The host, when found, will problaby prove to be some of the 

 numerous marine invertebrates. This species has been found 

 around the British Isles and in the Gulf of Naples as well as 

 in Spitzbergen. 



Csiligoidsi — Caligidae. 

 Caligus halistae Steenstrup & Lütken. 

 Fifteen females and three males of this species were taken 

 from a species of Balistes on the Australian coast by Wideröe. 

 This parasite was originally obtained in the West Indies and was 

 afterward noted by Brian in the Mediterranean. Although the 

 host of the present specimens was the same genus of fish the 

 locality is very far removed from both the others. 



Caligus zei Norman & T. Scott. 

 Six females were obtained from the gills of the common 

 dory, Zeus faber, at St. Vaast de la Hougue i France. The 

 species is confined to this fish for its host and has not been 

 found away from the English Channel. 



Caligus cheilodadyli Krøyer. 

 A;^single female was obtained from an unknown host at the 

 Madeira Islands off the coast of Marocco. Kroyer's original 

 specimens were obtained from a fish of the genus Gheilodactylus 

 captured at Valparaiso, Chile. The present specimen thus gives 

 us a new locality and probably a new host if that were known. 



Caligus diaphanus Nordmann. 

 Six females and a male of this species were taken from the 

 gill cavity of Trigla corax at St. Vaast de la Hougue in France. 

 This parasite has been found upon various species of gurnards 

 (Trigla) around the British Isles and in the Channel.
