Microstructure and crystallographic texture data in modern giant clam shells ( and ).

This article provides novel data on the microstructure and crystallographic texture of modern giant clam shells ( and ) from the Coral Triangle region of northeast Borneo. Giant clams have two aragonitic shell layers-the inner and outer shell layer. This dataset focuses on the inner shell layer as this is well preserved and not affected by diagenetic alteration.

A further review of European Magelonidae (Annelida), including descriptions of Magelona equilamellae and Magelona filiformis.

Following on from the partial review of European Magelonidae by Fiege et al. (2000), a dichotomous identification key, a table of characters and images of all nine known European magelonid species are provided. Magelona equilamellae is redescribed highlighting several features not reported originally by Harmelin.

Redescription of Magelona minuta Eliason, 1962 (Annelida), with discussions on the validity of Magelona filiformis minuta.

Since Magelona minuta was described in 1962 our understanding of the key features required to distinguish between magelonid species has increased. The original description contains only four illustrations and vital information on many key characters is not included. This re-assessment of the holotype and material from the type locality includes several features not previously described, specifically related to thoracic and abdominal lamellae.
