 can give a sufficiently comprehensive account of their structure 

 to make such publication useful. The present communication 

 contains a fairly full anatomical account of three new species, of

 I have been able to study two specimens only. But I have 

 been fortunate enough to fill up most of the descriptions which 

 are chiefly requii-ed to detei-mine its systematic position with 

 accuracy. 



On a Species of Oochoristica. 



I refer a number of individuals from the Lesser Anteater,
