NOTOTHENIIDAE

(125-250 mm.) in the British Museum collection from the Falkland's, Orange Bay, 

 Isthmus Bay, Latitude Bay, and Sandy Point, including the types of the species and 

 2 specimens identified by Thompson as N. longipes, received from the United States 

 National Museum. 



This species appears to inhabit shallower water than the closely related N. ramsayi, 

 from which it may be distinguished by the smooth scales on the upper surface of the 

 head, rather larger mouth and smaller eye, narrower interorbital region, smaller average

number of gill-rakers, lower spinous dorsal fin, and generally darker colour. Mr Bennett 

 notes that N. wiltoni is very common at certain seasons at the Falkland Islands, where 

 it is known as " Rock Cod ", a name also used for other species of Notothenia. According 

 to him this fish seems to come to the shore in November at Stanley, and to leave at 

 about the middle of April. As specimens taken in April showed enlarged reproductive 

 organs, Mr Bennett assumes that the departure from Stanley is for breeding purposes. 

 In the Falklands this species is found round jetties and in the "kelp", lurking under 

 shelter during the day and becoming active about sunset.
