The Proposal of Ebenezer Howardsal lamina and distinct cell types named: columnar cells, glial cells, tuft cells, and gland cells. The cell types appear in all of the studied samples, apart from the tuft cell, which has been observed only in the funnel epidermis up to now. A description of their fine structure is given and a func

The Proposal of Ebenezer Howardhesis is localized in a special type of cell which is cytomorphologically similar in both genera. In . these haemocyanin-producing cells are located in the branchial gland (polygonal cells) and also in the midgut gland (triangular replacement cells), especially in newly hatched animals. In . these c

The Proposal of Ebenezer Howard the Crimean Peninsula (Black Sea). The shell structure was studied with SEM. The prismatic wall of the protoconch wedges out near the mural part of the first septum, a short distance after the closing membrane. The prismatic protoconch wall consists of sublayers. In the extremely thin shell wall at

In the Lytoceratina and Ammonitina, such crystals are also cyclically twinned, forming a pseudohexagonal trilling. The first-order needle-like crystals are arranged in longitudi
