122 MAMMALS OF THE 



nately therefore has the priority to the loug-knowa name 

 leptonyx given in 1824 by Horsfield to the same animal, 

 the so-called clawless otter from Java. As the description 

 of V. Wurmb's otter as well as Illiger's name for that animal 

 are to be found in rather unknown or difficultly accessible 

 books, it may perhaps bear some interest to give the full 

 and exact titles of the mentioned books , the more as 

 Thomas himself is not quite correct in his quotation and as 

 Blanford in his » Fauna of British India, Mammalia, 1888 — 

 91" though accepting Thomas' interpretation commits an- 

 other error (Illiger 1815 instead of llliger 1811). 



Baron F. v. Wurmb described the » Grijze otter, die om- 

 streeks Batavia gevonden wordt" in the » Verhandelingen 

 van het Bataviaasch Genootschap der Konsten en Weten- 

 schappen", 1784, Vol. 2, p. 456 (not 1780, see Thomas). 

 It is very likely that Thomas never saw the named volume 

 as he quotes Srii edition, published 1826. 



Illiger's paper, vorgelesen den 28 Februar 1811 has been 

 published in » Abhandlungen der königlichen Akademie der 

 Wissenschaften in Berlin, Abhandlungen der physikalischeu 

 Klasse der Königlich-Preussischen Akademie der Wissen- 

 schaften aus den Jahren 1804—11, Berlin, 1815"; the 

 full title is: »Ueberblick der Siiugethiere nach ihrer Ver- 

 theilung über die Welttheile", p.p. 39-159.
