464 MELVILL! THE PRINCIPLFS OF NOMENCLATURE, 
If they be disallowed the following names will have to be 
changed :— 
Castalia Lamarck 1819 antedated by Castalia Salisbury 1805 
[—Nymphea Z. in parte] (Vvmpheacee). 
Dacrydium Zorrell. 1859 __,, Dacrydium Solander 
1786 (Conifer). 
Modiola Zam. 1801 - Modiola Moench 1794 
(Malvaceae). 
Trigonia Bre. 1781 “f Trigonia Awblet 1775 
( Vochysiaceae). 
Verticordia S. Wood 1844 ,, Verticordia D. C. 1826 
(ALyrtaceae). 
(6) ‘The alteration of date from 1767 to 1758 likewise has 
no palpable effect upon Conchological specific nomenclature. 
But 814 species are propounded (including Serpulze, Lepades, 
and Sabelle), in the twelfth, as against 703 in the tenth 
edition. At the same time, it seems to me to cast a slur 
upon Linnzus’ memory. He laboured to attain a standard 
of perfection, and we who honour his memory must remember 
that he brought his work to a high pitch of excellence, and 
bequeathed it to posterity in as complete a form as possible, 
To take the tenth edition as a starting point is to deprive 
ourselves of many of the great benefits of his vast experience, 
extended and enhanced in every edition. 
(f) This rule is calculated to call forth much divergence 
of opinion. If it be true that by its becoming law many old- 
established genera (not many however in Mollusca) will fall, I 
shall advocate it being left alone. Personally, I think the 
Scomber scomber tautology not the reverse of pleasing. I certainly 
prefer Gemma gemma to Gemma Tottent. 
The Molluscan Branch of Zoological Nomenclature, as 
regards the genera, seems to be in better case than many of the 
other sciences, more especially Botany, now so assailed by the 
questionable lucubrations of Dr. Otto Kuntze.
