Seite 499 - The upper pharyngeals have a rather irregular form ; they are slightly arched, the convexity being directed towards the pharyngeal cavity, tapering anteriorly, and broad posteriorly. They are coated with a thick, soft membrane, which reaches far beyond the margin of the bone, and is studded all over with minute horny cilia. Each branchial arch is provided with a series of long gill-rakers, which are laterally bent...
Seite 499 - Genera 3; species 70-80; inhabiting the fresh waters and coasts of warm regions, feeding on organic matter contained in mud. A considerable indigestible portion of the latter is swallowed, and in order to prevent larger bodies from passing into the stomach, or substances from passing through the gill-openings, these fishes have the organs of the pharynx modilied into a filtering apparatus.
Seite 363 - Each scale bears upon its inner anterior margin a thick solid bony rib, extending upwards beyond the margin of the scale, and sliced off obliquely above and below, on opposite sides, for forming splices with the corresponding processes of the adjoining scales. These splices are so closely adjusted, that without a magnifying power, or an accidental dislocation, they are not perceptible. When in situ and seen internally, these continuous lines decussate with the true vertebral apophyses, and cause...
Seite 508 - ... side the rudimentary ventral spine, but no cartilage. The posterior peripheric portion is suspended on each side on the coracoid, the upper bone of which is exceedingly broad, becoming a free, moveable plate behind the pectoral.
Seite 355 - I am making this all up, as the children say, out of my own head — " the barramunda is said to be in the habit of going on land, or at least on mud-flats ; and this assertion appears to be borne out by the fact that it is provided with a lung.
Seite 515 - ... or if one sees its own image in a lookingglass, the little creature becomes suddenly excited, the raised fins and the whole body shine with metallic colours of dazzling beauty, while the projected gill membrane, waving like a black frill round the throat, adds something of grotesqueness to the general appearance. In this state it makes repeated darts at its real or reflected antagonist. But both, when taken out of each other's sight, instantly become quiet.
Seite 630 - ... whilst in a large lake or river, where it finds abundance and variety of food, it attains to a weight of fourteen or sixteen pounds. Such large River trout are frequently named and described as Salmon trout, Bull trout, etc. Further, in Salmones as in the majority of fishes and tailed Batrachians, there is an innate diversity of growth in individuals hatched from the same spawn ; some grow rapidly and normally, others more slowly, and some remain dwarfed and stationary at a certain stage of development....
Seite 270 - ... interspersed. But the appearance of these was still inferior to that of the multitude of fishes, that glided gently along, seemingly with the most perfect security. The colours of the different sorts were the most beautiful that can be imagined; the yellow, blue, red, black, &c. far exceeding any thing that art can produce. Their various forms, also, contributed to increase the richness of this submarine grotto, which could not be surveyed without a pleasing transport...
Seite 515 - They were kept in glasses of water, and fed with larvae of mosquitoes, and had thus lived for many months. The Siamese are as infatuated with the combats of these fish as the Malays are with their cockfights ; and stake on the issue considerable sums, and sometimes their own persons and families. The license to exhibit fish-fights is farmed, and brings a considerable annual revenue to the King of Siam. The species abounds in the rivulets at the foot of the hills of Penang. The inhabitants name it...
Seite 635 - Hist. Pise.' p. 194), had already expressed his belief that the different Salmonoids interbreed, and this view has since been shared by many who have observed these fishes in nature. Hybrids between the Sewin (S. Cambricus) and the River Trout (S. fario) were numerous in the Rhymney and other rivers...
