Recensionen. 



R. Lydekker (Annais and Magazine of Natural History) : Stupendous task . . . 

 All naturalists owe Dr. T. a debt of gratitude, the extent of 

 which is almost impossible to express in words . . . Dr. T. must 

 possess patience and industry far above the average, while 

 he has also the technical knowledge of his subject which 

 raises the work toamuch higher level thantheeffortsofthe 

 more Compiler and bibliographer. In the name of ourfellow 

 students we beg to tender to the learned author our most 

 hearty congratulations and thanks. 



Dr. C. H. M e r r i a m ('Science') : Of such great practical utility, that 

 foryears to come every student of livingor fossil mammals 

 must keep a copy at his elbow and will owe to its author a debt 

 of gratitude. 



Dr. J. A. Allen ('The American Naturalist'): Mammalogists owe to Dr. T. a 

 largedebt of gratitude... Aworkwhichwill prove an enduring 

 monument to the patience, industry and scientific acumen of 

 its author. . . The labor involved in this compilationisthus 

 beyond easy conception, and its value to fellow-workers is 

 inestimable. 



M. R. 0. Thomas ('Natural Science') : Got up by Messrs. Friedländer in a 

 superior style . . . Will have to be in the library of every 

 mammalogistand will be of more use than the great majority 

 of more portentious works. 



M. Cossmann ('Revue critique de Paleozoologie'): Ce catalogue comble une 

 reelle lacune... Nous n'avons pas ä faire l'eloge de notre 

 savantcollaborateur, dont la competence est bien connue. 



Revue Scientifique:Extreniement complet,et tout ä fait remar- 

 quable par l'abondance et la richesse des informations... II a 

 fallu une patience et un labeur vraiment formidables . .. Tous 

 les hommes de science doivent etre recon nai ssants ä M. 

 Trouessart de sa hardie et laborieuse initiative. 



Natur: Eine ausserordentlich verdienstvolle Arbeit, die durch 

 Berücksichtigung der fossilen Arten einen doppelten Wert 

 gewinnt. 



Prof. H. Nitsche ('Litterarisches Centraiblatt'): Die mühsame Arbeit ist 

 höchst dankenswert und wird allen nachfolgenden Bear- 

 beitern einschlägiger Themata ihre Untersuchungen wesent- 

 licherleichtern. 



B. Langkavel ('Zoologisches Centralblatt') : Ein unentbehrliches Hand- 

 und Nachschlagebuch. 



R. Lydekker (Nature) : We have much pleasure in congratulating the author on the com- 

 pletion of the first quinquennial Supplement, whereby an absolutely invaluable work 

 is brought well up to date. — As usual, Dr. Trouessart's work a p - 

 pearsto be exceedingly accurate; as to itsvalue to students 

 nowords of ours are necessary. It is indispensable and unique. 



Prof. Dr. F. Römer (Zoolog. Centralblatt): Jeder, der sich an den Gebrauch des Troues- 



sart'schen Kataloges gewöhnt hat, wird das Erscheinen eines Nachtrages mit Freuden 

 begrüssen.
