(5) Fish may act as intermediate or definite Hosts. — An example of the f ormei* 

 is found ir Lota vulgaris, which is commonly known to harbour the larval 

 form of Bolhriocephalus lotus (see Cestodes). Congers are said to be infested 

 with hydatids. A curious case has been described by Dr. Batten, namely, 

 the fixation of a species of Lepcoplitluirus, one of the " Calegidse' 1 or fish lice 

 on to the cornea of a fishmonger (which specimen he kindly sent to me). 

 These semi-parasitic copepods are very numerous on many flat fish, moving 

 about actively on the skin some time after the death of the fish. The saline 

 condition of the ocular conjunctiva, with a certain quantity of mucous secre- 

 tion, render this position particularly suitable for these parasites if acci- 

 dently introduced. It is, however, very rare : 1 have never heard of or seen a 

 second case. The parasite was successfully removed, vision not being 

 impaired.
