Mr. Thompson of Belfast informs me that this, so named 

 by Mr. Smith, as indicated, is Trochus millegranus of Phi- 

 lippi. 



Several very beautiful live specimens, brought up by the 

 fishing-lines, from the Bay of Aberdeen, in February, 1843, 

 were found by Mr. Beaton, Mr. Fergusson, and others of my 

 pupils. They are pure white, slightly transparent^ but other- 

 wise as described ; the largest seven-twelfths of an inch in 

 diameter, and about the same height. It is remarkable that 

 they were accompanied by several specimens of the beautiful 

 white variety of Trochus zizi/phinus, which they closely re- 

 semble in form. Two specimens found by Mr. Alexander 

 Mitchell, about the same time, are more strongly granulated, 

 and prettily marked with red dots along the spiral striae. The 

 apex in all the specimens is somewhat tinged with blue.
