The gastropod genusThalassocyonBarnard, 1960

The Heinz fellowships 1960-80.

This paper celebrates a 25th birthday, a record of learning and teaching across the Commonwealth. It began in 1959, when Philip Evans (secretary, British Paediatric Association 1954-59) and Reginald Lightwood (Head of University Department of Paediatrics, St Mary's Medical School, London), convinced that paediatric teaching exchanges would improve child health within the Commonwealth, sought th...

The Gastropod Fauna along the Bushehr Province Intertidal Zone of the Persian Gulf

The gastropod fauna of Bushehr Province intertidal zone at the Persian Gulf were identified following an investigation starting spring 2009 until winter 2011. Bushehr coastline is a 673.62 km stretch along the northern and northeastern coast of the Persian Gulf. Sampling took place from Deylam at Bushehr-Khuzestan borderlines, extending southeastward through Genaveh, Bushehr, Bolkheyr, Kab...

The Gastropod Genus Thatcheria and Its Relationships

Gangliogenesis in the prosobranch gastropod Ilyanassa obsoleta.

We determined that the larval nervous system of Ilyanassa obsoleta contains paired cerebral, pleural, pedal, buccal and intestinal ganglia and unpaired apical, osphradial, and visceral ganglia. We used a modified form of NADPH diaphorase histochemistry to compare the neuroanatomy of precompetent (including specimens 6, 8, and 12 days after hatching), competent, and metamorphosing larvae with po...

The Mechanism of Locomotion in Gastropod Molluscs

Whereas the broad outline of the mechanical events of locomotion can in most animals be readily visualized, the mechanism of propulsion in gastropods is less easily observed. Since the seventeenth century (Lister, 1694) a great deal of attention has been paid to this problem and a wealth of suggestions has been forthcoming; there is, however, a significant absence of convincing experimental dat...
