1 quite small specimen from stat. 42, Port Louis, Falklands, depth 8 m., mud 

 and shells. 26th of July 1902. 



I specimen from stat. 52, Port Williams. Falklands, depth 17 m., sand. 3d of 

 Sept. 1902. 



I specimen from stat. 53, Port Williams, F"alklands, depth 12 m., sand and gra- 

 vel. 3d of Sept. 1902. 



All these species belong to the variety termed ''micropiis" by Smitt. ' The 

 smallest specimen (from stat. 42) measured only 25 mm. and was pictured, when 

 still alive, by Dr. Skottsberg (PI. I fig. 5). 



Both these species of Pliucocoetcs have been described from the Falklands before. 



II. Maynea patagonica CUNNINGHAM. 



I specimen from stat. 53, Port Williams, Falklands, depth 12 m., sand and gra- 

 vel, 3d of Sept. 1902. A young specimen labelled "greyish white with 12 brown 

 transverse bands". 



This species appears to be new to the Falklands, its hitherto known distribu- 

 tion being more western. 



From the coast of Chile Steindachner has described " transversally banded 

 specimens of this species collected by PLATE and such a pattern maj' be the com- 

 mon (among the young?), although the type was uniform. 



12. Ilucocoetes fimbriatus Jenvn.? n. subsp. fasciatus. 



I specimen among roots of kelp hauled up from a depth of 7 m., Greenpatch, 

 Port Louis, Falklands. 27th of Jul}- 1902. 



The genus Ilucocoetes appears to be imperfectly known and it contains, no doubt, 

 more than one species although hitherto only the specific name ßnil'riatiis originally 

 given by Jenyns has been used. This specimen from the Falklands has a rather 

 striking colouration being dark brown with 5 — 6 more or less developed whitish 

 transverse bars. For fishes living among algœ such a colouration must be of pro- 

 tective value, but at the same time transversely banded forms are numerous among 

 the Lycodidce, especially when they are young, so that such a pattern must con- 

 sequently represent at the same time an ancestral characteristic in that family. It
