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

 and shonlder-edge piu*e unsullied white ; crown and nape 

 bright ochreous ferruginous ; back and upper tail-coverts 

 ochreous olive ; wings when closed ochreous brown ; middle

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

 Ramsay in the island of South Andaman. Nearly allied to 

 M. acuticaucla^ Hodgs., but to be readily distinguished by the

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

 Species of Sponges deso'ihed in the ^Proceedings of the Zoolo- 

 gical Society ' 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.
