IS CEETACEOUS CORALS OR AXTIIOZOA 
1. Cyclolites conoidea, SloUczka. PL X, Pigs. 4 — 5. 
Cyc. corallum ovatnm, eonoideo elcvatmn, crassiim, apice ohtiisc arciiato ; fossvla 
latmscnla, modice 'profunda, dimidinm diametri maj or is paulo super ante ; laterihus 
convexiuscule decUcihus ; septis numerosissimis, suh-granulaiis, suh-eequalihus, septimo 
qiioque septo plerumque fortiore ; hast in juniore modice concava, in adidto fere 
plana, Iccvigata, concenlrice distanter plicosa, medio paido tiimidula, peripheriam 
versus declivi atque radiatim striata, peripheria ipsa acute angulata. 
Altliough merely known from the two specimens figured, these are sufii- 
ciently well preserved to characterize the species. It is somewhat allied to Cyclo- 
lites conica and C. tindulata, hut differs from both by the great length of the 
central groove or fossula, which is rather broad and comparatively shallow, des- 
cending on either side of the longitudinal axis. The sides are moderately convex. 
The septa close together, not very fine, and nearly equal ; in most places each seventh 
or occasionally eighth septum appears to he somewhat thicker than the intermediate 
ones. The original edge of the septa lias only partially been observed, but they all 
appear to be rather sharply, though not densely, granular. The base is concave in 
the smaller, nearly fiat in the larger specimen, with a central thickened boss ; the 
epitheca is thick, concentrically folded, and towards the periphery marked with 
radiating striae. The peripherical edge itself is sharp. 
Locality . — Xear Valudayur ; two specimens in a whitish sandstone. 
formation, — Arrialoor group. 
2. Cyclolites F/ECATA, Stoliczlca. PI. X, Pigs. 6 — 9. 
Cycl. corallum ovatuni vel rotundate ovatum, modice elevatum, laterihus con- 
vexiusculis ; fossula centrali, satis qyrofunda, in longitudine dimidmm diametri majo- 
ris cequante ; sepitis moderate crassis, numerosissimis, sat distanter granulat is, qaoque 
quarto septo aut quinto alteris interpositis tenuiorihus fortiori ; basi concaviuscula, 
suh-lcevigata, theca murali tenui, distanter concentrice sidcata, atque peripheriam 
versus radiatim striolata. 
Diain. maj. speciniinis inaxinii 24, diam. min. 21‘5, alt. 8 mm. 
The corallum is ovate or roundly ovate, with a nearly flat, hut more generally 
somewhat concave base. The upper part is moderately elevated, with convex 
sides, and a centrally situated fossula, equaling in length half the longer diameter 
of the corallum. The septa are very numerous, and each fourth or fifth is 
stronger than the intermediate ones, which again differ in strength ; they are all 
somewhat distantly and not strongly granular, 'f he base is radiately striated towards 
the periphery.
