ON SOME NEW SPECIES OF AMERICAN AND AFRICAN FISHES. 



Apogonichthys STELLATUS. 



Scales 7 — 23; radial formula, D. vii, I. 9 ; A. II. 8 ; P. 10. Ventral with elongate rays 

 extending beyond last anal ray. Caudalis rounded. End of maxillary nearly to opposite 

 posterior margin of large orbit. A delicate frontal carina. Greatest depth three times to 

 base of caudalis. End of muzzle truncate, with emargination to receive tubercle of man- 

 dible. Total length 1 inch, 7.5 lines ; head 7.5 lines. 



Reddish-brown, with a series of dark brown spots on the edges of the scales of each 

 row (except that bearing the lateral line), each with a silver centre; head with numerous 

 silver-centred brown spots. Caudal, dorsal, and anal fins dark, with dusky crossbars. 



Two specimens, Mus. Academy, procured by Prof. Horatio C. Wood, Jr., at Nassau, 

 Bahama Islands. 



This is the second species of the genus now known to inhabit American waters. The 

 previously ascertained A. americanus, Castelnau, was obtained at Bahia, but has been 

 discovered by Samuel Powell, member of the Academy, at Newport, R. I. 



Etheostoma macrocephalum, Cope. 



This species is well characterized by its elongate anguilla-like cranium, and small scales. 

 It may be compared with the other species of the genus as follows : 



E. peltatum, Stauffer, Proceedings Academy Nat. Sci., 1864. 



Orbit equal length muzzle ; depth at first ray second dorsal 5.75 in total length to origin 

 caudal. 



Scales 6 — 53 — 8, a few on opcrcle ; those of abdominal series five times size of others. 

 Radii D. XII. 13. A, II. 9. 



E. blennioides, Rafinesque, Kirtland, Bost. Journ. Nat. II., vol. III. 

 Orbit equal length muzzle ; depth to length (as above) 1 : 6.5. 



Scales 8 — 62 — 13-14; some on operculum; those of middle line below twice size of 

 others or wanting. Radii D. XV (XIV) 12 (13). A. II. 9. 



E. macrocephalum, Cope. 



Orbit much less than length muzzle ; depth (as above) 7 times in length to origin caudal.
