length, depth 4^; no adipose ej^elid ; preorbital serrate; anal 

 spines 2 ; first soft ray of anal simple, but evidently articulate. 



9. Stromateus medius Peters. 



(Berliner Monatsber., 1869, 707.) 



Type, No. 7073, Berlin Museum, from Mazatlan. In the orig 

 inal description of this species the lateral line is said to be 

 "keeled" on the caudal peduncle. This "keel" is si m pi j^ the 

 ordinar^^ tubing of the lateral line, which is precisely as in the 

 ordinary species of Stromateus. 



Head 3^ in length, depth 1^^^; pectoral 2f in body; dorsal 

 lobe 4^ ; caudal 2|. Dorsal with 42 develojied rays ; anal with 

 32. Length 7i inches, fins distinctly punctulate. 



10. Caranx leucurus Guntber. 



(Proc. Zool. Soc. Lonrl., 1864, 24.) 



T^' pes, two young examples. In our Review of the Carangina? 

 (Proc. U. S. Nat. Mus., 1883, 194) ^ we have placed this species 

 in the group called Urasjns, among the species with broad 

 maxillaries. It should be removed to the group called Hemi- 

 caranx^ among the species with narrow maxillaries, its relations 

 being with G. atrimanus and C. amblyrhynchas. 



Maxillary quite narrow, its length 2| in head, reaching pupil; 

 ej'e not large. Dorsal and anal fins unusually high, but the 

 anterior rays not exserted beyond the rest ; middle rays of dorsal 

 i to f length of head (probably shorter in the adult) ; sheath at 

 base of dorsal little developed ; caudal fin not deeply forked ; 

 pectoral short, 1^ in head (3'oung) ; curve of lateral line 1|^ in 

 straight part, its length 3| times its depth. Teeth slender, rather 

 long, uniserial above and nearly so below. 



^In the paper above quoted (p. 194) we have placed Caranx ruber in the 

 group with the anterior r;iys of soft dorsal and anal not falcate. In speci- 

 mens from Guiana examined by ns, these rays, although very low, are still, 

 properly speaking, falcate, the longest being about 2^ in bead. The species 

 should therefore be removed from the subgenus Uruspis to that of Caranx. 



On page 197. in the same paper, Caranx fasciatus, Cuv. & Val. (ix, p. 

 70), described from a drawing made in Mexico, may be added as an 

 extremely doubtful synonym of Caranx vinclus. 



Caranx cubensis (Pojy) should doubtless be recognized as a distinct 

 species. 



On pages 206 and 20"^ tlie name Chloroscombrus stirurii» occurs. This is 

 a Japuvs for Chlor. orqiieta, the former having been a MSS. name for which 

 the latter was substituted before the publication of the original description.
