This is a vintage scientific illustration of a cephalopod, specifically a Histioteuthis Bonelliana. The illustration is on a yellowed, aged paper background with faint grid lines. The cephalopod is depicted in a central, symmetrical pose. It has a reddish-pink body with numerous small, dark blue circular spots covering its mantle. The cephalopod has ten appendages: eight arms and two longer tentacles. The arms and tentacles are slender and elongated, with a slightly darker reddish hue than the body. The tentacles are adorned with small, circular suckers along their length. The illustration highlights the unique features of this species, including its elongated body and the arrangement of its arms and tentacles. At the top of the image, the text 'CEPHALOPODES' and 'Pl. 19' are visible. To the right, 'G. Histioteuthis' is written. Below the illustration, the species name 'Histioteuthis Bonelliana' is printed, along with the artist's name 'Ferrer'.
