Mr. E. A. Smith on three new Species of Helix. 451 



Section D ; I brought the question before the Committee, and 

 it was thought desirable that the Rules should be reprinted, 

 and a committee for the purpose was appointed ; but I was 

 subsequently informed that copies still remained for sale. If 

 applicants should fail to obtain them, and in that case think 

 it well to put themselves into communication with me, I will 

 take care that the matter shall be again brought forward in 

 Section D. 



I have taken this opportunity as an addendum to my notes 

 on Mr. Newton's communication to carry out an intention of 

 some standing to direct the attention of zoologists to what 

 is undoubtedly a common misapplication of a rule of nomen- 

 clature. 



With respect to the word Botany in Rule 10 the attempt 

 has long been given up to exclude the use of a botanical 

 generic name from Zoology, or vice versa, and the introductory 

 notes of the revised edition of the Rules (1865) intimate this. 

 This may be illustrated by a genus referred to in my notes in 

 last month's (April) ' Annals.' The genus Linckia, Nardo, 

 was rejected by Forbes because of previous use in botany. 

 Under altered views in this matter it is now in use for another 

 section of the original genus of Nardo than that to which 

 Forbes applied the name CribreUa.

 obliquis sculpti, ultimus minus convexus, similiter striatus, sed

 subnasuta, intus colores externos aliquauto obscuros exhibens ; 

 peristoma album vel superne pallide lilaceum, margine superiore 

 leviter reflexo, in medio depresso, inferiore latius expanso, albo,
