144 SETIGEB SETOSUS. 



Our Museum contains : ten — nine stuffed and one al- 

 coholic — specimens from different parts of Madagascar, 

 viz : from Tintingue , Tamatave , Mouroundava and Mahambo , 

 collected by Lantz , v. Dam and Audebert , and nine skulls. 



B. Centetes, Illiger — 1811. 

 I. ^-^. c. ~. P. M. -^ -. M. ^. 



3—3 1—1 3—3 3—3 



Resembles externally young Porcupines. No streaks nor 

 bands on back or head. Crest well developed. 



2. Centetes ecaudatus , Schreber — 1778. 



Muzzle much more enlarged than in Setiger setosus , 

 therefore the head attains nearly half the length of the 

 body — in Setiger setosus about one fourth. 



Upperparts of head , cheeks , sides of neck , fore-part of 

 back and outside of thighs closely covered with harsh 

 quills, forming on the hind part of the head between the 

 ears an elevated crest. Quills white ■^) or yellowish white 

 with a rather small brown or reddish-brown subtermiual 

 ring. Some quills are entirely white. Hind part ot back , 

 sides of body and outside of legs furnished with longer 

 flexible bristles-like quills, on the hindmost part of the back 

 gradually passing to very elongated — in the largest 

 individual before me they measure 65 m. m. — undulating- 

 bristles which are overhanging the rump and tail. These 

 bristle-like quills and bristles are white or yellowish white 

 colored with a brown or reddish-brown subterminal ring , 

 the extent of the two colors being in proportion to the 

 length of the coverings. A few among them are entirely 

 brown. In the young ones — measuring about 15 c. m. — 

 there are a few short pure white quills between the long- 

 bristles and also some entirely brown bristles, much 

 longer than the other ones. 



1) The specimens with very long pure white points to the quills and bristles 

 belong to Centetes armatus. Is. Geoffroy St. Hilaire, (see o. c. p. 31, pi. 2).
