5. ExoccettiS rufipinnis Cuvie'- & Valenciennes. 



(Hist. Nat., Poiss., xix, 99.) 



T3pe from Payta, Peru; an adult specimen, in good condition. 



Head 4t in length to base of caudal ; depth 5§ ; lower lobe of 

 caudal 3^; eye 3J in head. Ventrals 3^ in body. D. 11; A. 

 1, 11. Insertion of anal scarcely behind that of dorsal, its base 

 but little shorter ; both fins low, the longest ray of dorsal little 

 more than half the base of the fin. Pectorals reaching base of 

 caudal; ventrals to just behind last ray of anal. Third ra^' of 

 pectoral branched, the fourth longest. Pectorals and A'entrals 

 centrally dusky, without distinct markings. 



This species is probabW identical with E. doivi Gill (Proc. 

 Ac. Nat. Sci. Phila., 1863, 161), from Panama, a species not now 

 represented in the National Museum. 



6. Tylosurus hians (Cuv. & Val ) Jor. & Gilb. 



(Belone Mans Cuv. & Yal., xviii, 432.) 

 In the type of this species the insertion of the ventrals is 

 about midway between the base of the caudal and the middle of 

 the arch of the base of the upper jaw, or slightly nearer tip of 

 pectoral than front of anal. According to Valenciennes, " elle 

 est attache un pen avant le milieu de la longueur totale." This 

 statement is not quite correct. On account of this discrepancy. 

 Poey has described the Cuban fish as distinct, under the name of 

 Belone macidata (Mem. Cuba, ii, 290), the ventral fin 1)eing 

 inserted behind the middle of the length of the body. It is not 

 likely that an^^ real difference exists. The specimens found along 

 our Atlantic coast agree ver}^ well with Poey"s description. 



7. Querimana harengus (GUnther) .Tor. & Gilb. 



[Myxus harengus Giintlier, lit, 467.) 

 The tj\)GHO^ Myxus harengus have but two anal spines, instead 

 of three, as stated in the original description. Specimens of this 

 species from Zorritas, Peru, are in the museum of Yale Colle<re. 

 In tiie National Museum are specimens from Panama, Mazatlan, 

 and Charleston, S. C. 



8. Qaerimana cihilabis (Cuv. k Val.) Jor. 



{Mvg'l ciliilabis, C. & V. xi, 151.) 



The types of Mugil ciliilabis, from Lima, belong also to the 



genus Querimana. The species is very close to Q. harengus 



differing in rather stronger dentition, stiffened cilia, or teeth being 



present in both jaws, rather strongest in the upper. Head 3? in
