Collyrites ringens. —‘* Conglomerate-Bed,” Maes Knoll, Dundry 
Hill, near Bristol (L.R.); West-End Quarry, Dundry Hill 
(J.W.D.M.) ‘*Top-Beds,” Dorset. Fullers’ Earth (basal 
portion—hemera zigzag), Midford (J.W.T.) 
COLLYRITES OVALIS (Leske), var. DEPRESSUS, Paris. 
Collyrites ovalts.—Doulting Beds (Zrwuelled and inter-Zrueller- 
sigsag). See page 18. 
DIPLOCIDARIS WRIGHTI, Desor. 
Radioles of considerable size, and agreeing precisely 
with that given by Wright in his “ Monograph” (PI. XLL, 
fig. 6), are not uncommon in the base of the Pea-Grit or 
top of the Lower Limestone at Well House, near Hares- 
‘field, Gloucestershire. Those obtained by Wright were 
all from the Pea-Grit of Crickley Hill. 
Diplocidaris Wrightt.—Murchisone, Well House, near Hares- 
field (H.M.H.); Crickley Hill (Wr.) 
DIPLOPODIA PENTAGONA, M’Coy. 
In some specimens of this species the diplopodous 
character of the pores is somewhat feebly marked, and 
shows them to be intermediate between this species and 
Pseudodiadema depressum. 
Diplopodia pentagona.—Upper Trigonia-Grit, Cowley, near 
Cheltenham. Clyfeus-Grit, Hawkesbury Upton, South Cot- 
teswolds. Upper Coral-Bed, Dundry Hill, where it appears 
to be fairly common. 
ECHINOBRISSUS CLUNICULARIS, auctt. 
This very persistent species ranges from the Inferior 
Oolite into the Cornbrash. Wright records it from many 
localities along the Cotteswold Hills, and notes that the 
larger specimens are inclined to be flattened, and the 
smaller ones pyramidal. Our experience, however, is just 
the opposite. 
Echinobrissus clunicularis.— Upper Coral-Bed, Stinchcombe 
Hill, near Dursley. C7Zyfews-Grit, Stoney-Hill Farm, Brimps- 
field, near Birdlip; Rolling-Bank Quarry, Cleeve Hill, near 
Cheltenham ; Midford, Somerset ; and the Doulting Stone 
and Rubbly Beds of Doulting, Somerset.
