Society, contributing various papers of great interest to Southport, 

 dealing largely with the Foraminifera of the district. The Society 

 was established in 1890, and the first report of its proceedings 

 contains a paper by him which is considered quite a classic on the 

 subject. This paper was so highly regarded that it was specially 

 referred to in connection with the meeting of the British Association 

 at Southport in 1903, on the committee of which Dr. Chaster played 

 a prominent part. He also contributed to the handbook prepared 

 for that occasion some important chapters dealing respectively with 

 the Protozoa-Foraminifera, Coleoptera (in conjunction with Mr. E. J. 

 Burgess Sopp, F.E.S.), and MoUusca of the Southport district. He 

 was elected President of the Society in 1897, and his Presidential 

 Address was " The Stone Age," when he exhibited many interesting 

 objects from his fine collection of Irish and other prehistoric 

 implements and weapons. 



He was an ardent microscopist, and extremely ingenious in 

 inventing little appliances for facilitating the collection and preparation 

 of specimens, and nearly always had something fresh to show us in 

 this line when we met on our annual excursions.

Manual of Conchology, Structural and Systematic : Second series. — Pul- 



monata, vols. xix. and xx. (parts 73-78), by H. A. Pilsbry, D.Sc. 



These two volumes contain monographs of the families Ole.acinidcc and Ferns- 

 sacida. The former family was monographed by Tryon in the first volume of this 

 series with a classification mainly borrowed from Pfeiffer's Nomenclator Heliceoriim 

 Vivenlium, and based upon conchological grounds. Anatomical investigations and 

 the discovery of numerous new species made a revision advisable. Many types from 

 the collection of C. B. Adams are now figured for the first time. 



The Oleacinidiz are chiefly confined to tropical America, but the single genus 

 Poiretia, typified by the well known algira Brug. , is a native of the Mediterranean 

 region. Of this genus there are three or four recent species and numerous fossil 

 ones throughout the tertiary formations of Europe, as far north as the Isle of Wight, 

 and one species occurs in the Cretaceous of Provence. Probably, therefore, the 

 recent species of Poiretia are survivors of a stock which is dying out. The family 

 is placed by Pilsbry in the superfamily Agjiathonorpha, along with Aperidce, 

 Rhytididiv, Streptaxidce, and Cireinariidce. The superfamily Agnatha (families 

 TestacellidiE, and Trigonochlamydidie') is primarily distinguished therefrom by the 

 presence of distinctly developed pedal grooves. 



As classified by Pilsbry, Oleaciiiidit contains eleven genera, viz. : Pseudosiibiditta, 

 Spiraxis, Varicella, Oieacina, Kectoleacina (n.g. for Cuban species of Streptosiyla), 

 Streptostyla, Oryzosoma (n.g. for a single species oi Streplostyla with perforate axis), 

 Strebelia, Poiretia, Salasiella, and Muglandina. The familiar name Glandina falls
