VOL. XVI.(2) | INFERIOR-OOLITE ECHINOIDS 177 
PYGASTER SEMISULCATUS (Phillips), var. CONOI- 
DEUS, Wright. 
Pygaster semisulcatus, var. conoideus—Pea-Grit, Crickley Hill 
(Wr.) ; Cooper’s Hill, near Gloucester (L.R.) See page 183. 
PYGURUS MICHELINI, Cotteau. 
This form is very rare in the Inferior Oolite, and as far 
as we know, the record given below (of a very well-pre- 
served specimen) is only the second. 
Pygurus Michelini.— Anabacia-Limestones, railway-cutting south 
of the viaduct, Midford (J.W.T.) 
STOMECHINUS BIGRANULARIS (Lamarck). 
There is a slight variation in the proportionate height 
of the individuals of this species. 
The horizon at which this species is so abundant 
in Dorset is post-Garanteane. Mr S. S. Buckman has 
queried some specimens that were submitted to him 
as coming from a “ pre-zigzag” deposit. They probably 
occur in late 7ywedled or inter-Truellet-zigzag-Beds. The 
species seems to be common in this country only in 
Dorset. A single immature example, probable referable 
to this species, has been obtained from the Rubbly Beds 
of Doulting. 
Stomechinus bigranularis.—‘* Top-Beds,” Dorset ; Rubbly Beds, 
Doulting. 
STOMECHINUS INTERMEDIUS (Agassiz). 
There are two horizons along which this echinoid 
occurs in the Cotteswold Hills—the Pea-Grit, and on or 
about that of the Upper Coral-Bed. 
Stomechinus intermedius.—Pea-Grit, Huddingknoll, near Pains- 
wick (H.M.H.); Pea-Grit Coral-Bed, The Frith, near 
Painswick (H.M.H.); Crickley Hill (L.R.) At or near the 
Upper Coral-Bed horizon : Worgan’s Quarry, near Stroud 
(C.U.) ; Hazlewood Quarry, near Nailsworth (E.T.P.) ; 
and ? Upper Zvigonia-Grit, West-End Quarry, Dundry Hill 
(J.W.D.M.)
