ADDENDA. 



Since publishing my first article on Japanese and Loo-Choo shells, 

 Mr. Pilsbiy has sent me a reprint of a paper published by him in the 

 Proceedings of the Academy of Natural Sciences, Philadelphia, for 

 1899, which I had not seen when going to press. As two of the 

 species described by me as new are published in Mr. Pilsbry's article, 

 which was issued February 12th, 1900, my names become synonyms. 

 They are: Eulota (Plectotropis) Hirasei (ante, p. 10, pi. ii, figs. 4-7), 

 which becomes Eulota cavicottis, Pils. (loc. cit., p. 527, pi. xxi, 

 figs. 11-13). Mr. Pilsbry makes this species the type of a new 

 subgenus, Ccelorus : Eulota (JEgisfa) Awajiensis (ante, p. 11, pi. ii, 

 figs. 8-10) becomes Eulota {JEgista) aperta, Pils. (loc. cit., p. 527, 

 pi. xxi, figs. 7-9). Toyonishikami, province Nagato. 



In the same article (p. 526) Mr. Pilsbry changes Eulota lata, Gld., 

 to E. Gainesi, on account of Helix lata] Pfr., an earlier name than
