Dr. L. Pfeiffer has published volumes V. and VI. of his 
excellent monograph of Heliceae, the subject being treated in the 
same manner as in the previous volumes. Original diagnoses 
are given of the species known to the author from autopsy ; 
with regard to those not seen by him (and we regret to say 
their number is large) the descriptions given by their authors 
are reproduced without alteration j also new descriptions by 
other conchologists, given for species described in the previous 
volumes, are reproduced in notes, so that the student may as 
far as possible be informed of every advance and difference of 
opinion. The literature published since the issue of the fourth 
volume (1859) is added to each si)ecies, very conscientiously and 
nearly completely, only a few malacological works not having 
been accessible to the author. The systematic arrangement is 
essentially the same as in the previous volumes ; only the two 
genera Testacella (Cuv.) and Gceotis (Shuttl.) have been added. 
The genera Helix and Bidimus are maintained in too wide a 
sense, notwithstanding the differences in jaw and radula pointed 
out by various authors; but the natural groups or genera to 
which the several species have been referred (especially in the 
second edition of Alberses Gleliceen’) are indicated by (juotations. 
Vol. V. eontains : — Testacella, 10 sp. ; Daudehardia, 11 sp.; 
Gatotis, 3 sp.; Viirina, 105 sp. ; Simpulopsis, 18 sp. ; Succinea, 
177 sp. ; Phy sella (^^v. = Strebelia, Crosse), 1 sp. ; Helix, 2905 
sp. arranged under 136 paragraphs, the chief divisions being- 
taken from the peristome ; Boysia (Pffr.), 1 sp. ; Plectostoma 
(A. Adams), 1 sp. [this genus is now known to be opercu- 
lated, and consequently does not belong to this family] ; Hypse- 
lostoma, 2 sp. ; Anostoma, 5 sp. ; Tomigerus, 5 sp. ; Strejjtaxis, 
67 sp. ; Ennea, 39 sp. ; Streptostele, 4 sp.
