CATFISHES OF THE GENUS CORYDORAS — WEITZMAN 119 



Corydoras fotcleri Bohlke 



Figures 3 and 4 



Corydoras foiuleri Bohlke, 1950, p. 2G (original description; type locality: Cano 

 del Chancho, near Pevas, Peru). 



Holotype: SU 16115, a female 66.0 mm. in standard length, 

 collected December 13, 1941, by Mr. William G. Scherer at Cafio 

 del Chancho, near Pevas [Pebas], Peru. 



Diagnosis. — Corydoras fowleri may be distinguished from other 

 known species of Corydoras by the following combination of characters: 

 Snout relatively long, about 25% of body length without head. 

 Least caudal peduncle depth about 55% of snout length. Imbricated 

 thoracic and abdominal plates present. Dorsal fin spine weaker and 

 shorter than pectoral fin spine. Predorsal length about 67% of 

 postdorsal length.

Description. — (See table 1 for measurements.) For explanation 

 of descriptive pattern below, see p. 117. 



Body elongate, especially slender posterior to dorsal and pelvic fins; 

 greatest body depth 3.3 (30.8%). Least depth of caudal peduncle 10.0 

 (10.0%). Dorsal fin origin much nearer to snout tip than caudal 

 fin base. Distance between snout tip and dorsal fin origin 

 2.3 (43.4%). Distance between snout tip and anus 2.0 (49.5%). 

 Anal fin origin to snout tip 1.2 (80.0%). Lateral scutes 24/21. 

 Abdomen and thorax entirely covered with small- to moderate-sized 

 imbricated plates. Azygous middorsal scutes 5 anterior to adipose 

 fin, 1 anterior to dorsal fin. Pectoral fin base incompletely sur- 

 rounded by coracoid, interval or hiatus filled with moderate-sized 

 plates continuous with those of abdomen and thorax. Distance 

 between coracoids 7.8 (12.9%). Head length 3.8 (26.6%); gi-eatest
