farther, and from the junction of these crura are continued in one or 

 two volutions. If such conditions occur in t he older forms of the 

 Zygospiridae, there is no apparent reason why they may not occur 

 elsewhere among the various spire-bearing genera which have a 

 Iihynchonelloid aspect, and it seems a much more natural inference 

 that the development should have been in the line of the Ketziidae 

 or Rbynehospiridae." 



These remarks coincide with the genuine philosophic spirit whioh 

 has throughout characterized a work which not only fitly illustrates 

 the Natural History of New York State in long past ages, but forms 

 a valuable addition to knowledge of the Brachiopoda in general, and 

 one which cannot fail to exert an important influence on future 

 researches throughout the world. It is given to few to witness the 

 satisfactory completion of a great work conceived over half a century 

 ago, and we offer the veteran State geologist and palaeontologist of 

 New York our heartiest congratulations on the successful termination 

 of his lifelong labours. 1 



The Brachiopoda of the early Cambrian faunas of the St. John 

 group, New Brunswick, have also been studied with care by Mr. 

 (x. F. Mathew, who has described and figured several species in 

 a valuable memoir entitled "The Protolenus Fauna," communicated 

 to the Transactions of the New York Academy of Sciences in March 

 of the past year. 2 



Mr. S. S. Buckman gave some instructive "Notes on certain 

 Brachiopoda" from the Secondary deposits of England in his paper 

 " On the Bajocian of the Mid-Cotteswolds," contributed to the Geo- 

 logical Society of London 3 — serial studies of considerable importance, 

 chiefly relating to Rhynchonelloids. 



Lastly, the number of genera and species of recent Brachiopoda 



has been augmented by Mr. W. H. Dall, who has described and 



figured several interesting forms dredged in deep water during the 



"Albatross" expedition, "chiefly near the Hawaiian Islands, with 



illustrations of hitherto unfigured species from North-west America," 



in the Proceedings of the United States National Museum. 4 This 



paper defines Frieleia — a new genus of the Bhynchonellida?, with 



a. spondylium and a smaller number of brachial coils than are present 



in Hemithyris, to which genus it bears most external resemblance. 



It also clears up misconceptions relating to previously described 



forms such as Freuula Jeffreysii, and gives valuable data on specific 



development. . ~

1 We learn from a cosmopolitan list compiled by Mr. J. M. Clarke that 4.60 

 publications, relating to the Geology and Palaeontology of the State of New York, 

 were issued by various authors during the years 1876 to 1893 inclusive.
