190 On Three apparently new Gopepods from the Clyde, 

 Bob. Kilbrennan Sound, Firth of Clyde, 1886; apparently 



rare. 



Remarks. — The Copepod of which the above is a descrip- 

 tion does not resemble any described species known to us; 

 we are also unable for the present to ascribe it to any known 

 genus, and the name we have applied to it refers to its some- 

 what anomalous structure and position. The peculiar form 

 of the thorax of this Copepod was the feature that first 

 attracted attention to it, and the subsequent examination and 

 dissection of it revealed the abnormal character of the species. 

 It is a Copepod that appears to be either a parasite or a 

 commensal.
