12 THE JSAUTILUS. 



and the Cyrenidce (Corbiculidw). 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 Unionidce 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 Ccecum (C. ampntatvmi) from Sydney 

 Harbor, Australia, and gives an interesting paper on Gundlachia. 

 The latter we will reprint in a future number. 



LISTE SYNONYMIQUE ET BIBLIOGEAPHIQUE DBS MOLLUSQUES 

 Terrestres el Fhiviatiles de la Nouvelle'Zelande. 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 HUTTON, 

 SUTER, HEDLEY, PILSBRY and others, is a complete epitome of 

 progress to this time. It is prefaced by a note from the experienced 

 pen of CROSSE, contains copious references, and a plate illustrating 

 some interesting forms. The work is well-done and of great utility. 



MONOGRAPH OF THE GENUS STROPHE, by C. J. Mayuard (Cou- 

 trib. to Science II, Nos. 3 and 4). Mr. Maynard prefaces his de- 

 scriptions by some interesting observations, inter alia, that Slrophia 

 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 Multostrophia, 

 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.
