It is now in the Berlin Museum, and is figured in Bloch and Schneider's Sijsteiua, pi. 106. The upper point of the snout is wanting, which explains the cause of the absence of half the teeth in Schneider's figure. That the head is represented as being scaly, is a liberty taken either by the designer or engraver. The specimen is now wholly faded, and shows the merest traces of its original markings. According to the authors of the Jlora; Ichtln/olofiica;, this individual has 305 rays in the anal fin ; Bloch and Schneider give the nimiber as 292, and Seba as 290. All these enumerations are erroneous, and Bloch and Schneider do not seem to have taken the trouble of reckoning them, but merely to have deducted four from tlie number mentioned by Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original British Museum (Natural History).
