Figure 11. — Austrofundulus stagnalis, new species: Holotype (U.M.M.Z. No. 141918), 

 31.5 mm. in standard length. Drawn by Mrs. Aime M. Awl. 



Remarks. — This new species may be distinguished from the other 

 two forms in the genus Austrofundulus by its wider upper lip, longer 

 pectoral fins, and crowded small scales on the breast. The key on 

 page 82 should enable the reader to identify this species from the 

 other two. 



Named stagnalis in reference to its habit of living in stagnant ponds 

 or pools.

 (R£o Apure, Venezuela). 



It is probable that Pellegrin's record for the Apure River actually 

 is for another species and his material should be restudied.

Dr. William Beebe kindly turned over to me a specimen 31.5 mm. 

 in standard length collected by him May 23, 1942, at Caripito, that 

 I tentatively identify with this species. Its caudal fin is more pointed 

 than usual in Rivulus. 



The two specunens before me (U.S.N.M. No. 94308) from Pitch 

 Lake, Trinidad, have 6 branched dorsal rays, 11 branched anal rays,
