Text-Fig. 13 Dasmosmilia kochii ( Pratz, 1910) . A, type specimen as figured in Pratz (1910) as Turbinolia kochii Pratz, 1910 , Upper Campanian of Serbia, cross view; B, NMNH, Coates coll., sample no.: J-71-16 Aa , Upper Maastrichtian of Jamaica ; C, NMNH, Coates coll., sample no. J-71-16AbC, Upper Maastrichtian of Jamaica ; scale bar: 4 mm

Dimensions. d (min)= 5–20 mm; d (max)= 5–21 mm; d (min)/d (max)=0.83–1; s=up to 100; h=up to 23 mm.

Description. Solitary, turbinate-trochoid; circular to slightly elliptical in outline; costosepta arranged in 5 complete cycles in adult specimens, alternating in thickness, unequal in length; in coralla of a diameter of around 5–7 mm, 48 septa corresponding to 4 complete cycles are developed; columella is irregularly spongytrabecular and fused with trabecular prolongations of inner ends of septa of the first two sets; wall parathecal to septoparathecal; endothecal dissepiments sparse, mainly occurring in the lower part of the corallum; relicts of an epithecal wall present.

Remarks. The specimens from Jamaica (Figs 13B and C) and from Serbia (Fruska Gora) have smaller dimensions than the specimens of the type series of Dasmosmilia reesidei . However, according to their septa development and their morphological appearance it is suggested that they represent juvenile stages of the species D. kochii .

Type locality of species. Upper Campanian of Serbia (Fruska Gora) .

Distribution. Upper Campanian of Serbia (Fruska Gora), Maastrichtian of the USA (see Wells 1933: Navarro Formation, Texas; see Sohl, 1987: Alabama, Mississippi, Texas), Upper Maastrichtian of Jamaica (this paper).

New Material. Upper Maastrichtian of Jamaica, NMNH, Coates coll., sample nos.: J-71-16Aa; J-71- 16Ab (=Shaw Castle, Maldon Formation).
