bebind t the 
dorsal ; abdominals very small. 
Fin rays. Pectoral, 10; dorsal, 10, first very minute ; caudal, 
17 or 18; anal,’9; abdominal, 4, 
Anus very far for waite; about 2; inch behind the anette form- 
ed by the union of branchial membranes,
