Scabt/s radians, " Cuv. Val." Gunther Cat., B. Mus., iv., 211. 



Several specimens which agree with Giinther's description, but not with any of Prof. Poey's.

SCAEUS TTOIM.OMYSTAX, Cope 8p. nOV. 



This species agrees with the description given by Gunther of what he considers to be the young of the last species. 

 It is clearly not the young of 8. radians, nor of any of the species described by Gunther or Poey. It is nearly allied 

 to the 8. lachrymosus and 8. atomarius of Poey, (Repert. Pis., etc., Cuba. II., 848,) in having prominent divergent 

 acute teeth external to the confluent series of the upper jaw. This character is evanescent in 8. chrysopterus and 

 8, abildgaardii as Indicated by our specimens, but would Indicate another genus were it, constant. Our specimens of 

 8. radiam (above) are of the same size as those of the present species, and display no trace of external teeth, live of 

 the former being compared with the latter. The 8. radians display the caudal fln openly emarginate, the A hoplo- 

 mi/sla.r rounded. In (lie former, there are obscure cross-bauds with scattered red scales, in the hitter a- broad longi- 

 tudinal band, with red below it. This band extends from the orbit to near the caudal (in including two and two half 

 TOWS of Scales. There are four equidistant pale spots in its course, a, silvery band round the Chin. Three brown 

 spots on the dorsal fin; other parts of that and the caudal punctate with white and brownish, a row of small white 

 dots on pectoral, round the basis. Anal tin with white; variations and three vertical brown spots, four in some,— 

 obscure in others. A. very faint spot at the base of the pectoral, wanting in sum e ; it is quite distinct in tf. radians. 



Orbit, live times in head, nearly twice in muzzle ; depth, 3 2 times in total length ; head, four times. Free teeth, 

 three on each side, the anterior directed to the opposite, tin; posterior out w.ards to the same side ; the latter quite 

 long and sharp. Marginal teeth, very minute, those; of flu; mandible larger, three rows with crowns nearly distinct. 

 Length, live inches. 



8t, Martins, Dr. R. E. van Rijgersma. 



This species differs from the 8. lachrymoms of Poey in having six instead of four Tree maxillary teeth, and nine 

 soft anal radii. The color must bo quite different, as Poey mentions none of the peculiarities of this Ash, and says 

 there is a blue band from the orbit to the lip, which I have not seen in it. In S, atomarius the orbit enters a little 

 over four times the length of the head, and the caudal is vertical, not rounded. The coloration, from Prof. Poey's 

 description is quite different ; he connects also one more anal ray, but In; may incl ude the posterior half of the last.

OUYPTOTOMUS B08EUS, Cope, gen. Ot. Sp. HOT. 



Char. gen. Interior series of .teeth in both jaws consolidated into a, single cutting body on eaeh side, the exterior 

 scries entirely free in front, wanting on the shies. Spinous Kays, I). XI. A. III.; the dorsal flexible, terminating in 

 lilamcnts, and united by membrane at the base only. Oik; row of scales on each cheek, laps, double at the sides only. 



This genus has tin; dentition of Oallyodon with the numerous dorsal and anal spines of the group of Sarpe. The 

 pharyngeal teeth arc; identical with those of Oallyodon.
