Having given a good deal of study to the group which clusters around the 

 above specific name, I have modified the views expressed in my preliminary 

 paper. I had not then had the opportunity of studying the large series of 

 specimens, recent and fossil, contained in the Jeffreys collection. 



Not only am I obliged to review my own opinion, but I find myself wholly 

 unable to accept the views of Dr. Jeffreys, expressed in his " Lightning and 

 Porcupine Mollusca," Part VI. pp. 97, 98 (P. Z. S. 1883). 



Primarily I find two fossil species, which appear to be the forerunners of 

 the group, and one of which appears to be found in a recent state. They are 

 Trochus cinctus Philippi, and Solariella maculata Searles Wood. The first 

 has somewhat the form of Solariella amabilis Jeffreys, but was a brightly col- 

 ored shell, and to my mind appears perfectly distinct from any of the recent 

 forms and from Wood's species. 



Wood's species is (according to specimens identified by Professors Dewalque 

 and Seguenza) identical with Turbo moniliferus Nyst, non Sowerby, which is 

 the Solarium turbinoides of Nyst subsequently. Wood's name has precedence.
