Echixoidea (regular). 
Cidaris BeJgicci, Cotteau. Bryozoan Crag, Aldborough. Identi¬ 
fied by comparing some connected plates with 
Cotteau’s figure. 
Cidaris pisum (P N. Sp.) A young example of a Cidaris from 
Aldborough, hardly larger than a small pea, the 
height and breadth nearly equal, tubercles large, 
may represent another species should larger examples 
be obtained. The Bryozoan Crag at Aldborough, 
contains a variety of forms incidental to this habitat 
that are usually passed over, the small lumps of Crag 
each requiring individual examination for the smaller 
Echinoidea and Crustacea. 
Diadema sp. Diestien sands of Lenham, Kent, spines only. 
Diadem a megastoma , A. Bell. A few examples of an apparently 
undescribed Echinoderm , with the test much rolled 
and the interior filled with a hard and compact matrix. 
The conditions of the fossils do not allow an exact 
diagnosis “ Test discord, apex flattened in every 
instance (apical disc broken away), peristome large, 
angulated, divided by notches into lobes corresponding 
with the straight poriferous zones, deeply recessed at 
the angles, tubercles fairly large, corresponding to 
the spines above referred to. Height J in., diam. j in.” 
From the condition of the test, and its localisation in 
the disturbed portion of the Red Crag, it is probably 
a deviation from the older Diestien beds. Loc. Middle 
(Red) Crag, Waldringfield. Mr. S. P. Woodward 
found a broken spine of Diadema in the Cor. Cr. 
Temnechinus Woodi, Agaz, of the species decribed by Forbes. 
Dr. Gregory groups three under the above name 
considering the variations to be due to sex or age. 
In these notes they are treated as distinct to allow 
for localisation. 
T. excavatus , Wood (female of T. Woodi , Greg.,) Cor. Crag, 
Sudbourne Park, Ramsholt, and Sutton, Red Crag, 
Foxhall and Waldringfield. 
T. melocactus , E. F. (male of T. Woodi , Greg.) Cor. Crag, 
Ramsholt and Sutton.
