only two falše molars on each side of the upper jaw. With this 

 exception the development of the whole of the teeth appears to be 

 complete. 



The small size of the Er. Spatangus, its elongated form, the 

 regular disposition of its spines, the more rounded form of its ears, 

 and the comparative length of its hinder foot, distinguish it from 

 the other species exhibited, which Mr. Gray was disposed to consi- 

 der as the Ėr. collaris ūgared in the 'Illustrations of Indian Zoology,' 

 but which Mr. Bennett rather regarded as a new species, it being 

 deštitute of a vvhite collar, and differing in other particulars from 

 the figure referred to. Mr. Bennett accordingly characterized it 

 as the 



Erinaceus Grayi. Er. auriculis longis: spinis irregulariter in- 

 tertextis, Jlavescenti apicnlatis nigrescentigue amtulatis ; capite 



frisescenti-brunneo ; auriculis mentogue usque ad auriculas al- 

 escentibus ; gastrao pedibusųue dilute brunneis.

Jun. (edentulus). Spinis haud Jlavescenti apicidatis, apicibus late 

 nigrescentibus, spinis aliquibus albis intermixtis. 



Long. capitis caudaąue, 34- unc. ; pedis postici cum unguibus, 4. 



The form of the body is broadly oval, approaching to globular. 

 The spines are yellowi»h-white for about five eighths of their length, 

 then ringed with blackish, and are terniinated by a yeliovvish tip of 

 about one eighth of their length : hence results a general colour of 

 grizzled yello\v and black. 



The head is brovvn above, with an intermixture of white hairs. 

 The ears are covered with short vvhitish hairs. The hairs of the 

 chin and lower jaw are also vvhite, with the exception of a patch of 

 brown in the middle of the hinder part towards the-throat. The 

 under surface is pale brown. 



The ears are less thickened towards the tip, and more acuminated 

 than jn the preceding species. lihe moiistaches do not reach beyond 

 the tips of the ears. 



In the younger specimeh the colour, both of the upper and under 

 surface, is much darker than in the adult. 



The exhibition was resumed of the nevv species of Skells collected 

 by Mr. Cuming on the vvestern coast of South America and in the 

 islands of the South Pacific Ocean. Those exhibited on the pre- 

 sent occasion vvere accompanied by descriptions from the pen of 

 Mr. Broderip.
