EIGENMANNIA GOAJIRA. new species 



Plate 1, B 



Holotype.— V.S.N. M. No. 121596, 500 mm. in total length and 385 

 mm. from snout tip to end of anal fin base, collected by Leonard P. 

 Schultz, February 24, 1942, in the Rio Socuy, 3 km. above its mouth. 



Paratype.—\J.S.1<^.M. No. 121597, 430 mm. total length (with 

 regenerated tail), and 347 mm. from snout tip to end of anal fin base, 

 taken along with the holotype and bearing same data. 



The types were collected over a sandy to muddy bottom. 



Description. — Measurements were made on the holotype and para- 

 type, and these data, expressed in hundredths of the distance from 

 tip of snout to rear end of anal-fin base, are recorded in table 8. 



The following counts were made, respectively, for holotype and 

 paratype: Anal rays 263 and 255; pectoral rays ii, 18-ii, 19 and ii, 

 16-ii, 17.

• This specimen, U.S.N.M. No. 62543, was reported upon by Eigenmann and Bean (Proc. U. S. Nat. 

 Mus., vol. 31, p. 666, 1907) as Eigenmannia troscheli, but I now identify it as E. conircatria Eigenmann and 

 Allen. 



> Regenerated tail. 



The body is elongate, compressed, but the tail is rounded, and the 

 length of the tail behind anal fin is contained 2.9 times in length of
