ADDITIONS TO THE LIST OF TABLE CAPE 

 FOSSILS, TOOETHER WITH FURTHER REMARKS 

 UPON CERTAIN FOSSIL SHELLS SUPPOSED TO 

 BE IDENTICAL WITH LIVING SPECIES. 

 By Robt. M. Johnston, F.L.S., Etc. 

 [;Read June 9, 1884.] 



On the last occasion on which we met I intimated to this 

 Society that Professor Tate was energetically engaged upon 

 the important work of thoroughly determining and settling 

 some of the more difficult points of classification with regard 

 to the fossil species of the Australian Marine Tertiaries 

 which were supposed to be identical with living forms. 



On that occasion, also, I pointed out that the fossil shell, 

 formerly referred to the living Fectunculus laticostatus, was a 

 very distinct species not identical with any known living 

 form, and accordingly I proposed for it the name of P. 

 McCoyi. Since that time I have received three important 

 communications from Prof. Tate prepared for this Society. 

 In one of them I am gratified to find that this distinguished 

 naturalist concurs with my determination in respect of P. 

 McCoyi. He also, among other suggestions, desired me to 

 re-examine and compare carefully the fossil forms hereafter 

 referred to with the living types supposed to be identical 

 with them, as he had doubts regarding the correctness of 

 their determination. Through the kindness of Captain 

 Beddome, who placed his valuable collection of the living 

 types at my disposal, I was enabled to carry out his wishes, 

 and as there was not sufficient time since then to allow of 

 the results of my examination to be communicated to Prof. 

 Tate, and afterwards included in his communication to this 

 Society, I have thought it best to prepare a separate note 

 upon the matters referred to me. 



The fossil forms more particularly referred to me for 

 re-examination and comparison with living types are the 

 following : — 



1. Crossed lahiata — Ten. -Woods. Fossil form, originally 



determined by the writer. 



2. Natica j^olita — Ten. -Woods. Fossil form, originally deter- 



mined by Rev. J. E. Tenison- Woods. 



3. Trivia Eiiropea. — Fossil form, originally determined by 



Rev. J. E. Tenison-Woods. 



4. Trigonia aaiticostata— McCoy. Fossil form, originally 



determined by Prof. McCoy. 



5. Syrnola bijasciata. Fossil form, originally determined by 



Rev. J. E. Tenison-Woods.
