sider Brunelli's insect as a little known species of this genus 

 till the natural history of it has been better explained. The 

 following is his account of it ; — " The Brasilians give the 

 name of cnndiru to an insect shaped like a small worm, 

 which, when stroked with the finger in one direction, is 

 smooth, but when stroked in the other feels so rough that 

 it wounds the finger. It is greedy of blood from wounds ; 

 it is dangerous to the crocodile when wounded in the water, 

 and is found in nianv places in nuillltudes. It makes its 

 way into the limbs of the natives, and cannot be taken out 

 without la\ing open the part : the men, therefore, must be 

 very cautious when they go into the rivers."

J. HE system of the mammalia, which I have made the 

 foundation of my Manual of Natural History, and which 

 has been followed by various naturalists in their works, 

 will, 1 hope, be rendered more agreeable to nature, and 

 more perfect, by the following alteration, which has been 

 occasioned, in particular, by the discovery of the ornitho- 

 rhyncus paradoxus. The organs of motion are made the 

 chief ground of these orders, because they soonest strike 

 the attention, and are in the most intimate relation with the 

 whole habits of the animals. I have, however, subdivided 

 two of them, which comprehend a great variety, into two 

 families, according to the diversity of their incisor teeth, and 

 distinguished tliem by the known names of some Linnaean 

 orders, that those whole classes are arranged as follows : 



I. Order. Btmancs. 



1. Homo. 



II. OuADRUMANA. 



2. Simla. 



3. ]\-ipio. 



4. Ccrcopithecus. 



5. Lemur.
