seen moving in tlie water. Any foreign object is rapidly seized 

 and conveyed to tlie mouth, thougli I could not ascertain what 

 was their favorite food. They are very easily captured. By 

 turning over any block of dead or living coral four or five of them 

 will be seen slowly moving away. The fishermen seem to have a 

 dread of them, so they are quite unmolested, except by the 

 natui'alist or whatever marine enemies they may have. 



In the preceding observations only a few of the objects of interest 

 on our coral reefs have been touched upon. To deal with all 

 would require many volumes instead of essays. When we 

 remember what the sea coast is to the naturalist, we may form 

 an opinion of what a coral reef must be. The wliole structure is 

 the result of animal activity, and every portion on which the eye 

 rests reveals some new phase of animal life. We may take it as 

 certain that only a very suiall portion of our reefs have been 

 explored by naturalists, and that therefore there is no more 

 promising field of zoological discovery in the whole world, none 

 where the interest is greater, or where distinction may be more 

 easily won. For my own part the few weeks I spent in the coral 

 region were the most intensely interesting of any I remember in 

 a life-time of observation as a naturalist, and I trust that one 

 result of my few scattered notes will be to attract others on to the 

 same enchanting field. 



Eectification of the Nomexclatuee of Furpura anomala, Axgas.

South Australian specimens of a species of marine gasteropocl, 

 forwarded to Mr. Gr. F. Angas, F.L.S., under the generic title of 

 Mangelia, have lately been returned to me with the name of Purimra 

 ( Cronia) anomala, Angas. The description and figures of that 

 species, Proc. Zool. Soc, 1877, pi. v., fig. 1., are truly applicable
