"If we do not know every one of them, if nature still keeps ichthyological secrets from us, nothing is more admissible than to accept the existence of fish or cetaceans of new species or even new genera, animals with a basically 'cast-iron' constitution that inhabit strata beyond the reach of our soundings, and which some development or other, an urge or a whim if you prefer, can bring to the upper level of the ocean for long intervals.
They have sometimes in ichthyological systems been referred to the Scombridæ and other marine families, from the circumstance that the dorsal fin anteriorly is composed of spines.
A great number and variety of collections, now making part of the ichthyological treasures of the Museum at Cambridge, were forwarded to him in answer to this appeal. Indeed, he now began to reap, in a new form, the harvest of his wandering lecture tours.
Then comes the continuation of the description of the Ganoids and the Scomberoids, and an additional sheet contains a sketch of my ichthyological classification. The plates are even more successful than those of the first number. If all goes well the third number will appear next July.
"I want a good picture of the Grotto Azzurra but I cannot find one. Those that are offered for sale are such poor imitations." After the concert was over, we entered the salt water aquarium of Naples, which is famous throughout Europe as the finest and largest ichthyological collection in the world.
The piraracu, for instance, is found everywhere from Peru to Para; and so are a few other species more or less extensively distributed over what may be considered distinct ichthyological fauna. But these wide-spread species are not migratory.
Having by permission of the Director of the Museum one of the finest collections of fossils in Germany at my disposition, and being also allowed to take the specimens home as I need them, I have undertaken to publish the ichthyological part of the collection. Since it only makes the difference of one or two people more to direct, I have these specimens also drawn at the same time.
Death of Leuthold, the Guide. Although his glacier work was now so prominent a feature of Agassiz's scientific life, his zoological studies, especially his ichthyological researches, and more especially his work on fossil fishes, went on with little interruption.
And so the monster surfaced again, despite the endless witticisms heaped on it by the popular press, and the human imagination soon got caught up in the most ridiculous ichthyological fantasies. After I arrived in New York, several people did me the honor of consulting me on the phenomenon in question.
The blueback, a lively and toothsome fish, about which rages an ichthyological argument as to whether he is a distant species of the salmon tribe or merely a half-grown coho, is the first to show in great schools. The spring salmon is always in the Gulf, but the spring is a finny mystery with no known rule for his comings and goings, nor his numbers.
