 H, leo, from the East 'Indies. Neither in the descriptions, nor in 

 the figures given of the latter, are the deep red colour of the spinous 

 dorsal, and the spots behind the eye mentioned. ^loroover, the 

 dorsal spines of the East Indian specimens are rather thicker, but 

 equally long. Dried specimens are entirely similar in other respects.
