AMMONITES RADIANS. 189 



1852. Ammonites hadians, Ohapuis et Deivalque. Foss. Luxembourg ; Mem. cour. 



et Mem. des sav. etrang., pi. x, fig. 3; pi. xi, fig. 1. 

 This is probably a variety of Qramm. Orhignyi, but 

 the ribs do not appear to have been quite correctly 

 delineated. The side view shows them much less 

 projected ventrally than would be expected from 

 the front view. 



1853. — — Amalthei, Oppel. Mittlere Lias Schwabens, pi. iii, 



fig. 1. This is perhaps Qramm. normanianum, 

 d'Orbigny (see Oppel, ' Juraformation,' p. 168). 



1853. — — NUMI8MALI8, Oppel. Ibid., pi. iii, figs. 2 a, b, p. 51. 



This is Gycloceras Stahli (Oppel, ' Juraformation,' 

 p. 168). 



1858. — — Quenstedt. Jura., pi. xl, fig. 9. This is a Dumor- 



tieria, and agrees with Reinecke's original figure of 

 Am. radians. 



1858. — — coMPEESsus, Quenstedt. Ibid., pi. xl, fig. 13, is 



Haugia Eseri (Oppel), but fig. 14 is Qramm. 

 toar cense, d'Orbigny. 



1865. — — Lycett. Amm. of Sands. ; Proc. Cotteswold Field 



Club, vol. iii. Qramm. fallaciosum, Saemanni, &c., 

 are referred to. 



1867. — — Meneghini. Lias supcrieur ; Pal. Lombarde, 4e serie, 



pi. ix, figs. 2 — 6. These are evidently species of 

 the " JaZ/acioswOT-group " (p. 200). 



1867. — — Meneghini. Ibid., pi. xi, fig. 6. This is probably a 



hollow-carinate Qrammoceras with the carina 

 broken ofi". Fig. 7 is perhaps Qramm. striatulum. 



1874. — — Bumortier. Etudes pal. Bassiu du Ehone, iv, pp. 60, 



61, The author notices the fact that the ribs of 

 Reiuecke's figure " ne sont pas flexeuses des I'ombilic 

 commes les Ammonites connues de tons les geo- 

 logues sous le nom de radians . . . ." 



1879. Haepooeuas aff. eadians, Branco. Unt. Dogger; Abh. z. geol. Spez.- 



Karte v. Elsass-Lothringen. This is probably 

 Dumortieria radiosa (Seebach). 



1882. — BADIAN8, Wright. Lias Ammonites ; Pal. Soc, pi. Ixiv. These 



are probably forms of Qramm. fallaciosum. The 

 real carina is absent. I have examined the original 

 of figs. 4 — 6 in the British Museum. 



1883. — — Wright. Ibid., pi. Ixxiv, figs. 1, 2. This is a fine 



specimen of my Qramm. fallaciosum var. Struck- 

 manni (p. 206). 



1884. — — Wright. Ibid., pi. Ixxxi, figs. 4—6. This is a 



variety of Qramm. fallaciosum.
