that the "unspotted eggs . . . confirm van Rossem's description." These 

 accounts need to be checked with further observations as eggs of this 

 species in the U.S. National Museum are Hghtly spotted. The mark- 

 ings are faint and are seen only on close scrutiny. 



The set of 2 eggs in question w^as collected April 20, 1903, near 

 Papayo, Guerrero, by E. W. Nelson and E. A. Goldman. Both are 

 very light pale glaucous-green, marked sparingly and indistinctly with 

 scattered, irregular dots of pinkish buff. They are subelliptical in 

 shape, and measure 56.6x43.5 and 58.1x45.3 mm. Nelson's field 

 notes state that the nest of sticks, slight in structure so that light 

 showed through it from below, was placed about 7 meters from the 

 ground on a fork of a nearly horizontal branch in a mangrove that 

 stood in the open at the shore of a lagoon. 



There is a skin in the British Museum from Laguna Castillo, south- 

 ern Veraguas, taken by Arce in 1869, and W. W. Brown, Jr. for- 

 warded one from the same province secured on the "Sona River" (the 

 Rio San Pablo, near Sona) July 21, 1901 (Bangs, Proc. New England 

 Zool. Club, vol. 3, 1902, p. 19). I have recorded them on the lower 

 Rio Santa Maria below Paris, Herrera, February 24, 1948, at Punta 

 Mala, March 27, 1948, along the Rio Caldera at the southern end of 

 the Azuero Peninsula, March 11 and 20, 1957, and have found them 

 regularly in the marshes adjacent to the La Jagua Hunting Club. I 

 took one on April 17, 1949, near the mouth of the Rio Bayano, below 

 Chepo, and Griscom reported one seen on March 7, 1927, at Chiman, 

 where I heard them calling at night on several occasions in February 

 1950. This is the most eastern locality at which they have been re- 

 corded on the Pacific side. The report by Chapman (Life in an Air 

 Castle, 1938, p. 226), for Barro Colorado Island, "observed rarely. 

 No specimens" must refer to Tigrisoma I. lineatum as Heterocnus 

 mexicanus has not been found that far inland. 



In connection with the single record for Perme, San Bias, it is of 

 interest to note another in the Chicago Natural History Museum, orig- 

 inally in the collection of C. B. Cory taken March 22, 1881, that is 

 labeled "Mouth of Rio Atrato, Antioquia, Colombia."

Known from the bare-throated tiger-bittern in any plumage by the

 space at either side.
