clear lines, small subulate spaces opposite the origin of the shorter 
rows ; apiculi sometimes many, minute, inserted close to the 
border, at wide subequal intervals. Border narrow. 
Pantocsek’s figure shows no apiculi, but in their stead small clear 
spaces surrounded by a faint circlet of markings. In the presence 
of these spaces it differs from C. intumescens , Pant. 
Habitat. — Briinn Tegel (Cleve!); Also-, Felso-Esztergaly, Kekko, 
Szakal, Szent Peter deposits (Pantocsek !). 
C. agapetosf sp. n. C. nitidulus , Grun., var.? Sell., Atl., pi. 
cxiii. fig. 18. — Diam. ’05 mm. Central space and rosette absent. 
Markings small, rounded, granular, largest towards the centre, 
decreasing outwards, on a zone adjacent to the border punctiform ; 
interspaces wide, hyaline, smaller towards the border ; rows 
obscurely radial towards the centre, becoming obviously radial near 
the border. Border narrow. 
Distinguished from C. nitidulus by the greater reduction in size 
of the markings outwards and the evident zone adjacent to the 
border. 
Habitat. — Aegina (Schmidt). 
C. exiguus , sp. n. Sch., Atl., pi. lviii. fig. 30 (no name). — Diam. 
about -04 mm. Central space distinct, rounded ; no rosette. 
Markings minute, granular ; beyond the semiradius punctiform, 
disposed at unequal intervals in evident radial straight rows ; 
interspaces largest towards the centre, hyaline ; non-apiculate. 
Border sharply defined, narrow; striae, 6 to 8 in -01 mm. 
Habitat. — Campeachy Bay (Schmidt). 
Yar. aequalis, nov. Sch., AtL, pi. lviii. fig. 31 (no name). — Diam. 
about *056 mm. Central space angular, from to ~ of diam. broad. 
Markings minute, granular or subpunctiform, 5 to 6 in - 01 mm., 
somewhat more prominent around central space ; interspaces 
narrow, hyaline. Border sharply defined, at its middle a distinct 
concentric line, hyaline. 
Habitat. — Mors deposit (Schmidt).
