Cuvier, in a note at p. 337 of the ‘ Régne Animal,’ vol.ii, affirms, 
from ‘‘ an immediate comparison,” the identity of Risso’s Lepidole- 
prus celorhynchus of the Mediterranean with the Macrourus rupestris 
of Bloch, which is described and figured by that author with the 
first ray of the first dorsal fin distinctly serrated in front. Yet Dr. 
Richardson, in the Proceedings of the Zoological Society for 1839, 
p- 100, speaks of “examples of celorhynchus from the Mediter- 
ranean and also from Madeira’’—meaning, by these latter, my Ma- 
crourus atlanticus, Proceed. Zool. Soc. 1839, p. 88; Trans. iii. p. 15— 
** both in the Society’s Museum, none” of which ‘ have the first 
dorsal ray serrated.” 
Awaiting, therefore, further definitive information regarding the 
true L. celorhynchus of Risso, in reference to this character, I am 
compelled to give a distinct name to this second Madeiran species of 
Macrourus, which has the dorsal spine serrated at its fore-edge, but 
which, by its shorter muzzle and somewhat smaller and rounder eyes, 
appears, waving the question as to the serrature or non-serrature of 
the dorsal spine in Risso’s fish, to approach even nearer than M. at- 
lanticus to his L. celorhynchus. 
A single example only has occurred, which was not seen till it had 
been partly dried... 
Macrovrus tavis. WM. pallidus, griseus, lucidus, levigatus s. exi- 
lissime areolato-scaber, inermis; squamis inconspicuis minutis : 
capite rostroque acuto abbreviatis, simplicibus (nec celatis nec ca- 
rinatis) ; oculis rotundatis ; dentibus in mavilla inferiore validis, 
uniseriatis : pinne dorsalis prime radio primo inermi ; ventralium 
simplici.

This third Madeiran species of Macrourus is immediately distin- 
guishable from the other two by its glossy, sleek or apparently naked 
appearance, caused by the fineness and minuteness of its areolz or 
scales. It is also a more elongated fish. In the formation and pro- 
portions of the head, eyes and muzzle it nearly agrees with M. ser- 
ratus, and it has also the cheeks plain and flat, without the strong 
sculptured subocular keel which gives so singular and trigloid an 
aspect to the head of M., atlanticus. 
The only individual which has occurred was sixteen inches long.

The occurrence in Madeira of a single individual, imposes the ne- 
cessity of proposing, in lieu of the barbarous vernacular appellation 
Fierasfer, a name founded on an obvious character, and accordant 
with the rules of scientific nomenclature.
