front of this irregular area. Temporal plate irregularly and imperfectly 

 perforate; no adipose fin; origin of dorsal above middle of ventrals; plates 

 without keels. Color of type: a dusky stripe forward from eye, joining a dusky 

 stripe extending from snout to the nares; nares bounded by a dusky crescent 

 behind; back faintly spotted, the spots forming obscure continuations of the 

 prenasal stripe; first rays of pectoral, dorsal and anal and entire caudal ob-

Corydoras metae Eigenmann, sp. nov. 



13451 I. U. M., Type 54 mm. Barrigona, Rio Meta, Colombia. Coll. 

 Manuel Gonzales, 1914. 

 Head 3.25; depth 2.33; D. I, 8; A. I, 6; plates ff ; interorbital 2+ in the 

 head; eye 4; snout nearly half length of head; suborbital about half length 

 of eye; lower maxillary barbel just reaching gill-opening; dorsal spine equals 

 length of head less opercle, base of dorsal a little greater than its distance 

 from the adipose; pectoral spine very little shorter than head, extending 

 beyond middle of ventrals; humeral shields widely separated below, not en- 

 croaching on the breast or belly; a dark band across nape, through e^^es to 

 lower edge of head; a black band across end of caudal peduncle continued 

 forward along the middle of back and expanded on the dorsal to cover the 

 entire fin except the distal .4 of the last seven rays. Otherwise without

Albino or blind "capitanes" (Eremophilus mutisii Humboldt). 



I have recently received three specimens of "capitanes" from the Rio 

 Funjuelo at Usme Sur near Bogota. 



The largest measures a few millimeters over 160. It is not possible to 

 give the exact number owing to the curves. This specimen is without pig- 

 ment. The eye is apparent only on account of the lens and its overlying hyaline 

 skin. The eye measures 2 mm. in diameter. This measurement is taken 

 with the skin removed. The eye is not pigmented. 



Another specimen measures 130 mm. It is also without pigment except 

 in the eye. The eye seems to be fully pigmented and measures about 2 mm. 



The third specimen measures 133 mm. The caudal and all but a small 

 patch on the dorsal surface of the caudal peduncle are without pigment. The 

 region from the caudal peduncle to the head is pigmented, but much more 

 faintlj" than in normal specimens and there are in-egular pigment-free spots. 

 The sides of the head behind the eyes are free from pigment, the dorsal surface 

 of the head and snout are again pigmented. The eye is normally pigmented 

 and measures a little less than 2 mm. 



These specimens seem to be in all respects except the color identical with 

 the normal Capitan.
