Adult female. Similar to T. lineatum, but larger, with the venni- 

 culations on the upper surface much finer, and with the axillaries 

 and long flank-feathers dark slaty grey, narrowly baiTed with white : 

 " bill black, the under mandible below yellow ; feet dark ochraceous ; 

 iris and orbital skin primrose-yellow" (H. Durnford). Total length 

 28 inches, culmen 4, wing 13-4, taU 5-2, tarsus 4-4. 



Count von Berlepsch is quite right in his identification of the 

 Salta specimen, collected by Mr. Durnford, which is now in the 

 British Museum ; and, as he has got specimens of the same bird from 

 Paraguay, there can be little doubt that they belong to the species 

 described by Azara and called Ardea mannorata by Yieillot. The 

 Salta specimen has the feathers slightly advanced on the cheeks, but 

 not so much as in A. fasciatum, and I find that there is a consider- 

 able difference in specimens as regards this character.

3. Tigrisoma bahiaB. (Piatell. a.) 

 Tigrisoma tigrinum (nee Gm.), Bp. Consp. ii. p. 556 (1855). 



Adult. Similar to T. Uneatum, but distinguished by the breast 

 and abdomen being regularly barred with dusky brown or blackish, 

 the bands being very broad and equal in width to the rufous inter- 

 spaces. Total length 24 inches, culmen 4-2, wing 10-8, taU 4-2, 

 tarsus 4. 



It is somewhat surprising that I cannot find any name for this 

 apparently very distinct bird, nor does it appear to have been noticed 

 by any ornithologist, though Bonaparte has taken his description 

 of T. irasiliense from a specimen of T. haJivp. The references to 

 all the Tiger Bitterns of Brazil are more or less confused, and the 

 synonymy is very difficult to unravel.
