Professor Hall's volume of plates of the Palaeontology of New 

 York, illustrating the Lamellibranchiata of the Upper Helder- 

 berg, Hamilton and Chemung groups, containing, with a few 

 omissions, 80 plates, was issued in 1883, and is noticed in this 

 Journal for that year (vol. xxv). Since then, Plates 81 to 92 

 inclusive have appeared, and now we have Plates 35 and 42, and 

 93 to 96 inclusive. The text of the second part of Vol. V, Part 

 I, has also been issued, making the whole complete. Professor 

 Hall states that the number of species of American Paleozoic 

 lamellibranchs now known is over 1250 ; and that nearly half of 

 this number have been collected in New York from the Trenton 

 and later Paleozoic strata, and 500 from those above the Oriskany. 

 The study of the species was a work of great labor and difficulty, 

 and Mr. Hall is to be congratulated that the printing is finished. 

 All paleontologists will rejoice with him, and give due honor to 

 him and to the State of New York for this very valuable con- 

 tribution to American science. 



The Annual Report for 1882, of "the State Geologist," Mr. 

 Hall, (in 4to, instead of the usual 8vo form), is made up chiefly, 

 after a paper on the mode of growth of Fenestellae, of plates 

 of Fossil Corals and Bryozoans of the Lower Helderberg and 

 Bryozoans of Upper Helderberg, 33 in number, and 28 plates 

 illustrating the genera of some families of Bi'achiopods, being 

 part of a revision of the Paleozoic genera of this group — portions 

 of volumes of great paleontological interest yet to be published.

1. Botanical Necrology for 1885. — Supplemental to the bib- 

 liographical notices given in the January number of this Journal, 

 pp. 13-22, we should record the following obituaries : 



Jean-Etienne Duby, long one of the Genevese clergy and 

 not undistinguished as a botanist, died at Geneva, Switzerland, 

 November 24, 1885, at the age of 88. In the year 1828 he edited 

 the second edition of DeCandolle's Botanicon Gallicum, which 

 served an important purpose as the manual of French and Swiss 

 botany tor many years. In 1844 he produced his memoir on the 

 Primidacece, and his elaboration of that family for the Prodromus. 

 His other publications relate to the lower Cryptogamia. They 

 began in 1829 with a paper on the application of the principles of 

 taxonomy to a tribe of Algae : the latest, that we know of, was 

 upon some new or little understood Musci, and was published in 

 1869. With this venerable man passed away the last of the 

 colleagues of Aug. Pyramus de Candolle. 



The Brothers Tulasne. The elder brother, a botanist of 

 remarkable acuteness and sagacity, Louis Rene Tulasne, was 

 born on the 12th of September, 1815, and died at Hyeres, on the 

 22d of December, 1885, twenty years after he had abandoned all 

 scientific pursuits. Charles, born a year later, who published 

 no independent work, but drew most of the excellent figures
