THE NAUTILUS. 



NOTES. 



Note on a Preoccupied Name in Polyplacophora. — Mr. 

 Tom Iredale has recently been good enough to call my atten- 

 tion to the fact that the specific name pilsbryanus, recently 

 proposed by me 1 for a chiton dredged by the United States 

 Fisheries steamer Albatross off the coast of Japan, is preoccu- 

 pied in the genus Ischnochiton, where I had placed it, by J. 

 pilsbryanus Bednall, 1896, 2 a South Australian species. Al- 

 though it is by no means certain that the Lepidozona group 

 to which this species belongs is correctly referred to Ischno- 

 chiton even as a subgenus, the fact that it was so referred in 

 my paper as printed necessitates the adoption of a new name 

 for the later species. The Japanese form I therefore propose 

 to denominate I. (L.) nipponica. 



It was my intention originally to describe the species as an 

 outright Lepidozona, but, not being ready to give my opinion 

 as to the proper position for the group, I thought it wisest in 

 the final draft of the paper conservatively to refer it back to 

 Ischnochiton. It happened at that time that Bednall's paper 

 was inaccessible to me, and this fact, together with my un- 

 familiarity with its contents, prevented my discovery of the 

 existence of his prior name until too late for the proper cor- 

 rection to be made in my paper. — S. S. Berry. 



I ran into a curious bit of coincidence on Cerros Island. I 

 took Epiphragmophora veatchii only on one very peculiar 

 tree and never more than two to a tree. I brought home the 

 flowers and leaves, which I sent to the California Academy 

 for diagnosis. The tree turns out to have been taken orig- 

 inally on Cerros Island. It was described originally as Rhus 

 veatchiana, and Dr. Gray afterwards made a genus Yeatchia- 

 for it. — Fred Baker.
