THE LITTLE DOG-FISH. 



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

 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 Chimaera, callec 

 from its locality, the SOUTHERN CHIMERA \Callorhynchus antarctica) 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 o: 

 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 color 

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

 Northern Chimaera.

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 Rays, 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 recognized 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, LESSER SPOTTED SHARK, MORGAY, 

 and ROBIN Huss.
