and the Cyrenide (Corbiculide). Like those which have preceded, 
the execution of the plates is superb, and the text is prepared with 
the attention to detail and accuracy characteristic of its authors. 
Many species of Unionide described by Morelet are herein for the 
first time illustrated, as well as those of Crosse and Fischer. This 
part completes the work, but one more will be issued containing 
additions to the fauna, being supplementary to the entire work. 
In the Proc. Linn. Soc. N. S. Wales, VIII, Mr. Charles Hedley 
describes a new species of Cecum (C0. amputatum) from Sydney 
Harbor, Australia, and gives an interesting paper on Gundlachia. 
The latter we will reprint in a future number. 
Liste SyYNONYMIQUE ET BIBLIOGRAPHIQUE DES MOLLUSQUES 
Terrestres et Fluviatiles de la Nouvelle Zélande. By Henry Suter, 
with preliminary note on the affinities of the New Zealand mollusk 
fauna by H. Crosse. The land mollusk fauna of New Zealand has 
received much careful study during the past few years, and this cat- 
alogue of 86 pages, embodying the results of the studies of Hurron, 
Surer, Hepiery, Piispry and others, is a complete epitome of 
progress to this time. It is prefaced by a note from the experienced 
pen of CRossk, contains copious references, and a plate illustrating 
some interesting forms. The work is well-done and of great utility. 
MonoGRAPH OF THE GENus Srropuia, by C. J. Maynard (Con- 
trib. to Science II, Nos. 3 and 4). Mr. Maynard prefaces his de- 
scriptions by some interesting observations, inter alia, that Strophia 
is found in the Bahamas only on islands and keys where palms grow, 
and does not occur on any that are not, or have not been inhabited 
by man. The descriptions of many new species follow. The care- 
ful and exact record of localities for each species and subspecies, is 
a most commendable feature of the work. There can be no doubt 
that the forms are in many instances extremely local in distribution, 
a fact which we owe to Maynard’s researches. The localities given 
in former works on the genus are in a large number of cases wholly 
untrustworthy. Maynard proposes a new subgenus Mudtostrophia, 
type S. eximea n. sp., for shells with small Maynardia-like tooth and 
very fine striations. Among the figures we notice that that of S. 
cinerea (p. 119) has the axial lamella on the outer lip, doubtless an 
error of the engraver.
