350 Mr. H. J. Carter on some West-Indian 



With flesh-spicule. 



Spongia Dysoni, Bk. This is the name on the largest 

 specimen of this sponge in the British Museum, presented in 

 1862. = Hymeniacido7i pidvinatus, Bk., on a small specimen 

 of the same species presented in 1872. At Belize, the locality 

 of this sponge, an enormous specimen is said to have been 

 found growing on a rock which could not be touched with the 

 oar of the boat ; and hence its head alone was taken off for 

 preservation. It is still undescribed ; but there are many 

 specimens of it in the British Museum under my running 

 no. 457, the two largest of which are flat pieces, registered 

 nos. 66. 5. 24. 12 and -13, labelled " Spovgia Bysoni^'' the
