Art. I. — Notices of Irish Entozoa. By James L. Drummond, 

 M.D., Professor of Anatomy in the Royal Belfast Institution, Pre- 

 sident of the Belfast Natural History Society, &c. 



In the present paper and in those which shall follow relating 

 to Entozoa, it is my intention to adopt almost solely the 

 classification and nomenclature of Rudolphi, not that I con- 

 sider either of these as being perfect, but because this branch 

 of Zoology is still in too backward a state to admit of much 

 certain, or probably permanent change, from the system laid 

 down by that illustrious naturalist. I have chosen the term 

 " Notices," as being in truth that which will best express the 

 character of the communications I shall have to make, name- 

 ly, not a systematic and connected enumeration of orders, 

 genera, and species, but such facts and observations as may 

 be the fruit of my inquiries, however isolated these may be 

 from any determinate arrangement. Without further pream- 

 ble, therefore, I proceed to mention first, an intestinal worm 

 which is particularly frequent in fishes of the cod tribe ; viz. 

 the Echinorynchus Acus. 



The genus Echinorynchus is the only one included in the 

 second order of Rudolphi' s arrangement of the Entozoa, which 

 order is by him thus characterized.
