 and all the under parts of the head and body, very light brown, almost white. Two dorsal 

 fins slightly connected by a membrane of a light brown color, mottled with dark brown. 

 Anterior portion of the body hexagonal. Under the muzzle are small barbules, covering the

2. Aspidophorus acipenserinus, Tilesitjs. 



Of a light, yellowish gray color, browner above, with transverse undulating brownish 

 lines. It is distinguished from the preceding by wanting the barbules on the branchioste- 

 gous membrane, and the numerous polygonal plates, marked with stelliform streaks, which 

 cover the breast before the ventrals ; while, in the European species, that part is covered by 

 four plates only, arranged in a square form.
