M. carnosa Bowerbank. 

 Ban try Bay. Rev. A. Merle Norman. Of this species Prof. Oscar Schmidt 

 writes (Zweites Supplement der Spongien des Adriatischen Meeres, 

 p. 15): — " On the contrary, M. carnosa Bk. is something quite dif- 

 ferent. In its habit it approaches Myxilla rosacea Sdt. ; but the 

 very irregular spicules (Nadelziige) are enveloped in a horny cement 

 The morsel given to me by Dr. Bowerbank as M. carnosa, proves to 

 be identical with that likewise received from his hand as Halichondria 

 incrustans, of the spicula of which I give outlines (Pig. 17) ;" whence 

 it is probable that Microciona Bk. will equal Scopalina Sdt.
