supercilium (commencing at the base of the maxilla and 

 reaching to the sides of the neck), chin, cheeks, throat, breast, 

 and shoulder-edge pure unsullied white ; crown and nape 

 bright ochreous ferruginous ; back and upper tail-coverts 

 ochreous olive; wings when closed ochreous brown; middle 

 rectrices brown, washed with ochreous, remainder with outer 

 webs coloured like the middle pair ; inner webs pure brown ; 

 the terminal portion of all the rectrices hardly tinged with 

 ochreous ; abdomen, flanks, thigh, and under tail-coverts 

 ochreous brown, the ventral region exhibiting a brighter fer- 

 ruginous tint ; bill yellow, probably red in the fresh skin. 



Wing 3*62 inches, tail 4'87, tarsus 1*25, bill, from nostril 

 (in a straight line) l'OO. 



Hab. Kareen Hills, Burma. 



Munia fumigata, n. sp. 



Above dark brown, deeper on the head ; rump white ; quills 

 above and externally deep brown, on the borders of the inner 

 webs pale tawny rufous, most developed on the secondaries 

 and tertiaries ; tail jet-black, the middle pair of rectrices being 

 slightly elongated ; chin, throat, and cheeks concolorous with 

 the head ; ear-coverts brown, with pale edgings ; breast, 

 abdomen, and flanks dingy white, the breast-feathers with

 M. acuticauda, Hodgs., but to be readily distinguished by the 

 absence of pale shafts to the dorsal plumage. 



LVIII. — Reply to Dr. J. E. Gray's Observations on certain 

 Species of Sponges described in the ''Proceedings of the Zoolo- 

 gical Society 1 for 1873. By Dr. J. S. Bowerbank, F.R.S. 

 &c. 



Dr. Gray has made so many inaccurate assertions in his obser- 

 vations on my descriptions of some sponges in the ' Proc. Zool. 

 Soc' for 1873, that I must request space to correct his mis- 

 apprehensions on these subjects. Had he confined himself 

 to legitimate criticisms on the subject, I should not have 

 thought it necessary to controvert his hastily formed opinions. 

 In these explanations I shall follow the order in which 

 Dr. Gray has treated these matters in the ' Annals and Maga- 

 zine of Natural History ' for September 1873.
