Some of these have the mouth subinferior, the barbels eonspicnous, 

 forming a tuft at the chin ; the dorsal spines 10 and the caudal double- 

 truncate ; the gill-rakers short. The diagnosis should be amended 

 accordingly. 



Page 570. Instead of Scicvnu punctata read: 



§96. S. chrysura (Lac.) J. & G. 



(Diplerodon chrysiinis L.-.xcopi'di' iii, G4, 1802.) 



There are two species called Perea jyunctata in the Sy sterna Naturae, 

 and the second of these should be suppressed.

 908. M. littoralis (Holbr.) Gill.— 6'm»-/ Uldtinf/. 



Grayish silvery, nearly plain, without traces of bars; pectorals, ven- 

 trals, and anal pale, with a few black dots; caudal tipped with blackish ; 

 lining of o])ercle pale. Body rather elongate, the caudal peduncle very 

 slender; snout hluntish, 3 in head, projecting beyond premaxillary for 

 about one-sixth its length ; maxillary reaching about to front of eye ; 

 ])Osterior nostril lanceolate; outer teeth little enlarged, very much 

 smaller than in M. alburnus. Gill-rakers small, but developed; lower 

 lobe of caudal longest. Scales on breast very small, irregular. Head

 and Gulf coast. Jf. utululatus'm closely related to this si^ecies. 



M. alburnus is darker in color, usually with traces of dusky bars; 

 pectorals blackish ; lining of opercle black. Snout sharp, 3f in head ; 

 snout much projecting (one-third its length). Outer teeth of upper Jaw 

 very large; posterior nostril ovate; gill-rakers tubercular, almost obso- 

 lete ; maxillary about reaching middle of eye. Scales on breast large, 

 regidarly placed. Head 3^ ; dei^th 4^. D. X-I, 24 ; A. I, 7 ; scales G- 

 54-11. 



Page 578. Menticirrus undulatus has the outer teeth of the upper Jaw 

 not greatly enlarged and should have been ])laced rather under ^f instead 

 of aa. Umbrina elongata (ithr., from the I'acific coast of tropical America, 

 is a diHerent species. The latter name should be erased from the synon- 

 ymy of M. undulatus. 



Page 578. The teeth in Larimus are mostly in single series. The 

 gunus ^^ Monosira^^ Poey (Anal. Soc. Esp. Ilist.'Xat., x, 320, 1881), is 

 identical with Lariinus. 



V-cV^ii 57!). The genus Atractoscion should be suppressed. Our species 

 may stand as 012, (Jynoscion nobile (Ay res) J. & (1.
