118 DR. T. s. cobbold's LIST OF ENTOzoA. [Mar. 26, 



from IMadagascar, where the thorax and Uver were crammed with a 

 very singular form of Coenurus : the several bunches or colonies of 

 them in the right side of the chest had caused a remarkable atrophy 

 of the right lung, that of the left side being also much diminished 

 in bulk. The liver was similarly affected. 



In all cases I have been careful to ascertain, as far as possible, 

 whether or not the several species of Entozoa found by me were pre- 

 viously known to science ; I mention this because I have no wish to 

 imitate those who take little trouble ou this score, and carefully de- 

 scribe every parasite as new, which may haply or otherwise come 

 within their possession. Excluding pentastomes, 31 of the following 

 are adult forms, and yet only II of these proved new to science ; a 

 few of the latter being peculiar and of great interest.
