’ Fossil Terebratule. 435 
this report as short as possible, I have simply added a few obser- 
vations after each Latin description of Lamarck or Valenciennes. 
In 1836 M. Deshayes published the 7th volume of his new 
edition of Lamarck’s work, to which he annexed numerous spe- 
cies and notes, but did not materially increase our knowledge of 
the fossil species described in the edition of 1819, from not 
having had the advantage of examining and comparing the spe- 
cimens in the original collection ; there are however some useful 
notes and references which may be consulted with advantage. 
The following is the order in which Lamarck’s species are 
described in the 6th volume of the ‘Animaux sans Vertébres.’? As 
the recent species have been often figured, it will simply be ne- 
cessary to give the list :— 
1. Terebratula vitrea, Lamarck (Linn. sp.). 
2. ———— dilatata, Lamk. 
3 pisum, Lamk. 
4., — globosa, Lamk. 
5. ———— rotundata, Lamk.

. ——— flavescens, Lamk.

. ———— sanguinea, Lamk. 
10. ———— Caput serpentis, Lamk. (Linn. sp.). 
11. ———— truncata, Lamk. (Linn. sp.). 
12. ——-—— pesittacea, Lamk. (Linn. sp.). 
Fossit SPECIES. 
13. Terebratula subundata (Sow. M. C. tab. 15. fig. 7). 
14, Terebratula carnea (Sow. M. C. tab. 15. fig. 5, 6). 
Obs. These two species are not to be seen in Lamarck’s col- 
lection. 
15. Terebratula depressa, Val. in Lamarck. PI. XIII. fig. 15. 
T. testa oblonga, transversim dilatata, supra coarctata et obtusa, striis 
concentricis leevibus : nate producta non incurva: foramine magno. 
Var. 6. testa minore : nate breviori. 
Obs. This species is perfectly characterized and found in the 
Tourtia beds of Tournay and Montignies-sur-Roc in Belgium, 
whence Lamarck’s specimens came ; it is strange however how 
little it was known, since M. le Vicomte D’Archiac, in his “ Rap- 
port sur les Fossiles du Tourtia,” Mémoires de la Soc. Géol. de 
_ France, vol. 11. 2nd series, p. 313. pl. 17. fig. 2 a, b, c, d, 3-10, 
1847, believed it new, and gave to it the name of Yerebratula 
Nerviensis, which is a synonym: in the Quarterly Jownal of the
