Fischer, P. — Note sur 1'anatomie de X Helix dictyodes, Pfeiff- 

 er (Note on the anatomy of Helix diclyodes), pp. 273 — 276. 



This New Caledonian species proves to be a true Helix. The 

 jaw is smooth, without median projection. The formula of the 

 lingual dentition is 36-1-36, the teeth are all tricuspid^ The re-

 Figs. 3 — 6 of Plate XIV. illustrate this paper. 



Fischer, P. — Sur les Pellicula depressa, Rang, et appendiculata, 

 Pfeiffer (On Pellicula depressa and appendiculata), pp. 276 — 277. 



These two species prove to be distinct, Dr. Fischer describes 

 and figures the shell of P. appendiculata (PL xiv. fig. i),and of 

 P. depressa (fig. 2), and describes the jaw and dentition of the 

 latter species, those of the former having been described in the 

 previous vol., p. 137. Both species are arboreal, and inhabit 

 Guadeloupe.
