1 1 examined the specimen, 8656, in the Jardin des Plantes. It is recorded as from Bresil Merid. 

 Aug. St. Hilaire, Aout, 1822. Lat. line about 35; A. about 25. The specimen is stuffed and varnished 

 and it is impossible to say what may have been its original proportions. Dorsal behind the ventrals. 

 A caudal band to end of middle rays. 



2 Gill assigns the following characters to his A. caroiinae: — Maxillary ceases in front of the vertical 

 from the pupil and end of first suborbital. Dorsal considerably behind origin of ventrals; pectorals 

 reaching beyond ventrals. Eye about equal to the slightly convex interorbital, 3 in the length of the 

 head. Depth 2f; head 3f ; A. 26; scales 6.5-37 or 38-5; a humeral spot.
