 Impulses may pass in both directions through any of the commis-

FIRST ADDITIONAL CATALOGUE OF LAND SHELLS OF JAPAN. 

 By Y. HIRASE, Kyoto, 1908. In this list of 24 pages Mr. 

 Hirase catalogues the species and varieties from Japan, the Bonin 

 and Loochoo Islands and Formosa, obtained since the publication of 

 his former list. It is interesting as showing the results of the latest 

 work on these wonderfully rich faunas. Copies of the catalogue 

 will be sent free, we believe, to those interested in the collection of 

 Japanese shells. A handsome plate illustrates various new or inter- 

 esting species.

 collection in America. The collection contains 26,000 shells, " a 

 number unexceeded, I believe, by any private shell cabinet in 

 America since the day of John Jay. While the collection is rich in 

 species representing almost every family, one naturally turns to 

 those gems of the sea, the Cypraeidse. Here we find Cyprsea 

 brodeript, the only one in America, C. nivosa, castanea, chrysalis, 

 coxenii crossei, similis, etc., etc., while species considered by many 

 rare are represented by series to show variation. There are 10 (7. 

 aurantia, 10 decipiens, 10 thersites, 7 scotti, 4 umbilicata, etc. 

 Among the Conida? is enthroned Conns gloria-maris while the rare
