History at Padua, a piece of the same species, under the denomination 
of Cornu vaccinum. I am, however, of opinion, that the ceratomor- 
phous fossil of Rogosniza, as well as the other at Padua, are Orthocera- 
tites, of which the species are now lost, or are the produce of more dis- 
tant seas. You will probably say, that the name of Orthoceratites is 
but ill suited to a recurvous fossil, and I agree with you ; so you may 
call it, if you please, Campilocerates.” Travels into Dalmatia, p. 159. 
Fossils, which I conjecture are of this genus, but of a different spe- 
cies from those described by Picot, exist in the neighbourhood of Ve- 
rona. The figures of these fossils, given by Spada, in his Catalogi 
Lapidum Veronensium Mantissa, Tab. i. and n. agree very closely 
with some of those given by Picot. They are thus described by Spada : 
“ Lapides monstruosi — basi subrotunda, in medio concava ; margine 
piano, latitudine unc. v. longitudine unc. vn. eras. unc. n. jumenti 
ungulam reprsesentantes, in conum fastigiati, tribus pnesentim fasciis 
antiqua parte horizontaliter distincta, quarum unaquseque verticalibus 
lineis striata est, postica vero lineis pariter verticalibus donata.” 
“ Reperiuntur etiam alii lapides supradictis fere similes truncati, et 
ungula destituti, fasciis lineisque horizontalibus insigniti.” 
The former of these, in Spada’ s figures, bears a very close resem- 
blance to a horse’s hoof ; and the latter very nearly resembles the 
largest of the hippurites figured by Picot. 
The specimen, Plate VIII. Fig. 1, copied from Picot s work, Plate 
VII. Fig. 1, shows one of these fossils of a frequent form, but of a 
smaller size than common, some of these fossils being at least four 
times the size of this specimen. In this figure the operculum is also 
seen, with its two openings. Some of these fossils are more of a cy- 
lindrical form, as in Plate VIII. Fig. 5, from Plate II. Fig. 2, of Picot’ s 
work. In this figure are shown, not only that part which is consi- 
dered by Picot as the siphunculus, a, but the septa, in nearly their 
natural situation, and the ridges which project into the cavity. 
We shall now proceed to the examination of the belemnite — a fossil
