OBSERVATIONS ON QUADRUPEDS. 



are of a deep ochraceous yellow, approaching to 

 ferruginous ; the abdomen pale yellow, with the 

 edges of the segments deep brown ; their general 

 form is oblong.* Adhering to many of the hairs of 

 Wool near the roots, we found a great quantity of 

 the nits, or eggs, of these parasites. These were 

 dirty white, of an oval-oblong form, about three- 

 eighths of a line in length, and between two and 

 three times as long as broad. They were applied 

 laterally to the hairs on which they were fastened, 

 and were furnished at one extremity with a short 

 neck, having apparently an aperture resembling the 

 mouth of a phial. This aperture was in all cases 

 directed from the root of the wool.

 may be uncommon in this country, or, what is more likely, has 

 been overlooked, as Mr. Denny states his never having seen any 

 specimen except the one which I forwarded to him for examination.
