19G J. Anderson — On the Indian Species [No. 4, 



From the facts to be hereafter stated there can be no doubt but that 

 these two species, E. micropus and JE. p ictus are perfectly distinct from, each 

 other, and from any other species of Indian hedgehog ever described. 



It would also appear from what I have stated under E. grayi^ that it is 

 a well-defined species, and that it is probably the hedgehog which was 

 figured by Gray from the Doab as J^. collaris, but which was never describ- 

 ed, and also that Dr. Jerdon was correct in regarding E. spatangus as the 

 young of JE. grayi, the latter term being the one that should be accepted 

 for the species. 



Dr. Gunther, to whom I am indebted for comparing the hedgehogs in 

 the British Museum with certain specimens forwarded 'from the Indian 

 Museum, informed me that the true relations of E. mentalis cannot be pro- 

 perly determined. I regret, however, that having mislaid Dr. Gunther's 

 notes, I am unable to give the details of his comparisons. 



I have personally examined the type of E. nudiventris which is a very 

 young exaniple of E. micropus. 



Besides these three species, E. micropus, E. pictus, and E. grayi, the 

 materials which have passed under my observation* have yielded two 

 other apparently distinct species of hedgehog from Western India, and 

 which I propose to name respectively E. jerdoni, and E. hlanfordi, the 

 distinctive characters of which are indicated hereafter. We have thus five 

 species of hedgehog in India, three of which are forms which were unknown 

 when Fitzingerf published his compilation on the Erinaceidce in which he 

 recognized E. grayi, E. collar is, E. spatangus, E. mentalis, E. nudiventris 

 and E. micropus, referring them all to a trivial sub-genus Semiechinus. 



The hedgehogs of India are referable to two distinct groups, based on 

 the characters of the dentition. E. micropus and E. pictus resemble each 

 other in the following dental detail, wherein they differ from the other Indian 

 hedgehogs, but whether any of the African forms are like them in this re- 

 spect I am unable to say. The character I refer to is this, that the second 

 upper premolar has a simple crown and only one fang, whereas E. grayi, E^ 

 jerdoni, E. hlanfordi, E. macracanthus, E. niger,% E. megalotis, E. auritus 

 E. allulus, and E. europceus, have the same tooth large with a compound 

 crown and with 3 fangs. In both the species, the second upper premolar is 

 very small and somewhat external to the line of the other teeth. In E. 

 pictus, the tooth would appear to be generally present throughout life, and it 

 is larger than in E. micropus, in which it seems to be generally lost at an 

 early age. In hedgehogs with a compound second premolar, the tooth is 



* I am specially indebted to Mr. W. T. Blanford for his having placed his fine 

 series of Indian hedgehogs, preserved in alcohol, at my disposal for examination.
