440 Mr. T. Davidson on Lamarck’s species of 
marck’s collection at B. Delessert’s, as well as in the museum of 
the Garden of Plants, none of which however belong to Sow- 
erby’s type, but are referable to several distinct forms from va- 
rious deposits of different ages. Thus for example, those m the 
Garden of Plants, as well as one in B. Delessert’s cabinet, are 
oolitic ; others belong to the Neocomian beds, such as those 
shells figured and described by M. D’Orbigny in vol. iv. p. 75. 
pl. 506. of the ‘ Pal. Franc.’ under the name of Terebratula pre- 
longa, Sowerby: but M. D’Orbigny is mistaken as to his iden- 
tification of this shell with the ones described under that name 
by Mr. Sowerby. Besides these, we find two specimens which are 
probably Terebratula Sella, and as M. Deshayes justly observes in 
his new edit. of Lamarck, a great number of smooth Terebratulas 
with two plaits have been called Ter. biplicata, but which are 
quite distmet from Sowerby’s type, which belongs to the gault 
of Folkestone and Cambridge. 
32. Terebratula bisinuata, Val. in Lamk. PI. XIII. fig. 32. 
7’. testa subrotunda, subdepr essa, antiquata, fragili, leevi, superne bipli- 
cata: nate producta non incurva. 
Obs. This species belongs to the tertiary beds of the Pane 
basin, well figured and described by M. Deshayes, Coq. Foss. 
des Env. de Paris, tom. i. pl. 65. 1, 2. It has also received 
several other names, such as Ter. gigantea, which, according to 
Baron Leopold von Buch, would be the same as Lamarck’s type: 
several specimens are to be seen in B. Delessert’s collection. 
33. Terebratula Kleinii, Val. m Lamk. PI. XIII. fig. 33. 
T. testa ovata, depressa, subantiquata, leevi, superne biplicata creber- 
rime et subtilissime punctata : nate incurva. 
Obs. Several persons, and among others M..Deshayes (new ed. 
of Lamarck), refer to this species the Ter. globata of Sowerby. 
M. Valenciennes, who was the original describer of the species, 
convinced me of the mistake, which can be at once seen from 
three type specimens in the collection of the Garden: of Plants ; 
one of which 1 have figured in my plate: it belongs to the oolitie 
beds, probably from Normandy. Lamarck’s eae to Ano- 
mya Terebratula of Linneus may have led to this mistake. M. 
Db Orbigny has also fallen into the common error in his ‘ Pro- 
drome’ by attributing Ter. globata to Lamarck’s species. 
34. Terebratula Pedemontana, Val. in Lamk. Pl. XIV. fig. 34. 
7’. testa subrotunda, subdepressa, transversim striata, superne bian- 
gulata: umbone elevato, nate recurva. Coll. Museum. 
Obs. M. Valenciennes in his description of this species states 
that it approaches the preceding one above all by the rounded.
