256 THE HISTORY OF ANIMALS. [B. IX. 



6. Among river fish the male glanis is very careful of 

 his young fry, but the female goes away as soon as she has 

 deposited her ova, but the male continues to watch by the 

 greater number of the ova, paying them no more attention 

 than to drive away other fish, that they may not carry away 

 the ova; he is thus employed for forty or fifty days. 

 until the young fry are so far grown that they can es- 

 cape from other fish ; the fishermen know when it is guarding 

 its ova, for it drives away other fish, and as it jumps at them 

 it makes a noise and a murmur. It remains with such af- 

 fection beside its ova, that if they are deposited in deep 

 water, and the fishermen attempt to bring them into 

 shallow water, the fish will not forsake them ; but if 

 young it is easily taken with a hook, from its habit of seizing 

 upon any fish that may come in its way ; but if it is ex- 

 perienced, and has swallowed a hook before, it does not 

 leave its ova, but with its hard teeth it will bite and destroy 

 the hook. 



7. All creatures with fins, and stationary animals, inhabit 

 either the places in which they \vere born, or similar lo- 

 calities, for their peculiar food is found in such places. The 

 carnivorous fish are the greatest wanderers ; all are carni- 

 vorous with a few exceptions, as the cestreus, salpa, trigla, 

 and chalcis. The mucous substance which the pholis emits 

 forms around it, and resembles a chamber. Of the apo- 

 dal testacea, the pecten is the most locomotive, for it flies 

 by means of its own valves ; the purpura and its congeners 

 advance very slowly. 



8. All the fish except the cobius leave the Pyrrhic Euripus 

 during the winter on account of the cold, for the Euripus is 

 colder than the sea, and return again in the spring. In the 

 Euripus the scarus, the thrissa, all the thorny fish, the galus, 

 acanthia, carabus, polypus, bolitaena, and some others are 

 wanting, and of those that are produced in the Euripus, the 

 white cobius is not an inhabitant of the sea. Those fish 

 which have ova are in the highest season in the spring, 

 before they produce their ova ; those that are viviparous in 

 the autumn, and besides these the cestreus, trigla, and their 

 congeners. In the neighbourhood of Lesbos, both the ma- 

 rine fish and those of the Euripus produce their ova in 

 the Euripus; they copulate in the autumn, and deposit
