into numerous prickle-like ere6l processes along the 

 course of the body, giving it a most peculiar appearance. 

 The obje6l thus appears to be a pale yellowish-brown 

 fibred inseft, provided with numerous processes. The 

 Saprolegniese usually attack dead flies, etc., but in this 

 case, from the position on a tree where the moth was 

 taken, it would seem to have been attacked before 

 death — possibly during injury or disease. The specimen 

 was forwarded from the Wieroonie distri6t, where the 

 cassava fields of the Indians were, a year or two ago, 

 utterly destroyed by the caterpillars of the above-named 

 moth, several of which were sent to me by Mr. TAYLOR 

 for identification. 



An internal Parasite. — A case that seems worthy of 

 mention, of the occurrence of the Small Thread Worm 

 (Oxyuris vermicularis) , was quite recently submitted to 

 me through Mr. Van Praag of Surinam. The little 

 parasites were from the re6lum of an infant about three 

 months old, and they were found to exist there in aston- 

 ishing quantities. It was a peculiar feature of their 

 occurrence that they were all males — at least the chance 

 ones taken for examination and submitted to me were all 

 males : but it may well be that to the untrained eye, the 

 differences between the sexes, so clearly marked though 

 they be, were not recognised when they were being 

 picked out from the mass.
