Attention is drawn to the one side remaining of a nineteenth-century correspondence addressed to Alexander Somerville that is housed in the archives of the Scottish Association for Marine Science at Oban, concerning conchological matters. Previously unstudied letters from James Thomas Marshall shed new light on the practicalities of offshore dredging by nineteenth-century naturalists in the Clyde Sea Area; on personalities within conchology; on the controversies that raged among the conchological community about the production of an agreed list of British molluscan species and on the tensions between conchology and malacology. In particular, the criticism of Canon A. E. Norman's ideas regarding taxonomic revision of J. G. Jeffreys's British conchology, as expressed by Marshall, are highlighted.

Abstract Bed-by-bed sampling of twelve Barremian sections in southeastern France from pelagic basin (Vocontian Basin) to neritic platforms (Arc of Castellane, Arc of Nice and Provencal Domain) has enabled the collection of isochronous samples of the ammonite genus Gassendiceras. Three poorly known species of the Toxancyloceras vandenheckei Zone (Upper Barremian) are revised: G. alpinum, G. multicostatum and G. hoheneggeri; two new species are described (G. rebouleti nov. sp. and G. bosellii nov. sp.). The intraspecific variability of particular species was recognised. This variability is between slender peramorphic and robust paedomorphic extreme morphologies, with the presence of all intermediates.

The paper provides a brief conspectus of the system of morphological generic groups, elaborated earlier by the author basing on the total taxonomic revision of Palaearctic mealybugs. Here the system is complemented by the analysis of all 249 genera of the world fauna. Borders of two generic groups are reconsidered and two else groups (with mainly Oriental and Australasian genera) are included in the system. Main taxonomic characters of generic rank are discussed and illustrated.

Distribution Data

A worldwide taxonomic revision of the species belonging to the moss genus Chionoloma Dixon (Pottiaceae) is here presented. Our work is based on the morphological analysis of more than 2600 specimens deposited in different herbaria or collected during field trips. A total of 131 names were found and their nomenclatural types were examined, resulting in the lectotypification of 45 names. It is concluded that Chionoloma is composed of 22 species and one variety, seven of them are here newly combined (C. circinatum (Besch.) M. Alonso, M. J. Cano & J. A. Jiménez; C. cylindrotheca (Mitt.) M. Alonso, M. J. Cano & J. A. Jiménez; C. hyalinoblastum (Broth.) M. Alonso, M. J. Cano & J. A. Jiménez; C. melanostomum (Mitt.) M. Alonso, M. J. Cano & J. A. Jiménez; C. orthodontum (Müll. Hal.) M. Alonso, M. J. Cano & J. A. Jiménez; C. sarawakense (Dixon) M. Alonso, M. J. Cano & J. A. Jiménez; and C. stenocarpum (Thér) M. Alonso, M. J. Cano & J. A. Jiménez). Moreover, 42 names are newly synonymized and a total of 74 new records for various countries are reported. Keys, descriptions, illustrations, photographs, and distribution data of each species are provided.
