260 FISHES OF WESTERN SOUTH AMERICA 
Type: Hydrocyon brevidens Valenciennes (non Hydrocyon brevidens Cuvier) = 
Salminus maxillosus Cuvier and Valenciennes 
Cauea to Rio Grande do Sul and La Plata basins 
Palate edentulous; salmonoid, abdomen long, separating the pectorals more 
widely from the remote ventrals than in nearby characinine genera; teeth of outer 
series larger than the inner both above and below; scales conspicuously large. 
329. SALMINUS AFFINIS Steindachner 
Salminus affinis Steindachner, 1880, Denksch. KIx. Akad. Wiss. Wien, XLII, 80, pl. vil, figs. 2 and 
2a, Cauca; 
Boulenger, 1898, Boll. Mus. Zool. Torino, XIII, 4, R. Santiago; 
Eigenmann, 1910, Rept. Princeton Univ. Exped. Patagonia, III, 446; 
Eigenmann, 1916, Ann. Carnegie Mus., X, 92, Honda; 
Kigenmann, 1922, Mem. Carnegie Mus., LX, 158. 
Rios Cauca, Santiago, Ucayali and Chanchomayo 
16024, 2, 228 and 240 mm., Rio Ucayali, Orellana, Allen, August, 1920. 
The occurrence of the species in the Ucayali seems to add plausibility to the 
Rio Santiago record in southeastern Ecuador, considered a doubtful identification. 
The Salminus collected by Eigenmann and daughter in the Chanchomayo were lost 
in transit, and were doubtless S. affinis.* 
The name corvina is misapplied to this genus. 
Subfamily: CHALCININAE 
The well-known Chalcinus and Chalcininae are hopefully retained despite 
Myers’ (1940) replacement by Triportheus Cope in order to vacate the name for a 
possible occupancy in the Chalcididae, as of Rafinesque, 1815. 
Genus 126: CHALCINUS Cuvier and Valenciennes 
Chalceus Miiller and Troschel (non Cuvier and Valenciennes), 1845, Horae Ichth., I, 15, angulatus. 
Chalcinus Cuvier and Valenciennes, 1849, Hist. Nat. Poiss., XXII, 258; 
Kigenmann, 1910, Rept. Princeton Univ. Exped. Patagonia, III, 440; 
Eigenmann, 1912, Mem. Carnegie Mus., V, 376. 
Triportheus Cope, 1871 (1872), Proc. Acad. Nat. Sei. Phila., XXII, 263; 
Myers, 1940, Stanford Ichth. Bull., I, v, 170. 
Type: Chaleinus brachypomus Cuvier and Valenciennes = Chalceus angulatus 
Agassiz 
Rio Magdalena to Guianas, Peru, and La Plata 
Compressiform, herring-like; lateral line decurved; preventral line trenchantly 
compressed; pectoral large; mouth small; a pair of conical teeth in mandible behind 
a series of lobed teeth; upper jaw with two series of teeth; caudal fin emarginate, the 
middle rays prolonged. 
*Specimens of Salminus collected by Nakashima at Iquitos were published by him (1941) 
as a new species, Holobrycon iquitensis. Dr. G. 8. Myers has seen the paper, and unhesitatingly 
places the species in the synonymy of Salminus hilarii, already known from the Amazons further 
down.
