NOUl'UKUN CliiMJiKA. Cki-nuera 



shape of the head aiid first dorsal fin, and by a pair of bony appendages close to the 

 ventral fins. It is not a large species, seldom exceeding a yard in length. 



In the seas of the southern hemisphere, there is another species of Chimsera, called 

 from its locality, the SOUTHEKN CHIMJEEA (Call&rhynchus antdrctica) or ELEPHANT-FISH, 

 the latter title being given to it on account of the extraordinary prolongation of the 

 snout. The Araucanian name for this species is CHALGUA ACHAGUAL. The snout of 

 this fish is developed into a strange cartilaginous prolongation, which is bent back- 

 wards in a hook-like form, and is thought by some persons to bear a resemblance to 

 a common hoe. 



The tail of this species does not correspond in oddity with its head, being without 

 the long filament that gives so strange an aspect to its Northern relative. The colour 

 is satiny white mottled with brown, and the size is about the same as that of the 

 Northern Chimsera. 



THE fishes belonging to the next sub-order have their gills fixed by their outer edge 

 to the divisions in the gill-openings at the side of the neck. This sub-order includes 

 the Sharks and the Bays, many representatives of which creatures are found on the 

 British coasts. 



The first family of this large and important group is known by the name of Scyllidse, 

 and its members can be recognised by several distinguishing characteristics. They 

 have spout-holes on the head, and the gill-openings are five in number on each side. 

 Sometimes there only seem to be four openings, but on closer examination the fourth and 

 fifth are found set closely together, the opening of the fifth appearing within that of the 

 fourth. The teeth are sharp and pointed, and the tail is long, notched on the outer side, 

 and is not furnished with a fin. 



One of the commonest British species is the LITTLE DOG-FISH, called by several 

 other names, as is usual with a familiar species that is found in many localities. Among 

 such names are SMALL SPOTTED DOG-FISH, LESSEE SPOTTED SHAKE, MOE.GAY, and 

 ROBIN Huss.
