Evolution of Optical Design in the Malacostraca (Crustacea)
2002How much can compound eye structure and optical design tell us about the phylogenetic relationships and evolution of the carriers of the compound eyes, in our case the crustaceans? To answer this question, it is necessary to distinguish between compound eye morphology and the cellular composition of the ommatidia on the one hand, and eye physiology and

Notes on Paleozoic Malacostraca of USSR. Pygocephalomorpha
International Geology Review, 1967The classification of higher crustacea is reviewed and the family Tealliocaridae is considered to be a synonym of Pygocephalidae of the order PygocephalOmorpha. Hitherto only two representatives of Paleozoic higher crustacea have been known from the USSR.

XC.—The Malacostraca: Their origin, relationships and Phylogeny
Annals and Magazine of Natural History, 1955Abstract This paper is based on the morphology of certain Cambrian Trilobites. These are much the most primitive Arthropods known, much more so than any Crustacea. Trilobites constitute the most primitive Arthropod Class, and they alone suggest the stages of origin of the Arthropod—the prot-Arthropod with simple eyes and the deut-Arthropod with ...

AbstractThe central nervous system (CNS) of malacostracan crustaceans (e.g. shrimp, crayfish, lobsters, crabs, stomatopods, isopods, amphipods) is an arthropod-typical ventral nerve cord with fused anterior ganglia forming a brain and a suboesophageal ganglion.
