mentioned as resembling the common scallop (of which no specimen was sent home) is probably the 

 P. (Equivalvis, which is characteristic of the inferior oolite ; the Helix mentioned also may possibly 

 be Ampullaria nobilis which accompanies the Cirrus in the lower beds of the mountain limestone of 

 England and Ireland."

16 — Belemnites sulcatus, Sillot, Miller, (Trans. Geol. Soc, 2d series, vol. II, pt. I, 

 pi. 8, fig. 3, 4, and 5.) Bel. apiciconus, Blainville's Memoire, Lias, inferior 

 oolite. 



15 Alveolus of a Belemnite, perhaps of B. sulcatus — Orthocera conica of Min. 



Con. tab. ix, although called an orthocera, is only an alveolus similar to this. 

 PI. II, Fig. 19 — Avicula (rather than pecten), new species. 



22, 23— Spirifer striaius. (Min. Con. tab. cclxx.) Mountain limestone. 

 25 Cast of the interior of the same shell. 



2i—Producta scabricida. (Min. Con. t. Ixix. fi^. 1.) This and the Spirifer are in 

 a stone strongly resembling some of the Transition slate of England. 



26 — Astarle planata, var. (Min. Con. tab. cclvii.) Inferior oolite. A variety of 



this shell is found at Bayeux in Normandy, and is called Crassina modiolaris. 



28 — Nucula, an unnamed species ; simitar fossils occur in the mountain lime and lias. 



29 — strongly resembles a portion of some large Inoceramus, but is not perfect enough 



to determine." 



Of the other shells depicted in the plates, there were at that time no duplicates 

 for transmission to England. The shells in Plate III, are for the same reason 

 unnamed.
