Car. de Martius Lectori salutem!
Jl raefaturus in descriptiones piscium brasiliensium quas ad exempla in Museo R.
Monacensi exhibita exarare Agassiz noster in se suscepit, de tristi jactura amicissi-
mi J oa. de Spix , strenuissimi per iter socii, quin moestus conquerar, facere non
possum. Propositum illi per hoc iter erat, omnes regni animalium partes rimari,
quo factum est, ut, perspicax aeque ac indefessus in observando ut erat, magnam
memoria dignissimarum observationum copiam comparaverit, quae tarnen post ejus
mortem, cum plerfcque ejus scriptis, misere perierunt. Quod ad pisces attinet,
nil praeter icones jam in lapide delineatas reliquit, quam ob causam nobis est ex-
pectandum, dum alius quis peregrinator de piscium natura, moribus, per aquas
distributione rel. satagens, nostram jacturam sarciat. Mihi quidem, divitiis Florae,
per vastum Brasiliae imperium incredibili luxurie exuberantis, allecto atque in his
colligendis cumque cura observandis quam maxime occupato, non lieuit, nisi quasi
aliud agendo, et natura sese quodammodo obtrudente, de piscibus non tarn obser-
vationes quam observationum fragmenta instituere, quae Tibi, benevole Lector, heic
dum offero, defectuum veniam a Tua aequitate. me impetraturum esse confido.
Duo vero haec scribenti mihi sunt proposita: primum quidem , ut observatio-
nes quasdam de piscibus in genere commemorem tarn maritimis quam flumina stag-
naque incolentibus, singularium etiam quorundam piscium indolem enarrem; tum
etiam ut, quibus artibus ab incolis capiantur, et quem ad vitam et rem oeconomi-
cam usum habeant exponam.
Piscibus, quos brasilienses jure dicimus, vix in alia quavis orbis terrarum parte
ampliorem, imo aeque amplum , in quo degant, campum concessum fuisse,
is facile intelliget, qui longissimum ilium tractum orae maritimae consideret, quam
Oceanus atlanticus alluit, fluminaque ingentia in hunc demum aquarum immen
