188 INFERIOR OOLITE AMMONITES. 



species than that it occurs in the Jurense-zone. It is true that the Yorkshire 

 specimen came from the Striatulmn-heds ; but it seems to me possible that the 

 Striatulnm-beds of that district may also contain what, in the more developed 

 Gloucestershire deposits, I should call Dispansum-heds. 



PI. XXVII, fig. 3, represents a side view of a specimen which Mr. Hudleston 

 obtained at Peak, Yorkshire, and has kindly lent to me for the purposes of this 

 work ; fig. 4 shows the back view. Fig. 5 illustrates the side view of a specimen 

 with fasciated ribs collected by the late Dr. Lycett at Frocester Hill and by him 

 sent to my father ; fig. 6 gives the front view.

figs. 39, 40. The type-figures. I have had a copy 

 of these figures reproduced in a woodcut (fig. 2) so 

 that full comparison may be made. 



1830. Ammonites badians, Zieten. Verstein. Wiirttemburg, pi. iv, fig. 3. This 



is Orammoceras toarcense (d'Orbigny). 



1837. — — Bronn. Lethsea geognostica, pi. xxii, fig. 5, is pro- 



bably a Qrammoceras. 



1844. — — d'Orhigny. Ceph. Jurass. ; Pal. Fran9., pi. lix. This 



is what I now call Gramm. Orhignyi (p. 184). 



1846. — — DEPBESsus, Quenstedt. Cephalopoden, pi. vii, fig. 4, 



is Oramm. toarcense (d'Orbigny). 



1846. — — DEPBESSUS, Qweras^ec?^. Ibid., pi. vii, figs. 5, 6. These 



agree very closely with Reinecke's figures, and show 

 the true slow coiling ; also they have the ribs 

 straight on the lateral area, and a suture-line 

 indicative of Dumortieria. They only difier from 

 Eeinecke's figure in having less carina, and in one 

 having a thicker, the other a thinner and longer 

 aperture. 



1846. — ■ — DEPBESSUS, Quenstedt. Ibid., pi. vii, fig. 8. I am 



uncertain about this fragment. Its ribbing re- 

 sembles that of Oramm. toarcense, but its suture- 

 line inclines more to that of Haugia. 



1846. — — C0MPHESSU8, Quenstedt. Ibid., pi. vii, fig. 9. This 



is Haugia Eseri (Oppel). 



1846. — — costula, Quenstedt. Ibid., pi. vii, fig. 11. This is 



Dumortieria Munieri, Haug.
