"Rotalia freyeri Tab III, Fig.6,7

Test strongly conically arched on one side, on the other side weakly convex, keeled, in adult specimens more than 3 whorls, in the last one 10 chambers. The rim is only a bit rounded out in the last chambers of adult specimens. The pores are less dense than in R. veneta and are abit larger, 0.xxx in diameter. The last chambers of adult specimens show on the upper side of the test along the sutures groups of irregular little bosses.The opening of the last chamber is round and is placed in the middle above the keel of the penultimate whorl. Tests are right or left coiled. The colour of the animal is yellow-brown. The diameter of the proloculus is 0.xx, the diameter of the test is 0.xx. I found this species in jars with sand sampled from a little rock island near Ancona,south of the port. It is rare. One or two chambers were colourless in all individuals, The pseudopodes emerged like in R. veneta from the opening of the last chamber or from the fine pores distributed all over the test. Fig 6 represents a right coiled specimen with pseudopodes emerging from the last two chambers, seen from above, Fig. 7 is another specimen, left coiled, front view, showing the opening in the last chamber. Enlargement: 72x
