206 BUCKMAN : AMMONITES FROM THE SCARBOROUGH LIMESTONE. 
This species was called by Bean A. triptolemus, as Morris and 
Lycett inform us ; but they rejected Bean's name. However, 
the sj)ecies is entireh' distinct in ornament, pro]3ortions and mode 
of growth from Am. hraikenridgii , d'Orbigny (= Normannites 
orbignyi, S. Buckman), and still more so from Am. hraikenridgii, 
J. Sowerby. On these shells, see S. Buckman, Ann. Mag. Nat, 
Hist. (8), i, 1908, p. 146. 
I have not seen the original specimen, nor a Yorkshire 
example like it, so the genus is not too certain. 
2. Teloceras sp. nov. 
1850, Ammonites blagdeni, Morris and Lycett (non Sowerby), 
Great Ool. Moll. (Pal. Soc), PI. XIV, Fig. 3. 
This is not A. blagdeni, J. Sowerby, nor A. banksi, J. Sowerb}^ 
nor the next species : it is a form which requires a new name. 
3. Teloceras coronatum, Quenstedt sp. 
1886, Am. coronatus, Quenstedt, Amm. Schwab. Jura, PI. LXVII, 
Fig. 1 only. 
A large specimen about 185 mm. in diameter, wholly septate, 
A\as submitted by Mr. Richardson. It is a species allied to 
A. blagdeni and A. banksi, but the peripher}^ is more arched than 
in either ; the ornament is more of the A. blagdeni pattern, less 
coarse than in A. banksi. 
4. Stemmatoceras subcoronatum, Oppel sp. 
1849, Ammonites coronatus oolithicus, Quenstedt, Ceph., PI. XIV, 
Fig. 4. 
1856, Ammonites subcoronatum, Oppel, Juraf. p. 376. 
A somewhat stout whorled specimen, about 140 mm. in 
diameter, was submitted by Mi*. Richardson. As the inner 
whorls are much obscured by matrix the identification cannot 
claim to be exact ; but the specimen has the general proportions 
and ornaments of Quenstedt's figure.
