sists in living in Portugal, " malgre les dents " of the Re\-ue 

 Zoologique; Hydrobia gibba, Drap., is guilty of similar impertin- 

 ence; Unio IFokci/c/ii and t/! /m//V should be struck out of the list, 

 the former being exotic (probably Australian), and the latter a young 

 U. margaritifer. 34 species are added to the Portuguese list ; the 

 most interesting are Liinax Lusitanus and Bocagei, Silva, Helix 

 ciliata, A-^enetz, U. circuniscssa, Shuttl. (previously only found in the 

 Canaries)^jP//'/>(7 substriala, Jeffr., Clausilia Mouiziana, Lowe, Cydas 

 Lusitanica, n. sp. The fauna of Portugal now includes 151 extra- 

 marine Mollusca. The peculiar species are rather icw, but the 

 fauna is of interest as showing which species extend to the extreme 

 west of the European continent. 



Pettard. — Notice sur les Coquiiles terrestres de Tasmanie 

 (The land shells of Tasmania), pp. 261 — 263. 



A short but interesting note. Tasmania is much richer in 

 proportion than Australia in land shells. 2 species of Bulimus. 3 

 of Suca'jiea, 2 of Truncatella^ 3 of Vitrina, and 122 of Helix are 

 already known. Only 3 species (H. Alexandrce, Mortii and 

 Sydjieyensis) are common to Australia, and from their habitats — 

 gardens, cellars, sewers, etc. — have probably been introduced 

 either into Australia or Tasmania. In Tasmania itself the 

 species are very localised, only two being common to the North 

 and South. Hence further discoveries may be confidently anti- 

 cipated. 



Fischer. — Note sur les dents inte'rieures de la coquille de 

 \ Helix polygyrafa, Born. (The internal teeth of H. polygyraia)^ 

 pp. 263—267. 



Adult shells have a row of 5 teeth (two parietal and three 

 palatal), inside the last whorl at 40 to 80 millimetres from the 

 aperture, and, sometimes, 40 to 50 millimetres beyond, traces of 

 a second row. Young shells bear traces of three rows, the
