under surface. The most common and most widely-distri- 

 buted of these fishes, is that known as Bellows-Fish, 

 Trumpet-Fish or Sea-Snipe (Centrisctis scolopa.r) ; which, 

 while occurring on the Australian coast, is also found

on portions of the coast of Europe. Another and a, 



smaller one which is found on our coast is the "Little 



Bellows- Fish " (Centriscus graciUs). This is the species 



here illustrated. It, also, is very widely distributed. I have 

 obtained this species on fine moonlight nights when it was 



being washed up during a south-easterly breeze, on the 

 Ocean Beach at Manly, N.S.W. 



SEA-HORSES AND PIPE-FISHES. 



(Family: Syngnathidce.} 



MOST of my readers are, no doubt, familiar with those 

 comical-looking little fishes known as Sea-Horses ; and, 

 though a lesser number will have met with the Pipe-Fishes, 

 these may be described roughly as being really "straight- 

 ened out" Sea-Horses. In these fishes the gill-openings are 

 reduced to a very small aperture near the upper posterior 

 angle of the gill-cover. They only possess one soft dorsal 

 fin, which, in all of the species, is used largely for locomo- 

 tion in some solely. They have no ventral fins, and some- 

 times one or more of the others are also absent. In the 

 Sea-Horses, the tail is prehensile, being used to hold on to 

 marine plants or other objects while resting or feeding: 

 while in the Pipe-Fishes the tail is not prehensile, and is 

 usually provided with a small terminal fin. The rate of 

 progress of these fishes particularly the former is verv
