Hsemulon fremebundum. 



Hcemulon fremebundum Goode & Bean has been redescribed under the 

 name of Diahasis lateralis by Vaillant & Bocourt, Mission Scientifique 

 au Mexique iv, 180, 1883, from Jamaica. 



Sciaena eusifera. 



Gorvina fulgens Vaillant & Bocourt, 1. c, 164, is the prior-named (1882) 

 Sciana ensi/era of Jordan & Gilbert. 



Enneacentrus fulvus ruber. 



The scarlet variety of Enneacentrus fulvus should stand as Enneacen- 

 trus fulvus 7'uber, instead of ouatalibi, as inadvertently given by us on 

 page 402. 



Notropis lirus. 



Notropis alabarnce, described by Jordan & Meek on page 476, proves 

 to be inseparable from Notropis lirus. 



Pcecilichthys jessiae. 



Pcecilichthys sicaini (page 479) is based on an individual indistinguish- 

 able from P. jessice except that the lateral line is complete. A larger 

 series of specimens shows that this " generic " character has here not 

 even specific value. Podcilichthys asprigenis Forbes seems also to vary 

 into P. jessice. 



Boleosoma maculatiim. 



Pcecilichthys beani Jordan (1. c, 479) is based on a somewhat mutilated 

 individual of Boleosoma maculatum. 



The poor condition of the specimen misled me as to its generic rela- 

 tions.

DESCRIPTION OP A ITEW SPECIES OF HYBOGNATHUS (HYBOGNA- 

 THUS HAYI) FROM MISSISSIPPI. 



Br DAVID 8. JORDAN. 



In the Bulletin of the United States Fish Commission, 1882, p. 67, Prof. 

 O. P. Hay has correctly distinguished two species of Hybognathus from 

 specimens collected by him in streams of Mississippi and Western Ten- 

 nessee. For these species he has adopted the names of Hybognathus 

 nuchalis Agassiz and H. argyritis Girard. There is no doubt that the 

 H. nuchalis is correctly identified. The specimens called argyritis by 

 Professor Hay, belong, however, to a species different from the original 

 types of argyritis Girard, with which I have compared them. I regard 

 them as a distinct species, for which I propose the name of Hybognathus 

 hayi. 



Head 4f in length (6f with caudal); depth 4f (4|). D. 8; A. 8.
