specimen from Absecom, N. J., referable to Cottus meridionalis Gir. My 

 specimens all exhibit a more depressed head than is represented by Girard. 

 They differ from the w i 1 8 o n i i in a larger eye and narrow interorbital space, 

 and in their simple pectoral rays ; the caudals are twice furcate. Second 

 dorsal has from 16 to 18 rays. They differ from richardsoniias described, 

 in having the vent considerably nearer the tip of the caudal fin than the end 

 of the muzzle. 

 Dexter, Washington Co., No. 183. Grosse Isle, Prof. Fox. 



Uranidea s p i 1 o t a, sp. nov. 



Entering the section with five ventral rays, and with an elongate body ; and 

 resembling apparently the b a i r d i i, except in its short and anteriorly situated 

 ventral fins. In w i 1 s o n i i the eye is smaller, and frontal width greater ; the 

 pectoral rays are branched, in the present species simple. Inrichardsonii 

 the vent is said to be the median point of the distance from the muzzle to the 

 caudal fin ; here it is much nearer the muzzle. Incognatuswe are informed 

 that the anal fin has a more posterior position. 



The length of the head is contained three times plus one orbital diameter 

 from end of muzzle to base of caudal fin ; said diameter enters 4 times length 

 of head, and is one-third greater than interorbital width. The head is slighty 

 contracted laterally, and not so depressed as in T. a 1 v o r d i i, giving the or- 

 bits less vertical range. One preopercular spine. Insertion of pectorals ob- 

 lique, rays undivided, reaching anus and anterior rays of second dorsal ; ven- 

 trals below middle of pectoral insertion in advance of dorsal, extending half 

 way to vent. Width of isthmus equal from border of (closed) premaxillary to 

 opposite hinder margin of pupil. Dorsal outline low, regularly descending to 

 near end of second dorsal. Greatest depth enters five times from end of muzzle 

 to base of caudal Lateral line disappears between middle and end of caudal. 

 First dorsal low, first ray three-fourths of 2d, 3d and 4th ; anal begins opposite 

 fourth ray of second dorsal. Caudal fin rather small, rays once divided. No 

 trace of palatine teeth. Rays D. VIII. 17, A. 13, V. I. 4, P. 15, Br. VI. Length 

 three inches. 



Above brown, below yellowish, everywhere densely punctulated with darker, 

 except between the veot and anterior to ventral fins. Dorsal, caudal and pec- 

 toral fins barred ; anal yellowish. Base of caudal and dorsal spots blackish ; 

 large lateral round spots of the same color sometimes in seven or fewer cross- 

 bars. 



Several specimens from Grand Rapids, on the Grand River, which flows into 

 Lake Michigan.

 species ; vide the Bull. Mus. Comp. Zool., List of Fishes.

 agreeing with P. Zebra Ag. 



Stizostedium americanu m* C. V. Lucioperca Auct. 

 Nos. 224, 244, 245, 251, 252, from Saginaw Bay. 



Perca flavescens Cuv. 



63. Oakland Co., 229 Saginaw Bay, (presents a monstrous form of skull, 



* The S. cana dense of Smith is identified by Agassiz. " Lake Superior" p., with the ameri- 

 canu m, but it is evident that it is more nearly allied to, if not identical with, the S. aalmoneum 

 Raf.. of the Ohio, a handsome and peculiar fish, slightly resembling an Aspro, as has been remarked. 

 The latter is not tare, an 1 is well described by Rafinesque in Ichth. Ohiensis.
