COMMENTS AND QUERIES 



CONTINUED. 



Teleost is the name applied to fish 

 which have a fully ossified skeleton. 



According to the Reverend Batenian 

 eels have been known to live in aquaria 

 for twenty and thirty years. 



The addition of small pieces of plaster 

 of paris to the aquarium, materially 

 assists the snails in forminir the shell. 



Tritons or newts in common with 

 lobsters and some other lower animals, 

 have the power of reproducing lost limbs. 



In Japan Daphnia is called mijinko. 

 As much space and attention is given 

 to its propagation as to the fish to which 

 it is fed. 



All fish of the genus Carassius to 

 which the goldfish belongs, are without 

 barbels. The barbels are fleshy elongat- 

 ed projections, usually about the head, 

 in fishes. 



The goldfish was first introduced into 

 Japan from China at the beginning of 

 the Sixteenth Century. It was brought 

 to Europe in 1611 and later to the 

 United States. 



The climbing perch (Anabas Scan- 

 dens) when migrating from a pool which 

 is in danger of drying, usually chooses 

 the night or early morning, while the 

 dew is still on the vegetation. The 

 specific name scandens means climbing. 



At the meetings of the various socie- 

 ties, inquiries are constantly being made 

 which arouse interesting and profitable 

 discussion. Why not elaborate upon 

 such questions and form articles for 

 publication in The Aqnarium, or at 

 least a short item for this page? Local 

 editors please take note. 



It has been asserted that a carp weigh- 

 ing twenty pounds will contain more 

 than a million eggs. 



It is said that snails will eat the gel- 

 atinovis envelope of frog eggs, thereby 

 causing the death of the tadpole. Has 

 anyone observed this habit? 



If this copy of The Aquarium is of 

 no special interest to the reader of this 

 item, it would be a favor to hand 

 it to some one interested in the 

 subject. It would certainly be apprecia- 

 ted by the management, and also, prob- 

 ably by the one to whom it is given. 



"Those salmon that are taken in the 

 river Mersey in Cheshire, the first year 

 are called smelts, the second sprods, the 

 third morts, the fourth fork-tails, the 

 fifth half-tails, and the sixth, when they 

 have attained their proper growth, are 

 thought worthy of the name of salmon". 

 From Art of Angling published in 1774. 



Contributors will add to the value of 

 their articles by using all common, as 

 well as the scientific name of the subject 

 discussed. Many animals have popular 

 names that vary considerably in diff'erent 

 localities. All are indispensable, as we 

 aim to interest all classes of investiga- 

 tors. Many microscopic organisms, and 

 those that are of such infrequent occur- 

 rence as not to attract attention, may 

 not have a vernacular, however. 



Catfish are at once our largest and 

 smallest native fish. The little stone 

 cat is mature at three inches, whereas 

 the mudcat attains a weight of one 

 hundred pounds. The giant sheatfish, a 

 member of this family, occurring in 

 Europe abundantly in the Danube, 

 weighs as much as three or four hundred 

 pounds, being next to the sturgeon, the 

 largest European fish. A number of 

 tropical species of catfish are popular 

 with aquarists.
