Ten new and four known taxa of the diatom genus Actinocyclus are described, illustrated, and (or) noted from middle Miocene lake deposits in the Western United States. This part of the sea is inhabited by the greatest number of unique Caspian species, which descend from ancient inhabitants of the Thetis. This is the deepest part of the sea, which in the southern basin exceeds 1 km. This part of the Caspian has never completely dried up, independently of climate changes that occurred in past geological epochs.

The centric diatom class comprises nine major groups, recognized now as subclasses. Some examples are the discoid subclass, which includes Thalassiosira, a colonial diatom that extrudes threads, called setae, of chitin, which hold individual diatoms together in chains; the solenoids, elongate diatoms, cylindrical or subcylindrical in shape; the box-shaped ­biddulphioids, most with horns or.

Patrick and Reimer’s monographs, The Diatoms of the United States (, ), treat many araphid and raphid diatom genera.

Journey through cyberspace to Fossil Valley, a world-famous desert district situated in Nevada's Great Basin geomorphic province that contains the most complete, diverse, terrestrial (land-laid) fossil record of Miocene life yet discovered in North America--and perhaps the world, as a matter of fact--a genuinely spectacular paleontological place that produces from what earth scientists call.

Much of the work focuses on diatom research including new taxonomic descriptions (a new genus Hyalosigma, fourteen new diatom species, and one new combination), discussion of evolutionary patterns, ecology of freshwater species and the use of diatoms in bioassessment.

However, the systematics and physiology of some other algal groups are also. Microcoleus vaginatus (Fig. ) makes up over 90% of cryptobiotic crusts in the arid soil of the Colorado Plateau in the United States (Belnap and Gardner, ).

Filaments of M. vaginatus are surrounded by thick mucilaginous sheaths that can absorb eight times their weight in water, increasing the water capacity of sandy soils.

Such is the description given by Dr. Carpenter of the Amœba and its allies. The Amœba princeps, which is the type of the naked group, fig. 86, is merely a shapeless mass of semi-fluid sarcode, coated by a soft, pellucid and highly contractile film, called diaphane by Mr. Carter, and in many forms of Amœba the whole is inclosed in a transparent covering.
