mouth and in line with the corners of the mouth. Teeth in 50 rows 

 in each jaw; the lateral teeth flat, the cusps becoming higher and 

 sharper towards the median line. 



Entire under surface of head except just behind mouth covered 

 with small spines, these very dense and forming a heavy shagreen 

 towards tip of snout. Small spines on most of under surface of 

 trunk, but sparse on abdomen behind pectoral girdle, and absent 

 on under surfaces of pectoral and pelvic fins, tail, and ring around 

 vent. Very fine spines on upper surface of rostral cartilage, head, 

 anterior parts of pectoral fins, anterior part of trunk, and anterior 

 third of tail. Upper surface of pectorals with very minute sparse 

 spines, except distally, where they are smooth; pelvics smooth. A 

 median series of larger spines along middle line of back and tail, 

 these large between shoulders, small on middle of back, and larger 

 again on rump and tail. Two lateral rows of irregularly alternating 

 large and small curved spines on tail, and a J shaped row of larger 

 spines bordering orbit anteriorly and medially, these extending back 

 to middle of spiracle. 



Tail 10 inches in length from vent to tip, without lateral cutaneous 

 folds. Dorsal fins of moderate size, separated by a space somewhat 

 less than the length of either one; dorsal row of spines continued 

 between them. 



Color uniform rich brown above, except translucent area at sides 

 of snout. A single conspicuous, eye-like black spot, with well- 

 marked pale yellow border, on pectoral fins, slightly behind broadest 

 point and somewhat nearer middle line of body than edge of pectoral 

 fin. Under surface plain white.

Locality. — Off Galveston jetties, Gulf of Mexico. 



While dredging with a small net in a weedy pool in the coast prairie 

 at Hardin, Liberty County, Texas, a single small specimen of top min- 

 now (Zygonectes Tienslialli), 4 cm. in length, was obtained on January 8, 

 1921. This specimen conforms in every detail with the species as 

 described by Jordan from the San Sebastian River in Southern 

 Florida. The species has not hitherto been recorded outside of 

 Florida, but its occurrence in the coast prairie of eastern Texas 

 would indicate its existence along the entire Gulf coast from Florida 

 to Texas. This specimen has been deposited in the United States 

 National Museum.
