not to the broad-headed race represented in Forsyth Ma- 

 jor's colleetions. 



As soon as the present writer had had the opportunity of 

 observing the great difference in size and shape of the skulls 

 collected by Major, and by Kaudern it became apparent 

 to me that they represented two different geographic sub- 

 species. I suspected also that the smaller and narrow-headed 

 race would be found to inhabit the western part of the 

 isJand which is a comparatively more dry and open co- 

 untry, while the larger, broadheaded race ought to inhabit 

 the more humid eastern forest region. This was already 

 hinted at by the statements about the localities where the 

 specimens had been collected. Forsyth Major says explicitly 

 that his specimens were »from the Upper Forest Region» 

 (1. c. p. 364). 



To obtain information about the habitat of the smaller 

 and narrow-headed race I asked Dr. Kaudern to tell me 

 what he knew about the Bush Pigs of Madagascar. He then 

 kindly gave me the following communication which I take the 

 pleasure of quoting in translation. It will be seen from the 

 same that it fuUy confirms my view. Dr. Kaudern writes: 



»During my sejourn 1906 — 1907 in Northwestern Mada- 

 gascar (province Bouéni) the natives told me that they dis- 

 cerned two kinds of Bush Pig which were called by them 

 resp. »Lambo mena» (Lambo = pig; mena = red), and 

 Lambo ho va (ho va after the people with thatname), »Lambo 

 mena» was said to be smaller, and it inhabits the western 

 dryer part of the country while Lambo hova» is distributed 

 över the eastern part with a tropically moist climate. The 

 name of the western form indicates that it is more reddish 

 brown than the eastern. That two different races should be 

 found on Madagascar appears to me quite probable, because 

 the conditions of life must be positively different in a country 

 where the annual quantity of rain amonnts to 3 m. and 

 where it rains during the summer as well as during the win- 

 ter without any pronounced dry season, and in another 

 country with the annual amount of rain only 1 m., and with 

 a dry season continued through several months. According 

 to the statements of the natives, other mammals as well, that 

 are distributed över the whole island as CeyUetes, Cryptoprocta 

 and Eiipleres, differ in the western and eastern parts. Gran-
