XXXVII.—Notes on an Examination of Lamarck’s species of 
Fossil Terebratule *. By Tuomas Davipson, Esq., Member 
of the Geol. Soc. of France. Illustrated by figures of all the 
species drawn from the original specimens. 
Tue natural history of the invertebrated animals by the cele- 
brated Chevalier de Lamarck is a work so generally consulted by 
all naturalists that it is unnecessary here to allude to its scientific 
value. Some parts however are not so clear as might be desired, 
owing to the state of science at that period, and especially from 
the want of figures illustrative of the text, so necessary an ap- 
pendix to all specific descriptions. 
The fossil Terebratule especially required some investigation, 
and on the suggestion of Mr. Morris, who had previously ex- 
amined the Lamarckian species, and other paleontologists, I 
determined to visit Paris in February last, and endeavour to ob- 
tain the loan of all the typical specimens described in Lamarck’s 
volume and preserved in the collections of that metropolis. 
Lamarck having had the misfortune of losing his sight, with- 
out the remotest hope of regaining it, during the publication of 
the sixth volume of his ‘ Animaux sans Vertébres +,’ M. Valen- 
ciennes, at his suggestion, took upon himself the determination 
of the species of the genus Terebratula that he was able to see in 
the Paris collections: so that it is in reality to M. Valenciennes 
that science is indebted for the publication of that part of the 
work relating to the Brachiopoda. On expressing to Prof. Milne- 
Edwards and Valenciennes my wish to imvestigate those speci- 
mens of Lamarck’s in the museum of the Garden of Plants, they 
at once in the most liberal manner (after having obtained the 
consent of the Executive Council of that establishment) lent me 
the specimens to bring to England in order that I might more 
carefully examine and illustrate them, and I here publicly express
