 ri^HE Council of the Palseontographical Society, its officers and 

 1 subscribers, have reason for congratulation on the issue of their 

 sixty-seventh annual volume (for 1913), under date of February, 1914. 

 Age has not in any way diminished the lustre or lessened the artistic 

 beauty or scientific value of the work published from year to year by 

 this most important Society, and, despite the losses sustained both 

 amongst its distinguished authors and its valued subscribers, new 

 authors arise to add fresh, contributions to its pages and new subscribers 

 to replenish its funds, although the latter need to be greatly increased 

 if similar splendid volumes, such as that now lying before us, are to 

 be produced in this and future years. 



1. The sixty-seventh volume opens with the tenth, part of the 

 monograph on British Graptolites, by Miss Elles & Miss Wood 

 (Mrs. Shakespear), edited by Professor Lapworth. This valuable 

 work was commenced in the fifty-fifth volume, for 1901, and has 

 been continued (with only three intervals of a year each) up to 

 the present time. It will probably be completed in another part. 

 The Graptolites form a remarkable group which students of the 

 existing Hydromedusge generally dismiss in a very summary fashion as 

 "a class known only in a fossil state, divided into three orders, 

 which possibly bear but little genetic affinity to one another " : 1, the 

 Dendroidea; 2, the Graptoloidea — («) Monoprionidse, {b) Diprionidse ; 

 3, Retioloidea. But as among existing forms referred to this class 

 their life-history has yet largely to be worked out, we may rejoice 

 to find that by the combined labours of a large number of able 

 investigators the Graptoloidea have now been well and carefully 

 defined and have become, as zo7ial indices, of the highest importance 

 in the Lower Palaeozoic rocks. 



The first detailed arrangement in successive chronological zones 

 was made by Lapworth in his memoir " On the Geological Distribution 

 of the Rhabdophora " (Ann. Mag. Nat. Hist. (5), vols, iii-vi, 1879-80).
