 ball.

Sp. Erinaceus europceus L., BUFF. vm. PI. 6, GUER. Iconogr., Mammif. PI. 

 10, fig. i ; the Jiedgehog, le herisson, der I gel; a nocturnal animal, living 

 on mice and insects, torpid in winter. Compare J. J. WETTER Erinacei 

 europcei Anatome, c. 4 tab. sen. Gottingae, 1818, Svo; M. SEUBERT Sym- 

 bolce ad Erinacei europcei Anatomen; accedunt Tab. 2 lith. Bonnae, 1841, 

 4to. The rolling up is effected by a strong cuticular muscle with thick 

 margins, which is able to enclose the body like a sac. Compare F. HIMLY 

 Ueber das Zusammenkugeln des Igels, Braunschweig, 1801, 4to. 



Erinaceus auritus PALL., S. G. GMELIN Nov. Comm. Petrop. xiv. i, p. 

 519, PALLAS, ibid. p. 573, SCHREB. Saugth. Tab. 163; in Southern "Russia, 

 Siberia and Tartary, at the Baikal sea, &c. A species occurring in Egypt 

 and formerly confounded with the preceding is Erinaceus brachydactylus 

 WAGN., Erinaceus libycus EHRENB. 



Compare on the rest of the species, besides WAGNER, SUNDEVALL Ofver- 

 sigt of sldgtet Erinaceus, Kongl. Akad. Vetensk. Handl. 1841, pp. 215 239. 

 Erinaceus heterodaciylus SUNDEV. from Sennaar, differs by a small rudi- 

 ment of thumb on the hind feet, without claw. 



With Erinaceus ought to be placed, though commonly referred to Cen- 

 tetes, the Tendrac of BUFFON, xn. PI. 57, Centetes spinosus DESMAR., 

 named improperly by ScHREBER and GMELIN Erinaceus setosus. ISID. 

 GEOFFROY SAINT-HILAIRE forms from it his genus Ericulus, which in that 

 case should be placed between Centetes and Erinaceus. With the same 



entire number of teeth there are incisors present. See ISID. GEOFFR. in 



GUER. Magas. de Zool. 1839, Mammif. PI. i 4. W. C. L. MARTIN 

 afterwards distinguished another genus, which he named Echinops, and 

 which, if it be sufficiently distinct from Ericulus, would seem to have one 

 molar less on each side in the upper and lower jaw. Sp. Echinops Telfairi 

 MARTIN, Trans, of the Zool. Soc. n. pp. 249 256, PI. 46. I have not 

 myself investigated these animals.
