30. Monstrilla anglica, Lubbock. 



All appear to be about equally common, or rather uncommon, 

 for with the exception of a remarkable gathering taken in St. Aubin's 

 Bay, at 9 p.m., on July 19th, 1897, when several dozen specimens of 

 T. thompsoni occur, a few specimens only of it and the other species 

 were present on only two or three occasions, and during the summer 

 months. 



An interesting article upon Monstrilla anglica, by Mr. J„ 

 Horneli, appeared in Vol. I., part 2, page 42, of the present Journal. 



Family : — Sapphibinime. 



31. Lichomolgus fueicolus, Brady. 



One specimen only of this semi-parasitic species was found in 

 an evening gathering from St. Aubin's Bay. 



In conclusion, while a few species are absent which might have been 

 expected to be present in an English Channel collection, it is probable 

 that the above enumerated list is a fair representation of the free 

 swimming Copepoda of the district. Doubtless any specialist devoting 

 himself to their systematic collection consecutively, might considerably 

 add to the number, and deduce valuable information as to their habits, 

 and bearing on our supply of food fishes, and the causes which lead to 

 the appearance of particular species at varying or definite periods. 



The large number of sedentary species of Copepoda living at all depths 

 on the sea bottom, and readily collected by careful washing from dredged 

 material are not here alluded to, as also are not included the many 

 highly organized forms as well as curiously degenerate species of 

 parasitic Copepoda, which are found attached to the gills, scales or other 

 parts of most fishes. 



Each of these interesting classes might at a future time furnish 

 material for special reports as distinctly different branches of the subject, 

 and both capable of being well studied at the Channel Islands.
