plants as belonging chiefly to "the natural monocotyledonous 

 Orders, Filices, Lycopodiaceae, Equisetaceae, and Cycadaceae," with 

 associated fragments of dicotyledonous species. The plant-hearing 

 sediments he describes as principally such as might be deposited by 

 rivers varying in force, and subject to intervals of feebler action. 

 The drawings of the plants are in many cases far from accurate, 

 and it is not an easy matter to recognize the original specimens. 

 Some of Phillips' type-specimens appear to have been lost, but 

 others have been identified in the York Museum and elsewhere. 

 ]n 1875 a third and much enlarged edition of Phillips' memoir was 

 published under the editorship of Mr. Robert Etheridge. Professor 

 Phillips did not live to see the publication of the third edition of 

 his work; the concluding paragraph of the preface, written in 

 1874, the year of his death, is worthy of repetition. 1 



" The Yorkshire coast has ever been my delight : to sketch 

 its romantic promontories, to climb and measure its cliffs, to 

 investigate its numerous fossils and its rich variety of marine life, 

 may be recommended to every lover of natural beauty and to every 

 student of natural history. To them I bequeath what has been to 

 me a labour of love, a life-long enjoyment the study of the great 

 Mesozoic section here so plainly cut, not doubting that kindly 

 thoughts will accompany the corrections and additions which time 

 has brought, and still must bring, to the work which I now consign 

 to their use." 



The following list includes the species enumerated in the last 

 edition, together with the names used in the first edition and their 

 modern equivalents adopted in the present Catalogue. I have also 

 added the name of the museum where the figured specimens may 

 be seen, but there are still several species of which the originals 

 have not been discovered. 2

Some of Phillips' type-specimens are referred to by Platnauer (91) as being 

 in the York Museum.
