 and on " a rough hilly bank near Ringing Low, five miles from 

 Sheffield, July 1844; the plant accompanied by Vaccinium Vitis-Idaa, 

 &c,, and growing among a profusion of LastrcBa oreopteris." It is 

 the A. dentifera (DeCand. Prod. vi. 25), but that is not separated from 

 A. tanacetifolia by many, of which it seems to be only a variety. —

On the Characters separating the four great Divisions of the Animal 

 Kingdom. By J. E. Gray, F.R.S. 



Great attention has been paid to the anatomical character which 

 separates the four great divisions of the animal kingdom, but com- 

 paratively little attention has been paid to the external form of the 

 groups and the characters furnished by their supports.

ON THE GENUS CALOPTYLUM. 



To Richard Taylor, Esq. 



Haslar Hospital, Gosport, January 12, 1847. 

 Dear Sir, — In the Ichthyology of the voyage of the * Sulphur' I 

 described a fish from the collection of Sir Edward Belcher which 

 I then considered to be the type of a new genus under the name of 

 Caloptylum. Mr. Thompson lately called my attention to the Breg- 

 maceros MacClellandi published by him in the fourth volume of your 

 * Annals,' p. 184 (April 1840), which is evidently of the same genus, 

 but most probably another species. Bregmaceros is therefore the 

 prior generic appellation. I remain, faithfully yours, 



John Richardson. 



* The second valve is sometimes reduced to the form of a lid or opercu- 

 lum, and sometimes entirely wanting, but is often found in the foetal state 

 when wanting in the adult animal.
