Dick, who kindly furnished me with the material drawn, writes, 

 under date 13th July, 1915, that, in an infested area in Port 

 Macquarie, the stones were then almost white with the ova of 

 this borer.

A preliminary paper by Hombron ii Jacquinot, describing the 

 new shells obtained by the Astrolabe and Zelee Expedition, was 

 lately discovered by that active bibliophile, Mr. Tom Iredale. 

 In the official account of that expedition by Rousseau, and in 

 unofficial work by Le Guillou, a member of it, this memoir is 

 ignored. It has also been overlooked by Pfeiffer, Reeve, Tryon, 

 von Martens, Smith, and every writer on the subject. 



Examining the nomenclature of this species, in 1912, I con- 

 cluded that the name to be adopted for this shell from Warrior 

 Tsland was Helix cyclostomata, published by Le Guillou in 1842. 

 It now appears that the name of stranynlata was published a 

 year earlier, instead of many years later, than cyclostomata. 



Another consequence of the establishment of U. stranynlata 

 as dating from 1841, is that H. stranynlata, proposed by C. B. 

 Adams in 1849, becomes invalid.

Here it again becomes necessary to restore the older but 

 forgotten name. In his independent publication of the new 

 species obtained by the expedition. Dr. Le Guillou seems to have 

 been either careless or disloyal.
