agreeing with it from the Laos Mts. (Coll. Moubot),* show that S. p/iai/rci is 

 Imt little more than a dwarf form of S. alboniger, although it is no doubt just 

 siiecifically distinct. The really nearest ally of S. ercretti is probably S.aurantiacus 

 AVagn.jt of which JentinkJ has figured the skull of a topotype. Judging by this 

 figure, S. everetti shares the general form of the skiUl and the postero-superiorly ex- 

 ])anded bullae, but is decidedly larger, and has stouter and more directly transverse 

 postorbital processes. Nor does the coloration of the tail agree with Wagner's 

 descrijitiou. 



The two animals formerly described as new both belonging to genera in which 

 species had already been named after Mr. Everett, Mr. Hartert and 1 were unable 

 to signify in this way our recognition of the signal services to science rendered by 

 his exploration of the zoologically unknown Natunas. It is therefore with great 

 pleasure that 1 now dedicate this beautiful .Vatunu s(juirri,l in his honour.
