A number of specimens of this Cope pod can usually be 

 found by pressing the nostrils of Cod, .so that mucus, &c, 

 may be ejected. The mucus is then placed in a drop of 

 water, and the copepods, if present, are easily seen. The 

 females have two large white egg sacs. 



From small cod caught in Barrow Channel, August, 

 1900 ; and also in the nostrils of large cod caught on the 

 offshore fishing grounds between Lancashire and Isle-of- 

 Man, March, 1901.

This is a well marked species, and may easily be dis- 

 tinguished from other Caligi by the long slender anten- 

 nules and large caudal stylets. The second foot- jaws in 

 the male are powerful grasping appendages. 



Frequent in the mouth of the Bass (Ldbrax lupus), 

 caught in Barrow Channel, August, 1900. 



Length of female, 4'9 mm. ; male, 6*9 mm. It is rather 

 unusual to find the males of oopepod fish parasites larger 

 than the females. 



20.— Caligus brevicaudatus, n.sp. PL II., figs. 7-10. 



Length of female, 5'3 mm. The characters which dis- 

 tinguish this species from the other members of the genus 

 are, 1° the extremely short abdomen and caudal stylets ; 

 2° the fourth pair of feet, the expedite of which is very 

 slender. 



Inside the mouth of the Common Gurnard (Trigla 

 gurnardus) caught in the vicinity of Piel, August, 1901.
