 1902. Pseudogrammoceras thrasu, Emend. Amm. Nom., p 5. 



Description. — Subplaty-subleptogyral, subcrassicostate to costate, periphery 

 convexitabulate. 



Distinction. — From P. subquadratum, the less coarse ornamentation, and the 

 more oligogyral character; from P. Saemanni, see p. cxlix, below. 



Locality and Stratum. — Gloucestershire : Coaley Wood, Bed 8, p. 45 (by

figs. 3—5. 

 1902. Pseudogrammoceras Bingmanni, Emend. Amm. Norn., p. 4. 



Remarks. — Denckmann's two examples differ — one (PL v, fig. 4) is more 

 umbilicate and less coarsely costate than the other (PL vi, fig. 5). My examples 

 agree in proportions with the first, in costation more with the second. 



Distinction. — From P. thrasu, thinner, and. with a more fastigate periphery. 



Locality and Stratum. — Gloucestershire : Coaley "Wood, Bed 7, p. 45. 



6. Pseudogrammoceras regale, S. Bud-man. Suppl., Figs. 134 (p. clxvii), 138 



(p. cxlvi). 



Hon. — Subplaty-subleptogyral, latumbilicate, subspissicostate, periphery 

 convexifastigate. 



Distinction. — From P. Bingmanni, thinner, more finely ribbed, and with a 

 slightly larger umbilicus. 



Remarks. — Is too thin for Denckmann's Ammonites Bingmanni in his Plate v,fig. 4. 



Mr. G. C. Crick, F.G.S., kindly compared my figured example with Wright's 

 Harpoceras radians in his Plate lxxiv, figs. 1, 2, and writes: " I believe it to be 

 specifically distinct." See P. Struchmanni, p. cxlviii, below.
