1944, and "Pygidium monodolfi, A New Catfish from Venezuela," 

 Journ. Washington Acad. Sci., vol. 35, No. 1, pp. 29-31, fig. 1, 

 January 15, 1945 (near Caracas). In addition I have published two 

 other recent papers on catfishes from Colombia: "A New Loricariid 

 Catfish from the Kio Truando, Colombia," Copeia, 1944 No. 3, pp. 

 155-156, September 30, and "A New Genus and Species of Pimelodid 

 Catfish from Colombia," Joum. Washington Acad. Sci., vol. 34, 

 No. 3, pp. 93-95, fig. 1, March 15, 1944. 



A few errors in my report on the catfishes of Venezuela have been 

 observed, and I take this opportunity to correct some of the more im- 

 portant ones. On page 182, 11a should read without, and on the next 

 page 36, next to last line should read 6 + H or 12 instead of 6 + 17. 

 The tenth line, third paragraph p. 335, should read 47.6, not 4.76. 



Addenda to my report on the catfishes of Venezuela, 1944: 



1. Hexanemathichthys rugispinis (Cuvier and Valenciennes). 1 specimen 275 

 mm., from mouth of Rfo San Juan, near Caripito, April 11, 1942, William Beebe. 



2. Selenaspis herzhergii (Bloch). 1 specimen for each — C.N.H.M. Nos. 41990 

 and 41989, from Lago de Maracaibo, W. H. Osgood, 1911. 



3. Pimelodus darias coprophagus Schultz. 1 specimen each, C.N.H.M. Nos. 

 41988, 42011, 42013, 42014, 42015, from Encontrados, W. H. Osgood, 1911. 



4. Pseudopimelodus villosus butcheri Schultz. Gomes, Occ. Pap. Mus. Zool. 

 Univ. Michigan, No. 494, p. 4, 1946 (Rfo San Juan, near Mene Grande, Venezuela). 



5. Microglanis poecilus Eigenmann. Gomes, Occ. Pap. Mus. Zool. Univ. 

 Michigan, No. 494, p. 15, 1946 (Cano de Quiribana, Rfo Apure into Rfo Orinoco, 

 Venezuela) . 



6. Microglanis iheringi Gomes, Occ. Pap. Mus. Zool. Univ. Michigan, No. 494, 

 p. 9, pi. 1, 1946 (Rfo Turmero near Turmero, Aragua; Carabobo, Venezuela). 



7. Perrunichthys. Recently a skin and head of a species in this genus was 

 found in the National collections collected by Prof. Orton probably at the junction 

 of the Napo and Maran6n Rivers of the upper Amazon. This head with skin 

 definitely represents a species distinct from P. perruno Schultz of the Maracaibo 

 Basin, but a better specimen should be obtained before describing and naming it. 



8. Dupouyichthys sapito Schultz. Cecil Miles, of Colombia, wrote to me on 

 July 2, 1945, that a man collecting for him in the Magdalena system just brought 

 a specimen of this species %\ith 6 or 7 almost fully developed eggs adhering to the 

 pelvic fins and the preanal region. Mr. Miles is to be highly complimented on 

 the discovery of this remarkable habit of incubation of eggs for the genus, although 

 such a type of egg incubation is known for certain Asiatic catfishes. He published 

 on this in Caldasia, vol. 3, No. 15, p. 454, 1945. 



9. Pygidium conradi Eigenmann. 9 specimens, 20 to 33 mm., from Guachaco 

 Cave, Rfo Caripe near Caripito, William Beebe, 1942. 



10. Ochmacanthvs flahelhferus Eigenmann. 1 specimen, 37 mm., East Caripito 

 Creek, William Beebe, March 6, 1942. 



11. Callichthys callichthys (Linnaeus). 2 specimens, 100 and 125 mm., from 

 Caripito, William Beebe, May 7, 1942. 



12. Hoplosternum thoracatum thoracatum (Cuvier and Valenciennes). 2 speci- 

 mens, 67 and 77 mm., Rfo Pablo, Caripito, William Beebe, March 19, 1942. 



13. Hoplosternum littorale (Hancock). 1 specimen, 117 mm., Rfo San Pablo, 

 Caripito, William Beebe, March 19, 1942.

 35341, Rfo Turmero, Venezuela, Ventura Barnes, September 24, 1937.
