C. kryophilus. Grun., Denk. Wien. Ah., 1884, p. 81, pi. iii. (C), 
fig. 21. — Diam. *044 mm. Central space rounded, indistinct, about 
of diam. broad, bearing isolated rounded granules. Markings 
polygonal, minute ; rows fasciculate, those composing each fasciculus 
parallel to the radial row at its middle ; a single prominent spine 
inserted near the border, outside of this a circlet of numerous, 
closely placed minute apiculm — Janisch, Gazelle Exped., taf. iii. 
fig. 3. 
Distinguished from C. lentiginosus , Janisch, by the larger spine 
and by the apiculi, and from C. polyacanthus by the smaller hut 
more numerous apiculi. 
Habitat . — Cape Wankarema, N. Siberia (Grunow). 
C. symbolophorus. Grun., Denk. Wien. Ak ., 1884, p. 82, pi. iv. 
(D), figs. 3-6. — Diam. *085 to T75 mm. Surface convex. Colour 
at centre steel grey, an opaque ring towards the semiradius, whence 
dark radial hands proceed outwards. Central space small, and usually 
branching into a distinct star with 3 to 5 rays, sometimes absent, but 
around the central area a similar star with 3 to 5 lanceolate rays. 
Markings polygonal, decreasing regularly outwards ; towards the 
centre 6, towards the border 8 to 9 in *01 mm.; fasciculate, those 
composing each fasciculus parallel to the radial row at its middle ; 
secondary oblique decussating rows faint, often somewhat curved 
outwards. Border narrow, hyaline. — Symbolophora, sp. Ehrb., Grun.,

* In the collection of F. W. Griffin. Mr Grove remarks that he has never 
seen this species in the Oamaru deposit, and greatly doubts its presence there, 
it being a form which may easily adhere to tubes and beakers,
