Discusses the characters and affinities of the family of the Scalidae. 

 Takes up the consideration of the Cretaceous species of Scalaria (in- 

 cluding the subgenus Opalia), and describes the new species S. Queenii, 

 S. Meyeri, S. ischyra, S. Fittoni, S. climaspira, S. cerithioides, and S. 

 Tcalospira. Accepts Seeley's genus Funis, and refers to it, as new 

 species, F. crebricostatus and F. cancellatus. The genus Pyrgiscus, 

 Philippi, is likewise accepted, P. Gaultinus and P. Woodwardi being 

 described as new species, and the Cerithium tenuistriatum of Seeley 

 being referred here. The Scalaria angularis of Seeley is referred to 

 Brachystoma, a new subgenus of Aporrhais. Deals with the genus 

 Rissoina, and, in addition to R. incerta, D'Orb., describes R. Sowerbii 

 as new. All the new species are British. H. A. N.
