148 HEMICENTETES VARIEGATUS. 



of the back (l have five specimens before me). In the 

 landrac, Buffon (supp. T. VII, p. 301, fig. LXXVI), 

 however, there is a very small whitish line on the middle 

 of the head , abrupt near the base of the crest , nor is the 

 streak on the middle of the back continuous (we possess 

 a single specimen). As there are still more differences 

 in coloration , I will describe this individual by itself 

 as a variety of the Hemicentetes variegatus. 



The foremost quills of the crest , the quills , bristles and 

 soft hairs on the head marked off by a line drawn from 

 the base of the ear to the corner of the mouth , sides 

 of the neck, posterior upper half of the sides of the 

 body , parts between the yellow streaks on the back , coverts 

 of the haunches and outside of legs, are intensely black. 

 The rest of the quills of the crest, the uninterrupted band 

 along the middle of the head and back , the two other 

 bands anteriorly curved towards the spine , the anterior 

 and posterior lower half of the sides of the body, are 

 uniformly yellow. Cheeks, chin, throat, chest, belly and 

 inside of legs covered with rather soft yellow hairs. Muzzle , 

 ears, short whiskers, hands and feet blackish. 



As to the dentition it will suffice to copy Mivart's very 

 accurate description of the teeth of Hemicentetes madagasca- 

 riensis (lege ^^ variegatus''). "The iipper incisors on each side 

 are all separated from each other and from the canine ; and 

 the first upper incisor is also separated by an interval from 

 its fellow on the opposite side. The first two incisors on 

 each side are of nearly the same size and shape. Each is 

 conical , pointed and much hooked , with a very large pos- 

 terior lobe. The third incisor is much shorter, gradually 

 broadening downwards from the socket to the distal edge. 

 The canine is shaped like the first two incisors , but rather 

 larger and with the posterior lobe relatively smaller. It 

 is very much smaller, relatively as well as absolutely than 

 in Centetes , I add "and in Hemicentetes madagascariensis'". — 

 The first premolar, in shape and size, is very much like 

 the canine , though separated from the latter by an inter-
